New Hanover County, North Carolina
Effective January 1, 2007
Appendix 2 - GlossaryPage 1
From time to time the Tax Administrator of New Hanover County may deem it necessary to add one or
another definition or appraisal policy (expressed as a business rule) contained in this Schedule of
Values, to address unforseen situations.
All such new definition and policy are hereby incorporated into this Schedule of Values except that no
new policy may negatively affect the integrity of (equality among) the valuations arising from the
implementation of and continuing use of this Schedule, as approved.
ACCESS (Microsoft Product)
Microsoft Access is a database program. The appraisal staff are generally knowledgeable of this
PC based package and management is adept in developingqueries and specialized tools

AIR CONDITIONING
The air in a building is actively cooled by permanently attached mechanical device(s), which may
also provide heat to building occupants. Devices that may be temporarily placed in a wall or
ceiling opening do not qualify the building as having conditioned air.

modules, and applies any exemptions to arrive at . ASMT stands for .
Taxable ValueAssessment
ASSESSED VALUE
In North Carolina, ?Assessed Value? is the same as ?Market Value. If a parcel is appraised for a
Market Value of $100,000, the Assessed Value is also $100,000. However to say that a parcel
has been ?assessed? means that someone has specifically done a Change Action on the
administrative module?s ASMT Screen, which moves the value from the appraisal module.
ASSESSMENT LEVEL
The state-mandated percentage to be multiplied by the market value estimate, however derived.
For real estate and personal property in North Carolina, the assessment level is 100%. If your
property is appraised for $100,000, your assessed value is $100,000 ($100,000 X 1.00).
ASSESSMENT RATIO STUDY
A statistical tool used by appraisers to measure the assessment level in a county. Each arms-
length sale, and each sold parcel's assessed value, is part of the market-selected statistical sample.
Appendix 2 - GlossaryPage 3
First, the ratio of assessed value to sale price is calculated by dividing the assessed value of the
parcel by the sale price of the parcel. This gives the parcel's assessment ratio.
Second, standard statistical analysis is applied to all assessment ratios (one ratio per sale, not per
parcel). This is the only measure of the quality of the appraisal effort for the year both in terms
of the Assessment Level and Uniformity of Assessments. See TAX ROLL, SEGREGATION.
ATTIC FINISH
The rate tables assume that residential buildings with any fractional story height contains living
space above the main heated areas.
Business Rule: If a house has an elevated roof pitch and/or dormers but was constructed
using a roof truss system that cannot be used (even for dry storage), charge the DWELDAT
record with Unfinished Area (removes the finish). See STORY HEIGHT and ROOF PITCH.
AUTOMOTIVE SERVICE GARAGE

BASE AREA
Also called Living or Heated Area (see BUILDING ADDITION).
Page 4New Hanover County Tax Office
BASEMENT AREA
In New Hanover County, with its high underground water table, discourages excavated
basements (but they do exist). Therefore we have defined three types of residential basement:
(1) Excavated (the hole is lined with poured concrete walls or concrete block walls, and floored);
(2) Pilings (typical of newer ?beach construction?); and
(3) Concrete Block , (typical of the older ?beach construction?, split-level and bi-level designs).
Use the ?Basement Finish? field to denote living area in these sub-main-floor areas.
A "furnace room" excavation with dirt walls (dirt and/or concrete floor) should not be picked up
as a basement, for any quality of residential or commercial structure.
Baths: HALF
The count of 2 fixture baths. The lump sum cost per bath is modified by the Quality Grade
modifier and is depreciated with the building.
Baths: FULL
The count of 3 fixture baths, otherwise known as a ?Full Bath?. The lump sum cost per bath is
modified by the Quality Grade modifier and is depreciated with the building.
Baths: EXTRA FIXTURE
The count of ?extra? fixtures, to include hot water heater, kitchen or bathroom sink, etc. The
lump sum cost per fixture contribution to building RCN will be modified by the Quality Grade
modifier and is depreciated with the building.
BEDROOM COUNT
The count of bedrooms. This data does not affect the value produced by the Cost Approach.
However "bedroom count" is a potential adjustment item in the Market Approach, so this data
needs to be accurately and zealously collected.
BIG BOX / DISCOUNT DEPARTMENT STORE
This is a commercial building STRUCTURE and USE which is large retail space with high
ceilings and minimal interior finish. This code has an influence on the Cost Approach, and the
Income Approach. Also please refer to the discussion of Net Operating Income below.
BUILDING
A building is a residential or commercial structure that has living (heated) area. While some
(such as detached garages) are certainly ?buildings? to the
Other Buildings and Yard Items
layman, they are not "buildings" to the CAMA system. The market simply does not treat these
structures the same as it does "normal" structures built to enclose living or working space.
Appendix 2 - GlossaryPage 5
Building Addition: LIVING (or BASE) AREA, or NON-LIVING AREA
A building must have one main living (heated) area. Most structures also have attached
amenities as porches, decks, and/or garages or in the commercial world, canopies.
Such amenities must be defined as building additions if the appraiser's intention is to depreciate
the porch, deck, garage, or canopy with the building.
BUSINESS RULE
A defines or constrains one aspect of our business, appraisal, and is intended to
Business Rule
assert structure on, control over, or otherwise influence how we appraise real estate. Business
rules must be well indexed in documentation and will have built-in Quality Control measures.
Business rules often focus on control issues. For example: ?

Business rules may pertain to value calculations. For example: ?All parcels in Neighborhood
will be appraised ?per Lot?.

COST APPROACH
The Cost Approach is one of three methods appraisers may use to estimate value (not every
parcel is a candidate suitable to apply all three methods). Also see MARKET and INCOME.
As a staff appraiser describes a building to the county?s CAMA system, the Cost module
automatically generates an estimate of value via the Cost Approach.
The CAMA system estimates the value of a given parcel?s improvements via the Cost Approach

