- ValidityThe quality of a data element or procedure being what it should be in terms of some ultimate purpose or use. See integrity. Compare accuracy, precision.
- Valuation(1) The process of estimating the value -- market, investment, insured, or other properly defined value -- of a specific parcel or parcels of real estate or of an item or items of personal property as of a given date. (2) The process or business of appraising, of making estimates of the value of something. The value usually required to be estimated is market value.
- Valuation Acceptance CriteriaCriteria for determining the acceptability of a value estimate generated by a particular AVM. These policies are model-specific and usually consider confidence score thresholds or forecast standard deviations (FSD), as well as the organization’s risk appetite.
- Valuation, AssessedSee assessed value.
- Valuation DateThe specific date as of which assessed values are set for purposes of property taxation. This date may also be known as the "date of finality." See assessment date.
- Valuation MethodA specific process used in a Model that estimates a value for a property.
- Value, ActualMarket value, especially as distinguished from the so-called book, par, or face values.
- Value, CashMarket value in terms of cash.
- Value, ExchangeSynonymous with the preferred term "market value."
- Value, FaceSee face value.
- Value, FullSynonymous with the preferred term market value.
- Value, GoingThe value of an entire property in active service and with an established clientele, as distinguished from its value immediately before being put into service or upon retirement from service.
- Value, ImprovedA loose term generally defined as that portion of the present worth of a property that represents the resale factor. (Term not recommended for use.)
- Value in Exchange(1) The amount an informed purchaser would offer for property under given market conditions. (2) The concept that states value is based on the ability of property to command another asset, such as money, in trade.
- Value in UseThe value of property for a specific use. The concept that holds value to be inherent in property itself, that is, the value is based on the ability of the asset to produce revenue through ownership.
- Value IncrementThe amount by which a property has increased in value. See increment, unearned.
- Value, Intrinsic(1) The value of an article due to its own physical qualities rather than to the rights, privileges, or immunities with respect to other properties or persons which its possession confers. (2) A term used to designate "value" that is supposed to reside within an article rather than within the minds of its actual or would - Be possessors. Note: This is a term that is much abused and that might well be discarded. Although it is proper to say that the intrinsic value of a stock certificate is the value, if any, of the paper, it is not correct to say that real estate has an intrinsic value(...)
- Value, MarketSee market value.
- Value, MoneySynonymous with the preferred term "cash value."
- Value, NormalA loose term used to denote some sort of mean between high and low market prices obtaining over a period of time or in different markets at any moment of time (a term not recommended for use).

- VariableAn item of observation that can assume various values, for example, square feet, sales prices, or sales ratios. Variables are commonly described using measures of central tendency and dispersion.
- Variable CostsThe costs of the variable resources used by a firm in either the short run or the long run.
- Variable Proportions, Law ofAlso called the "law of decreasing returns," this states that as quantities of one productive factor in crease, the quantities of other productive factors remaining fixed, the resulting additional increments of product or output will de crease after a certain point.
- VarianceA measure of dispersion equal to the standard deviation squared.
- Variation(1) A general term meaning dispersion. (2) A reference to a particular statistic called the coefficient of variation.
- VerifyTo check the accuracy of something. For example, sales data may be verified by interviewing the purchaser of the property, and data entries may be verified by check digits.
- Vertical InequityThe tendency of an AVM to value high-value properties differently than low-value properties in relation to their selling prices. Can be measured by PRD or PRB.
