Appraiser Jargon

Heard Richard use one of these terms and wondered what it meant? Every profession has its own shorthand — what "res ipsa loquitur" is to a lawyer, "external obsolescence" is to an appraiser. Here's a plain-English guide to the terms that come up most often.

Adjustment
Once comparable properties are identified, the appraiser adjusts the value of the subject property to account for differences in living area, acreage, frontage, amenities, and more. This is where real professional expertise matters most.
Chattel
Personal property that may be on the subject property but doesn't factor into the opinion of value in the appraisal report.
Comparable ("comp")
A property similar to the subject property that has sold recently nearby, used as a basis for determining fair market value. USPAP sets clear guidelines for what qualifies as a comparable.
Drive-By
An appraisal limited to reviewing comparable sales and confirming the property exists with no obvious exterior defects or damage. Fannie Mae's form for this type is the 2055, so you may hear it called simply "a 2055."
Fair Market Value
The appraiser's opinion of value, reflecting what a willing seller would accept from a willing buyer in an arm's-length transaction.
GLA
"Gross Living Area" — the total above-grade floor space, including stairways and closet space, typically measured from exterior wall dimensions.
Latent Defects
A defect that isn't readily apparent but that impacts fair market value — structural damage or termite infestation are common examples.
MLS
Multiple Listing Service — a database of properties on the market, their asking prices, and recent closed sales. Most appraisers pay for MLS access to support comparable selection and adjustment research.
Obsolescence
A decline in value as a feature becomes less desirable, either because it's outdated (functional obsolescence) or because changes in the surrounding area make it less appealing (external obsolescence).
Subject
Short for the property being appraised — "the subject property."
Useful Life
The span of time during which a property can continue to provide benefit to its owner.
URAR
Uniform Residential Appraisal Report, Fannie Mae Form 1004 — the standard form most lenders require for a full appraisal with a walk-through inspection.
USPAP
Uniform Standards of Professional Appraisal Practice — the rulebook that governs professional appraisal conduct, maintained by the Appraisal Foundation and frequently written directly into state law.
Walk-Through
An inspection that includes visiting every part of the home's interior used in estimating value.