CULTURAL FACILITY
This is a commercial building STRUCTURE and USE which is for museum-like space, almost
but not quite institutional in nature. This code has an influence on the Cost Approach, and the
Income Approach. Also please refer to the discussion of Net Operating Income below.
DEPRECIATION
In the Cost Approach, an appraiser may observe up to three kinds of depreciation to measure a
building?s loss in value (from ). They are:
Replacement Cost New
1. - Bone structure aging, condition of the structure, and the typical
Physical Deterioration
effective age in the given neighborhood are components of this type of depreciation;
2. (FO) - Functional problems within the structure, such as dysfunctional
unctionalbsolescence
FO
floor plans. Appraisers measure and enter FO as a percentage for this type of depreciation;
3. (LO or EO) - Locational problems, defined as
ocational (or conomic)bsolescence
LEO
problems that arise outside of the parcel's borders such as an adjacent junk yard or major
road. Appraisers measure and enter LO (EO) as a percentage for this type of depreciation.
The appraisal software ?looks up? the estimate of physical building depreciation from appraiser's
entries in the or and (CDU) fields. It applies the
Year Built Effective Year BuiltCondition
percentage found to the Replacement Cost New of all ?building? and its ?additions?.
Functional or Locational (Economic) Obsolescence must be manually entered from an appraiser's
observation of the property in question. The appraisal software then uses the entered percentage
to ?add to? the amount of Physical Depreciation for both residential and commercial buildings.
See PHYSICAL DETERIORATION, FUNCTIONAL and LOCATIONAL OBSOLESCENCE.
DRY STORAGE
This is a commercial building USE which is for space that was not designed for warehousing
purposes. Except for Roofed Rack type of storage space, this USE code is intended to describe
space whose only remaining use, as long as the roof continues to keep water out, is for storage.
This code has an influence on the Cost Approach, and the Income Approach.
DWELDAT

ECONOMIC OBSOLESCENCE
Locational problems, defined as problems that arise outside of the parcel's borders such as an
adjacent junk yard, are measured and entered into the appraisal software as a percentage for this
type of depreciation. (See the discussion under DEPRECIATION.)
Economic Obsolescence (EO) is typically measured by capitalizing the rent loss arising from the
problem. Apply EO evenly across all affected parcels as a percentage. Be roughly aware of the
dollar amount of change in the appraised value to help gain the correct percentage. Taper the
percentage used as the distance from the source of the problem increases.

Also, see PHYSICAL CURABLE DETERIORATION.
EFFECTIVE YEAR BUILT
The of a building is one of two major factors in the amount of physical depreciation
Year Built
for the building. The entry will override the building?s ?actual year built?.
Effective Year Built
In a building?s early years effective age and actual age are roughly synonymous. As the building
ages, Effective Age becomes more and more relative to where the parcel?s neighborhood is in its
, and somewhat relative to the condition of the structure. Together, the neighborhood?s
life cycle
life cycle position and building condition are always related to the effective age estimate (as
inferred from or).
Year Built Effective Year Built
To clarify the above paragraph's statement, ask the age-old appraiser's question: ?How can I say
this building has an effective age of ?fill in the blank? when is 50 years and the
Life New
building is already 150 years old?". The answer lies in the following "formula" (also see the
definitions for LIFE NEW and REMAINING ECONOMIC LIFE).

The decision should then revolve about the of the structure.
Remaining Economic Life
If given:

Then the formula (and logic) demands:

END USER
End user is a non-technical term employed by the staff of an Information Technology department
to identify those they serve. The typical end user is an expert in their field of endeavor. It is the
end user?s job to know what software tools are needed, and how to use them to accomplish the
job at hand. It is, therefore, the job of the Information Technology department to create and/or
otherwise obtain and maintain the tools and required infrastructure at peak operational efficiency.

assess the significance of a single term in the model rather than all the terms taken together.
FEE APPRAISER
A FEE appraiser appraises to solve a problem for the owner, or prospective owner, such as
financing - one parcel at a time.
One major difference between the MASS appraiser and the FEE appraiser is the amount of time
available to appraise each individual parcel. A fee appraiser will spend as much time as required
to understand and appraise a highly unique property while the mass appraiser must, of necessity,
spend far less time appraising the same unique property.
A second major difference arises from the fact that a FEE appraiser does not usually have to
consider any appraisal work done on surrounding parcels when estimating the value of a parcel.
Page 10New Hanover County Tax Office
On the other hand, equity between appraisals is critical for the MASS appraiser.
FEE SIMPLE
To appraise a parcel for market value is to assume that all rights of real ownership are
fee simple
intact and vested in the owner-of-record (except as permanently limited by powers of the state).
FENESTRATION
The arrangement, proportioning, and design of any openings in a building?s envelope (windows,
doors, skylights, soffits, archways, etc.) and accessories, or supplementary elements to a building.
By our definition ?fenestration? includes, but is not limited to, such accessories or supplementary
building elements as shutters, cornices, pilasters, lace-work, moldings, and built-in cabinets.
FIREPLACES
The count of fireboxes (openings) and chimneys (stacks). A fireplace is a metal
prefabricated
opening and, in most cases, a metal flue inserted into a wooden stack (a vent-free gas unit may
not have a stack). A masonry stack is a normal fireplace. This field is not a required entry.
Record the accurate count of openings and/or stacks for fireplaces (masonry or
Business Rule:
prefab). If the fireplace is closed off, determine the reason and enter sufficient Functional
Obsolescence to account for the cost to return the fireplace to functional service. Do not write
the fireplace?s contribution completely off via FO unless the stack must be replaced from the
ground up. Always explain any applied Functional Obsolescence thoroughly in notes.
FLEX SPACE
This is a commercial building USE which is designed to be flexible (the tenant can use the space
in many different ways including but not limited to retail, light manufacturing, and office uses.
This code has an influence on the Cost Approach, and the Income Approach. Also please refer
to the discussion of Net Operating Income below.
FUNCTIONAL OBSOLESCENCE (FO)
Appraisers measure functional problems within a structure, and enter an amount of Functional
Obsolescence (as a percentage) to address the issue. Functional Obsolescence (FO) include such
problems as dysfunctional floor plans for residential structures and ceiling height too low for fork
lifts to be used in warehouse structures.
Because we use the appraisal concept of Replacement Cost New (versus Reproduction Cost
New), most items of depreciation that are normally defined as Incurable Functional Obsolescence
are not in the building?s Replacement Cost New. The appraiser must always be aware of the
dollar amount of change in the appraised value to apply gain the correct percentage and fully
document the reasons for the application of Functional Obsolescence.

required by N.C.G.S. 105-283....? The goal of the Tax Department, then, is to handle this duty in
the most fair and equitable manner possible (so there are no problems for the Board to find). i.e.:
1.Review the appraised value of all real estate in the county (roughly 95,000 parcels) as of
January 1 each year formarket value, as defined in North Carolina law.

See MARKET VALUE for the definition according to N.C.G.S. 105-283.
2.Discover and value all unlisted real estate as of January 1 each year.
3.Hear all appeals where the owner disagrees with the Appraisal Division?s estimate of value,
or where the owner feels the value is discriminatory in some way.
When an owner appeals, the appraiser must come to a supported (documented) conclusion
of value taking into account all pertinent factors as the real estate market treated them for the
revaluation cycle. The appraiser?s decisions will not necessarily be for the same factors, or in
exact dollar amounts important to (or suggested by) the owner. Where market facts do not
support the appraiser?s value, the appraiser will give the benefit of any doubt to the appellant.

the use of the land is tightly restricted to only one named use and owner is required to go
through the entire zoning process to put the parcel to any other use. The appraiser will consider
the cost of re-zoning the property to its most likely permanent zoning-in-force and the effect of
the passage of time between January 1, 2007 and the time the likely date of such a change.
IAS
The appraisal and administrative software used by the Tax Administrator. The graphic on the
following page displays these two modules of IAS and the flow of values through the system.
INCOME APPROACH
The Income Approach is one of three methods appraisers may use to estimate value (not every
parcel is a candidate suitable for using all three methods). Also see COST and MARKET.
The Income Approach estimates the total value of a given parcel by modeling the decisions of the
typical investor in a given type of property. The Income module calculates the
Net Operating
associated with every part of the parcels capable of generating income.
Income
The CAMA system then applies a suitable to the Net Income via formula:
Capitalization Rate
. This is the same formula used to calculate the total
Value = Net Operating Income / Cap Rate
amount of money in a bank savings account if one knows the dollar amount of interest and the
interest rate paid by the bank ().
Principal = Interest Dollars / Interest Rate
The Income Approach, therefore, is a Feasibility Study which guides investor decision making.
It advises:
?An investor cannot pay more than ?Value? and still meet the investment goals of the
typical investor (a component of the market-driven Capitalization Rate in the models).?
The Income module will divide each parcel?s estimate of total value into Land Value, Building
Value, and OBY Value as follows:
Total Value (via the Income Approach)
less Land Value (via the CALP module)
less OBY Value (via the Cost module)
Building Value (via the Income Approach)
Residual Land is that part of a parcel?s land area that is not currently engaged
Business Rule:
in generating income for the owner. The appraiser must identify all such land and use the
appropriate Land Code in the CALP module to describe such ?inactive? land.
If the estimate of Total Value for a given parcel (via the Income Approach) is
Business Rule:
less than the land value for that parcel via the CALP module, the appraiser must carefully check
and adjust all components of the Income and CALP modules.
Page 14New Hanover County Tax Office
Should the Income module?s Total Value remain equal to or below the estimate of land value
after close review, the structure(s) on the land will represent an economic mis-improvement to
the land. The appraiser will apply sufficientFunctional Obsolescence to recognize the existence
of the improvements with a residual value (and very carefully note the reason).
INTERFACE

Webster?s Collegiate Dictionary
As used in these Appendices, ?interface? means a collection of computer screens that enable the
end user to view, understand, and maintain data in IAS (the public will have inquiry-only access).

Appendix 2 - GlossaryPage 15
LAND
The name of the ORACLE table that stores Land Line data for the CALP module.
LAND LINE
The computer assisted land pricing (CALP) module of the CAMA system allows the appraiser to
use multiple ?descriptions? to describe the land of any given parcel. Such a description is called
a Land Line. For example, the typical house and its lot only require one Land Line to fully
describe the lot. Alternately, a farm may require twenty Land Lines to fully describe the row
crop areas, the ?high? wooded areas, the pasture lands, and the swampy areas.
LIFE NEW
The day a building is completed is the day it begins to age. Like our bodies, the building will
reach the end of its life in an unknown number of years. Unlike our bodies, a building is said to
have an economic life. That is, most buildings must continually justify its existence to an aware
and knowledgeable owner or it will be removed from the land - regardless of age or condition.
If we think for a moment, we can all remember buildings in good condition that have been razed
or moved to prepare the land for a new use. Conversely, we all know of buildings that have
"lived" for centuries.
Since an appraiser's crystal ball is increasingly fuzzy into the future, the LIFE NEW of any
building cannot logically be projected beyond a few score years. YES, with normal maintenance
any given building will physically last longer - but at the outset one cannot predict the new
building's neighborhood's life cycle or changes in general land use patterns for the long term.

The Map ID is:
NNNNNN.NN.NNNN.NNN
Where: = The TILE or MAP Number for maps printed from the GIS system;
NNNNNN

for each parcel, whether it sold or not.
Sales prices, therefore, are used as a substitute for market value in sales ratio studies and other
analytical work. However: ?One sale does not make a market?. When appraising or appealing
individual properties any subject sale (the sale of any appraised parcel) must be one of at least
three sales used to analyze the property. This will help clarify whether the purchaser in a subject
sale paid too much or too little (got a good deal).
MARKET (Sales Comparison) APPROACH
The Market Approach is one of three methods appraisers may use to estimate value (not every
parcel is a candidate suitable for using all three methods). Also see COST and INCOME.
The Market Approach estimates the total value of a given parcel by analyzing sales of similar
property and adjusting for differences between the sale and the subject. Each parcel in the county
is a ?subject? for the Market Approach. Because the sale price of the comparable property is
known while the market value of the subject is not known (until the conclusion of the analysis),
the appraiser always adjusts the to the and never vice versa.
sale pricesubject parcel
The correct mathematical direction for each such adjustment is revealed by the sentence:
superior
This sale isequalto the subject.
inferior
If an attribute of the sale is superior to the subject in some way, a downward adjustment of the
sale price is appropriate to ?equalize? sale and subject. Likewise if an attribute of the sale is
inferior to the subject, an upward adjustment of the sale price is appropriate. For example,
assume the sale of a residence has a fireplace while the subject has none. The appraiser must
alwaysreduce the sale price to account for the contribution of that fireplace.
Of course, if an attribute of the sale is equal to that of the subject, no adjustment is needed.
The Market module will divide each parcel?s estimate of total value into Land Value, Building
Value, and OBY Value as follows:
Total Value (via the Market Approach)
less Land Value (via the CALP module)
less OBY Value (via the Cost module)
Building Value (via the Market Approach)

MARKET VALUE
N.C.G.S. 105-283 "All property ... shall as far as practicable be appraised or valued at its true
value in money ... the price estimated in terms of money at which the property would change
hands between a willing and financially able buyer and a willing seller, neither being under any
compulsion to buy or to sell and both having reasonable knowledge of all the uses to which the
property is adapted and for which it is capable of being used...?
Specifically to address the requirement to appraise all real property equitably, our goal is to
appraise all properties in New Hanover County for market value.

MASS APPRAISER
A mass appraiser is charged with the responsibility to appraise all parcels in a jurisdiction,
usually for ad-valorem taxation purposes. One major difference between the MASS appraiser
and the FEE appraiser is the amount of time available to appraise each individual parcel.
A second major difference arises from the fact that equity between appraisals is critical for the
MASS appraiser. A FEE appraiser does not usually have to consider any previous appraisal
work when estimating the value of a given parcel.
MILLAGE RATE
The root of the word is the Latin word (thousand). Please see .

MIS-IMPROVEMENT
A structure that can be clearly demonstrated to be in conflict with the of
Highest and Best Use
the land. An example is a house on land zoned for ?high density? commercial use (and located in
a neighborhood where such land is scarce).
The Highest and Best Use of vacant land is dictated by the permanent zoning
Business Rule:
(or with the existence of temporary zoning-in-force, by the most likely permanent zoning) in force
on the Effective Date of Appraisal. A property may be considered as under temporary zoning if
the use of the land is tightly restricted to only one named use and owner is required to go
through the entire re-zoning process to put the parcel to any other use.
Land rates in the neighborhood are best estimated by analyzing sales of similarly zoned vacant
land in the same neighborhood, or a highly similar neighborhood
.
For mass appraisal purposes, the present use of improved land is considered to
Business Rule:
be the Highest and Best Use, except where the present use is in conflict with permanent zoning in
force on the parcel.
A clear example is a residential structure, used as a residence, on land zoned for commercial use
and in an area of predominantly commercial uses. Such non-conforming uses are generally
permitted under zoning regulations and where not permitted, the use is ?grand fathered?.
However continued use as a residence is clearly not the Highest and Best Use of the property.
Page 18New Hanover County Tax Office
Appraise the land of such property for its Highest and Best Use as though vacant (see Business
Rule #1). Appraise the structure according to its contribution, but considering its non-
conforming use (which usually means applying significant Locational Obsolescence). And
always leave clear notes regarding your reasoning in the file.
In cases where the Income Approach clearly demonstrates that a commercial or
Business Rule:
industrial building(s) is a mis-improvement to the land, the existence of the building(s) must be
recognized by placing a sound value (a residual value) on the individual building.
MIXED COMMERCIAL / RESIDENTIAL
This is a commercial building STRUCTURE which is for a two to four story building that houses
retail or office space on the lower floor(s) and has residential space on the upper floor(s). The
preponderance of any income stream arises from the building?s commercial uses. This code has
an influence on the Cost Approach, and the Income Approach. Also please refer to the
discussion of Net Operating Income below.
MIXED RESIDENTIAL / COMMERCIAL
This is a commercial building STRUCTURE which is for a five or more story building that
houses retail or office space on the lower floor(s) and has residential space on the upper floor(s).
The preponderance of any income stream arises from the building?s residential uses. This code
has an influence on the Cost Approach, and the Income Approach. Also please refer to the
discussion of Net Operating Income below.
MODEL
Appraisal management will determine what the county?s most common types of residential and
commercial/industrial structure are. As management further researches the most common
characteristics for each type of structure and estimates ?cost rates? for each type, it becomes a
?model? for the appraisal software to use in appraising all structures via the Cost Approach.
Likewise the Market Approach and the Income Approach both work by a process of modeling
the market.
A ?model? is NOT a builder?s ?model home? for a given subdivision.
MULTIPLE REGRESSION
(Mathematical or statistical) ?regression in which one variable is estimated by the use of more
than one other variable.? Multiple regression is a tool of the CAMA
Webster?s Collegiate Dictionary
module used to indications of market value via the Market Approach where sufficient sales exist.
NEIGHBORHOOD
?A portion of a larger community, or an entire community, in which there is a homogeneous
grouping of inhabitants, buildings, or business enterprises. Inhabitants of a neighborhood usually
have a more than casual community of interest and a similarity of economic level or cultural
background. Neighborhood boundaries may consist of well-defined natural or man-made

barriers or they may be more or less well defined by a distinct change in land use or in the
character of the inhabitants.?

Neighborhood: APPRAISAL AREAS and Neighborhood MODELS
Neighborhood Code is an eight byte, alpha-numeric code. However, the past appraisal system
dictated a four byte, numeric only code. That practice continues, but neighborhood codes may be
expanded as needed. There are seven appraisal areas, loosely defined as follows:
th
Area 0:, Smith Creek to Dawson, Cape Fear River to 17 Street

(Neighborhood Codes = 0001 through 0999);
th
Area 1: , Smith Creek to Monkey Junction, 17 Street to Eastwood-College Roads

(Neighborhood Codes = 1001 through 1999);
Area 2:, Smith Creek and US 17 to Castle Hayne; Pender to Pender

(Neighborhood Codes = 4000 through 4999);
Area 5:East side of , near Snow?s Cut to Oleander Drive, Bradley Creek
Masonboro Township
to College Road (Neighborhood Codes = 5001 through 5999);
Area 6:, follows ?commercial? zoning districts as they occur throughout the county
Commercial
(Neighborhood Codes = 6001 through 6999).
In addition:
Area 7: projects, residential and commercial (Neighborhood Codes = 7000
Condominium
through 7999 with the second byte reserved for Appraisal Area)
Area 8: projects, residential and commercial (Neighborhood Codes = 8000 through
Townhome
8999 with the second byte reserved for Appraisal Area)
Appraisal Sub-Areas:
The second byte of Neighborhood Code further defines the parcel?s location within the appraisal
area.. For commercial neighborhoods, this second byte indicates the neighborhood?s ?township?.
For example Neighborhood 6302 is the second commercial neighborhood in Area 3 while
Neighborhood 7214 is the fourteenth condominium project in Area 2, etc.
Neighborhood Models:
For simplicity in valuing land and to constrain searches for comparable sales, the staff carefully
Page 20New Hanover County Tax Office
groups collections of similar neighborhoods into ?neighborhood models?. The Model Code is a
four byte, numeric only code.
The first two bytes of the Neighborhood Model Code will generally (but not always) indicate
which Appraisal Sub-Area the similar neighborhoods are in. If a given neighborhood is more
like neighborhoods in an adjoining Sub-Area, the appraiser is free to follow the market.
In the third byte of the Neighborhood Model Code (fourth byte for commercial neighborhoods),
the appraisal staff has inserted a code that indicates the relative ?hotness? of the group of
neighborhoods in the market, as follows:
0 = Ocean(neighborhoods bordering the ocean)
1 = Sound( ? ? ? sound)
2 = Creek ( ? ? ? a salt-water creek)
3 = River ( ? ? ? the Cape Fear River)
4 = Golf( ? ? ? a Golf Course)
9 = ?A?(most desirable, non-recreational group of neighborhoods)
8 = ?B?(next most desirable ? grouping)
7 = ?C?( ? ? ? ? ? )
6 = ?D?( ? ? ? ? ? )
5 = ?E?( ? ? ? ? ? )
For residential models, the appraiser is free to use the fourth byte to distinguish one group of
neighborhoods of equal ?hotness? from another. For commercial models, the ?hotness? indicator
already occupies the fourth byte of the Model Code. In the rare case that two groups of
commercial neighborhoods of equal hotness need to be separated, the appraiser is free to use the
third byte (which usually indicates the Appraisal Sub-Area) to create a unique model.
Neighborhood: BROCHURE (Folder for Models and Neighborhoods)
Believing the real estate market is very local in nature, appraisal management has made no mass
appraisal decisions that are county wide in nature. Such decisions are local to the Neighborhood
or the Neighborhood Model. As the appraiser groups neighborhoods into models and makes
such local decisions as land value rates and the change in value due to one or another condition,
the decision must be recorded and placed in the neighborhood?s brochure (folder).
Neighborhood: LIFE CYCLE
?The life of a neighborhood, usually involving the following stages, varying only in intensity and
duration: (1) ; (2) ; and (3) . ?This
Development and GrowthStabilityTransition and Decline
pattern may be followed by renewal and rehabilitation, at which point the cycle is repeated.?

This is a commercial building STRUCTURE and USE which is for retail space with anchor store
space designed into the center BUT the center has lost its anchor store(s). The anchor space is
unoccupied, or has been converted to secondary use. This code has an influence on the Cost
Approach, and the Income Approach. Also please refer to the discussion of Net Operating

NET OPERATING INCOME (NOI)
An investor in commercial real estate is constantly judging the ,, and of

NON-CONFORMING USE
A grand fathered or other use of real property which is not permitted under current zoning
regulations or under a special use permit. See MIS-IMPROVEMENT.

PARCEL
One individually appraised unit of real estate. A parcel may be a vacant lot, a lot with house, the
General Electric, a viable farm, or a 700 acre tract of land awaiting development.
PARCEL ID (PID)
A unique number which identifies a parcel, originally formulated for the original county maps
(on Mylar). This is the identifier used by the appraisal staff and much of the public (although it
has little meaning in defining the location of a parcel). For real estate parcels, the Parcel I.D. is:
R0NNNN-NNN-NNN-NNN
Where: = The Map or Sheet Number from the old Mylar maps;
R0NNNN
= The BLOCK Number given on the old Mylar maps;
NNN
= The LOT Number (within block number);
NNN
= The SUBLOT Number (within lot number).
NNN
In New Hanover County, the Land Department maintains all real estate maps, ownership, and
Parcel I.D. numbers. Since the county moved to the GIS system Parcel ID is a secondary
identifier, except that Parcel ID continues to be the key to the maps used by the appraisal staff.
See MAP ID.

PARTIAL CORRELATION
The partial correlation is a measure of how closely the value of the independent variable or factor
(such as the number of full baths), is related to the dependent variable (usually the sales price).
The dependent variable is adjusted so that all of the other factors in the model are ?taken out? of
the values in order for us to have a measure of how closely this particular variable is related to
the remaining dependent variable. Mathematically, its maximum value is one.

Many structures whose construction begins in the Fall will be incomplete on January 1, yet the
labor and materials thus assembled will contribute to the value of the parcel . This building-level

PERMIT
The name of the ORACLE table that stores building permit data.
PHYSICAL DEPRECIATION
Loss in value due to physical deterioration of the structure.
There are two classes of Physical Deterioration:
1.Curable; and
2.Incurable.
Depreciation schedules for Physical Incurable Depreciation, which reflect the real estate market's
estimate loss in value of the bone structure of the building, are in Appendix 5. These
depreciation schedules are preliminary and may change as appraisal management calibrates the
rate ranges in Appendix 5 to the market in New Hanover County. The appraiser must calculate
and enter Physical Curable Depreciation as an additional percentage in the Functional
Obsolescence field and must list each item of Physical Curable Depreciation together with the
item's cost-to-cure directly into the NOTE fields.
Also see DEPRECIATION, FUNCTIONAL OBSOLESCENCE, ECONOMIC OBSOLESCENCE.
PLUMBING FIXTURE
A plumbing fixture is an opening in a wall which allows an appliance access to a water supply
line and water or sewer drain line. ?Fixture? includes the appliance that is permanently attached
to the building (a clothes washing machine and its connections do not qualify as a fixture).
PRINCIPLES OF VALUE
?The following principles, which have evolved from economic doctrine, form the foundation for
the concepts of value and highest and best use. These principles rarely, if ever, can be considered
in isolation. They should be perceived as interrelated, for they complement and accompany one
another (see Figure 2.3). Also, should be viewed not as an economic
highest and best use
principle or an isolated concept, but as the interrelationship among the basic appraisal
principles.?
The above paragraph, Figure 2.3, and all following ?principle definitions? are quoted from
International Association of Assessing Officers, 1966
Property Assessment Valuation,
Page 24New Hanover County Tax Office
PRINCIPLE OF ANTICIPATION
?Value is the present worth of all the anticipated future benefits to be derived from a property.
The benefits, in the form of an income stream or amenities, are those benefits anticipated by the
market. The assessor should not allow personal opinion to influence the estimation of
anticipated future benefits. Prior sales and prior income streams are important only when they
parallel the current actions of buyers, thus providing an indication of what may be expected in
the future. The is related to the , which can
Principle of Anticipation Principle of Change
sometimes make the prediction of future benefits difficult.?
PRINCIPLE OF BALANCE
?Thehas one meaning when applied to an individual property, and another
Principle of Balance
when applied to neighborhoods. When applied to an individual property, the principle states that
maximum market value is reached when the four agents of production attain a state of
equilibrium. The four agents of production are:
?land
?labor
?capital
?management(coordination).
Appendix 2 - GlossaryPage 25
?Stated another way, balance means that the highest market value will result when the size and
type of improvements are proportional to each other as well as to the land. For example, a three-
car garage is out of balance with a two-bedroom house.
?When applied to a neighborhood, the indicates that maximum market
Principle of Balance
value is reached when the uses of land are perfectly complementary. For example, a single
family residential neighborhood requires commercial facilities such as grocery stores, gasoline
stations, and drugstores. The neighborhood also needs facilities such as churches, schools, and
recreational facilities. The neighborhood and individual properties achieve maximum market
value when these complementary uses are in balance.
?Balance can also be related to the When the
Principle of Increasing and Decreasing Returns.
four agents of production are in equilibrium (balance), the maximum market value is achieved.
Investing more (or withdrawing) any of the agents of production will result in decreasing returns.?
PRINCIPLE OF CHANGE
?This principle states that market value is never constant because environmental (physical),
economic, social, and governmental forces are at work to change the property and its
environment. When these forces are in balance, the market achieves a temporary state of rest
called equilibrium. However, this state of rest does not last because aging and natural events,
such as drought or flooding, change property over time. Thus, the estimate market value is valid
only on the day it is made. The is related to the
Principle of Change Principle of Anticipation
and can affect the prediction of future benefits.?
PRINCIPLE OF COMPETITION
is created by the potential for profits, which attract new sellers and buyers to a
?Competition
market. Competition among sellers may lead to an oversupply, which reduces prices and
profits.? ()
Profits breed competition, excess profits breed ruinous competition.
?Competition among buyers may lead to shortages, which increase prices and profits to sellers.
Applied to property, competition means that an excess of one type of facility will decrease the
value of all such facilities. A neighborhood can support only so many bowling alleys,
department stores, gas stations, and shopping centers. Excess competition destroys balance.?
PRINCIPLE OF CONFORMITY
?The value of property depends, to some extent, on its relation to its surroundings. The
Principle
states that maximum market value is reached when there is reasonable similarity
of Conformity
among the improvements in a neighborhood, and when the residents have similar ages, incomes,
education, attitudes, and so on. The works in conjunction with the
Principle of Conformity

Principles of Progression and Regression
Page 26New Hanover County Tax Office
PRINCIPLE OF CONSISTENT USE
?Thestates that the property must be value with a single use for the
Principle of Consistent Use
entire property. It is improper to value a property on the basis of one use for the land and another
use for the improvements. This principle is especially important to remember when valuing a
property in transition from one use to another. For example, a residence situated on a parcel that
is zoned and surrounded by commercial property may have a remaining physical life. However,
its economic life may have already ended. In this case, the improvements may have negative
value, namely, the cost of demolition.?
PRINCIPLE OF CONTRIBUTION
?The states that the value of a component of property depends upon its
Principle of Contribution
contribution to the whole. In other words, the cost of the component does not necessarily equal
the value the component adds to the property. For example, a residential homeowner spends
$7,500 to erect a garage. However, the market value is increased by only $5,000. In this case,
$5,000 is the value contribution to the garage.
?In the case of income-producing properties, the value of a component can be measured by the
amount it contributes to net operating income, because net operating income can be capitalized
into value. For example, the owner of a small retail store finds that by spending $6,000 for an
air-conditioning unit, annual gross income from rents can be increased by $1,800. Additional
operating expense due to the air-conditioning unit will be only $1,200, including amortizing the
investment. Thus, installing this unit will add value in excess of cost.
?Another situation that occurs, especially in areas experience in transition, is that the existing
improvement does not provide a proper balance for the total property, because the current use
does not fully utilize the land. However, this interim use may continue until it is economically
feasible for someone to convert the property to a use that does fully utilize the land. Thus, the
assessor must estimate the correct value contributed by the improvements to the property as a
whole.
?The is the basis for the adjustment process in the sales comparison

obsolescence are curable or incurable (see chapter 8); and for justifying remodeling and

Appendix 2 - GlossaryPage 27
PRINCIPLE OF INCREASING AND DECREASING RETURNS
?The states that when successive increments of
Principle of Increasing and Decreasing Returns
one agent of production are added to fixed amounts of the other agents, future net benefits
(income or amenities) will increase up to a certain point (the point of decreasing returns) after
which successive increments will decrease future net benefits. For example, assume an investor
is deciding how much capital to invest in constructing a commercial building. The investor?s
analysis provides the following returns on different amounts of investment:
?a $500,000 building will earn a 1.4 percent return;
?a $600,000 building will earn a 5.5 percent return;
?a $700,000 building will earn an 8.0 percent return;
?an $800,000 building will earn a 5.8 percent return;
?a $900,000 building will earn a 1.2 percent return.
?Additional investment of capital produces increasing returns up to the point of $700,000 in this
illustration. Beyond this point, the return on additional capital diminishes. The

PRINCIPLES OF PROGRESSION AND REGRESSION
?The states that the value of a lower priced property is increased by

association with better properties of the same type. For example, a $90,000 house among
$140,000 home could probably bring a price higher than $90,000 in the market. The
Principle of
states that the value of a better quality property is decreased by association with lower

quality properties in the same area. Thus, when a $120,000 house is located in an area where the
typical home is about $70,000, the market value of the former will tend to fall. The $120,000
house in this example is an overimprovement for the neighborhood. The
Principles of

Progression and Regression Principle of Conformity
PRINCIPLE OF SUBSTITUTION
?A property?s market value tends to be set by the cost of acquiring an equally desirable and
valuable substitute property, assuming that no costly delay is encountered in making the
substitution. This principle underlies each of the three approaches to value- cost, sales
comparison, and income.?
PRINCIPLE OF SUPPLY AND DEMAND
?The theory of , as applied to property appraisal, holds that the price of a
supply and demand
property varies directly with demand and inversely with supply. In the market, sellers can control
supply and price to influence demand. By failing to produce enough of a product to meet
demand, sellers can raise prices. By raising prices, sellers can decrease demand. Buyers can
influence price and supply by staying out of the market until prices decrease, which often
happens when supply increases in relation to demand. Many forces, environmental (physical),
Page 28New Hanover County Tax Office
economic, social, and governmental, influence the behavior of buyers and sellers.
?... Supply is a function of the four agents of production: land, labor, capital, and management.

PRINCIPLE OF SURPLUS PRODUCTIVITY
?Surplus productivity is the net income remaining after the costs of labor, management, and

QUALITY GRADE
Quality Grade is the appraiser's notation of the quality of original materials and workmanship in
a structure. Care should be taken to avoid confusion between ORIGINAL QUALITY and
OBSERVED CONDITION and LOCATION.
By strict appraisal definition the above three terms are not interrelated. The real estate market
interrelates them, but when listing or reviewing parcels the appraiser must not be confused. The
following box illustrates the separateness of these ideas and definitions.

R SQUARED
Thestatistic is a ratio related to how well the data (sale prices) are fit by the regression

equation. It is equal to the complement of the residual sum of squares divided by the total sum of
squares corrected for the mean, where the total sum of squares is the sum of the squares of the
sales prices minus their mean value, and the residual sum of squares is the sum of the squares of
the differences between the actual sales prices and those predicted by the regression equation. It
is apparent that the closer is to 1, the better the ?fit? of the data.

RECREATIONAL CENTER
This is a commercial building USE which is for recreational space including but not limited to
health club, bowling alley, and skating. This code has an influence on the Cost Approach, and
the Income Approach. Also please refer to the discussion of Net Operating Income above.
REMAINING ECONOMIC LIFE
The day a building is completed is the day it begins to age. Like our bodies the building will
reach the end of its life in an unknown number of years. Unlike our bodies, a building has an
economic life. The building must continually justify its existence or it will be removed from the
land - regardless of its physical age or condition.
TheRemainingEconomicLife (REL) is the appraiser's estimate of the amount of time the
building will continue to justify its existence. Remaining Economic Life has a converse
relationship with Effective Age. Therefore, as a building ages, Remaining Economic Life
becomes easier to estimate and the Effective Year Built (Age) becomes harder to estimate.
This may be directly observed in the following "formula".
Life New = Effective Age + Remaining Economic Life
This formula will always contain a true statement. Life New is a stable, unchanging "constant"
value in the formula (it is the estimate of a NEW building's life). Effective Age and Remaining
Economic Life are mathematically "complementary" numbers. That is, Life New always stays
the same while Effective Age must change if Remaining Economic Life changes, and vice versa.
Also see EFFECTIVE AGE, DEPRECIATION and LIFE NEW discussions.
REPLACEMENT COST NEW
One of two basic concepts within the Cost Approach, Replacement Cost New strives to reflect to
cost to replace the function of a building rather than the cost to reproduce the building itself.
This concept lends itself to mass appraisal much better than the concept of Reproduction Cost
New because it does not reproduce the functional problems that older buildings tend to exhibit.
In mathematically replacing the function of a building rather than the building itself, items of
functional obsolescence (such as excessive or over-built foundations) are NOT introduced into the
pricing algorithm. Such Functional Obsolescence actually existing in a given building must NOT
be recognized or the appraiser will "kick the dog twice" (or remove the item twice). See RCN.
RESIDENTIAL (ON) COMMERCIAL LAND
There are five codes intended to be used to appraise residential buildings via the commercial cost
approach algorithm, as backed up by the Income Approach. They are:
RCLResidential on Commercial Land - Use for structures having non-residential uses.
R1F, R2F, R3F, and R4FUse where multiple residential structures on one parcel are used for
Appendix 2 - GlossaryPage 31
residential purposes.
Residential appraisers will use these codes (and thereby,
Business Rule:
the commercial algorithms) to appraise multiple residential buildings on residential land.
RESIDENTIAL TIMESHARE
?Joint ownership or rental of a vacation lodging (as a condominium) by several persons (or
entities) with each occupying the premises in turn for short periods.?
Webster?s Collegiate Dictionary
When a timeshared property is viewed as a whole and under the operational
Business Rule:
management of one entity that is the de facto property manager / agent for all time-owners, all
rights of ownership, to include possession, are viewed as being intact asrepresented by that
entity. Therefore the Tax Administrator?s Office will appraise each such property as a whole,
under one Parcel ID, for fee simple market value. The management company will have sole
responsibility to apportion the resulting annual tax liability among the several time-owners.
RESIDUAL LAND
The IAS CAMA module reserves a specific meaning for the term ?Residual Land?. It is that part
of a parcel?s land area that is not currently engaged in generating income for the owner.
Residual
may share road frontage with the portion(s) of the land that are generating income. As such
Land
and from time-to-time true ?residual? land may have a ?For Sale or Lease? or ?Build to Suit?
sign on it.may also be ?rear? land available for (but not yet under) a separate use.

ROLL
Different types of property are commonly grouped together for ad valorem taxation. Real Estate,
Personal Property (air planes, machinery and equipment, etc.), Intangible Personal Property (cash
in bank accounts, stocks, etc.) are all examples of different tax rolls. New Hanover County has a
?Combined Roll?, meaning Real Estate (land, building(s), and miscellaneous improvements) may
easily be combined with Personal Property items (boats, automobiles, etc.) on any tax bill.
ROOF PITCH
The ?pitch? of a roof measures the angle between the eave of the roof and the crown of the roof,
and is expressed as a ?rise and run? fraction. For example, if a roof has a 6:12 pitch, it will rise
six feet for every twelve feet of run (or six inches of rise for every foot of run).
The typical residential roof (without dormers) must have a minimum 6:12 pitch to have enough
usable attic space to call the 1.25 story. Of course, there will always be exceptions

SALES RATIO STUDY
A Sales Ratio Study is the tool we use to test the Cost Approach appraisal product of the County,
the annual Tax Roll. This measures the performance in the interaction of land values, building
data elements (or characteristics), and the rates in the User Control Tables. The Cost Approach
is the default method of valuing each parcel in the County.
A sales ratio is calculated by dividing the appraised value of a given parcel by the sale price of
the parcel. For example, if a parcel is appraised for $80,000 but sold for $100,000, the sale ratio
is .80 (or 80%).
A sales ratio study is a statistical analysis of all sales ratios in the sample. The ratio study advises
at least two critically important facts:
1.The level of appraised values as compared to sale prices;
For example, a median ratio of .97 indicates that parcels are generally appraised for 97% of
sale price.
2.The tightness of fit of the ratios in the sample about the median sales ratio.
The Department of Revenue measures uniformity with the Coefficient of Dispersion (COD).
The lower the COD number, the more uniform the values in the Tax Roll are.

SQRT
Square Root (of a number) as used in certain formulas in the CAMA module.
SOUND VALUE
An appraiser's estimate of the residual value for an improvement that has reached the end of its
economic life. As long as the improvement exists, it cannot be legally removed from the Tax
Roll (exempted from taxation) unless it is so far gone that it literally contributes no value to the
parcel. (In these cases, the appraiser must describe the item sufficient to identify it and note that
it existed on a date certain.) Sound Values are quite low and are used to merely recognize the
existence of the improvement as of January 1 of the year in question, the TAX DATE.
STANDARD ERROR
The square root of the gives an idea of the average amount by which
mean square residual
regression equation ?misses? actual sale prices. In a somewhat more precise statistical sense, we
expect that roughly 2/3 of the regression estimates should be within one standard error (either
high or low) of the actual sales price. In general, the smaller this number the better.
(Residential Only)
STORY HEIGHT
For residential buildings, the story height for each section of BASE area is entered in quarter
story sizes, from 1.00 story to 4.25 stories
Generally, the residential appraiser selects the appropriate story height for a building according to
the amount of area available in the upper floor areas as compared to the amount of BASE area in
the ground floor. For example:
_.00 Story =Less than 20 % usable area (?stick-built?, for attic living space).
_.25 Story =20% to 40% usable area (?stick-built?, for attic living space).

STRATIFICATION
The process of segmenting, or layering, the appraisal database.
Ratio studies available to New Hanover County enable us to study the entire county or a portion
of the county. For example, sales may be restricted to sales of residential buildings that are of a
certain age AND to buildings that are also 300.
Quality Grade
This enables us to seek common weaknesses in the appraisal product and correct them - before
Notices of Value for a given year are mailed. Appendix 2 presents a detailed discussion of
STRATIFICATION.
STRIP RETAIL CENTER
This is a commercial building USE which is for retail space in a complex designed without
anchor store space. This code has an influence on the Cost Approach, and the Income Approach.
Also please refer to the discussion of Net Operating Income above.
STRUCTURE
This is a required field for commercial buildings. It defines the purpose for which the building
was designed and built, which may or may not be the present use of the building.
The Structure code is an element of the Replacement Cost New of the building.
T STATISTIC
The is a ratio of the of a coefficient to the value of that coefficient.

TABLE (Database)
A table in a database contains data arrayed in rows and columns, just like a typical Excel or Lotus
spreadsheet. The table?s rows contain data while the columns organize the data (each column
contains the same type of data). Each column header names the data stored therein. For
example Parcel ID, a basic way of relating parcel-level data housed in different tables, is always
stored in a table column named PARID. No other kind of data will ever be found in this column.

Page 36New Hanover County Tax Office
prejudice for the county or any owner therein.
TAXABLE VALUE
The net result of subtracting the value of any exemptions from the Market Value or Use Value.
This is the value used to calculate the annual tax bill.
TAX DATE
N.C.G.S. 105-285 mandates that property ownership will be kept, and parcels are to be appraised
as of January 1 each year.
For example, John Smith purchased a house on September 10, 2006. He is NOT the owner-of-
record on the 2006 tax bill, but since he owns it on 01/01/2007 he will be the owner for 2007.
The appraised value of John Smith's house will also reflect our opinion of the property's value as
of January 1 of each of these years. If Mr. Smith adds a porch immediately upon purchase
(finishing by December 31) he will also see a change in value (for 2007) on his 2007 Notice.
TAX DISTRICT
A given property in New Hanover County receives a given set of services from the County
according to its location. "Tax District" is the term given to an area where governmental services
are identical, so the parcels in each district will pay the same Millage Rates for those services.
See MILLAGE RATE.
(or Tax Scroll)
TAX ROLL
A ?Tax Roll" or ?Scroll? is a listing and summing of all taxable property in New Hanover
County as broken into classes of property (Property Class is an entry on the ASMT screen).
?Tax Roll? or ?Scroll? is a North Carolina-specific term synonymous with Digest, Grand List, et
cetera, used in other states.
TIMESHARE
See RESIDENTIAL TIMESHARE
UNIT OF COMPARISON
For a real estate appraiser, it is often times more meaningful to work with Units of Comparison
rather than a whole number, such as a sale price or appraised value. For example, the sale price
per acre of a large vacant parcel is much more applicable to other large vacant parcels than the
whole sale price of the parcel.
Several different kinds of Units of Comparison are important in appraisal work.
For example, appropriate ?units? for land are- the Square Feet of land area, - the Front
?S??F?
Appendix 2 - GlossaryPage 37
Feet along a road, - the Acreage (for larger parcels), or - for ?Unit? (value per lot).
?A??U?
With improvements to land, the appropriate residential unit is the gross square feet of BASE
(living) area. For commercial or industrial buildings, the gross or net square feet of BASE area is
appropriate. For tank farms not charged as personal property, net cubic feet enclosed is
appropriate, while the number of overhead doors (for truck terminals), the number of rooms
(hotels and motels), etc. are also Units of Comparison appropriate for each industry.
USABLE SPACE
Measure the square footage of for all finished attics and bonus rooms and ?dot-in?

ZONING (Permanent)
To appraise a parcel for market value is to assume that all rights of real ownership are
fee simple
intact and vested in the owner-of-record except as limited by the powers of state (as delegated to
local jurisdictions). The zoning-in-force on a parcel limits one of the inherent rights of ownership:
to use the property in any way the owner sees fit. Permanent zoning-in-force recognizes or lists the
various specific uses permitted on parcels enjoying membership in a given Zoning District and,
without question, the owner is free to choose among the several permitted uses.
ZONING (Temporary)
Jurisdictions in North Carolina are permitted to more tightly control the uses an owner may
contemplate for property by allowing only one named use. Generally the temporary use is an
interim use as requested by the owner at the time. If the owner wishes to change the parcel?s
named use to any other use, to include reversion back to the formerly permitted use, the owner
must reapply for a change in Zoning District and go through the entire re-zoning process.
If a given property is clearly in an INTERIM USE (see discussion under this
Business Rule:
topic heading above) and the jurisdiction allows only one named use for the property, the
appraiser must consider the named specific use to be a temporary zoning-in-force. Temporary
zoning will in no manner represent or limit the most likely highest and best use of the parcel.
Appraise land in interim use under temporary zoning-in-force for its most likely
Business Rule:
highest and best use, considering the permitted uses of surrounding and nearby parcels, and the
demand for a change to the most likely highest and best use. The appraiser must recognize: (1)
the cost of re-zoning the parcel; and (2) the holding period, during which the interim use is likely
to continue while market demand increases for the change to the most likely highest and best use.
