How does an appraiser determine a property's value?
Appraisers typically apply three approaches to value: the sales comparison approach, which weighs the property against recent sales of similar homes; the cost approach, which estimates replacement cost minus depreciation; and the income approach, which capitalizes expected rental income and is used mainly for investment properties. They verify the legal description in public records, inspect and photograph the property, analyze comparable sales, and then reconcile the approaches to reach a final opinion of value.
Appraisers determine value primarily through the sales comparison approach, which weighs the property against recently sold, similar properties with adjustments for differences. Depending on the assignment, they may also use a cost approach (land value plus replacement cost less depreciation) or an income approach (capitalizing the property's income potential), then reconcile the results into a final opinion of value.

DC law defines appraisal as the process of estimating the value of real property and real estate. The appraiser inspects the site and building, analyzes the neighborhood, determines highest and best use, researches comparable sales, applies income and cost analysis, and reconciles the findings into a value estimate. These are the task areas District trainees must document on the Board's Appraiser Assignment Log.

Appraisers determine value by applying the three standard approaches: sales comparison, cost, and income. The process typically includes a site and building inspection, neighborhood analysis, a highest and best use analysis, comparable sales research, and reconciliation of the results into a final opinion of value. All appraisal work must comply with the Uniform Standards of Professional Appraisal Practice (USPAP).

Appraisers determine value by applying three approaches: comparing the property to recent sales of similar properties, calculating replacement cost minus accrued depreciation, and capitalizing the income the property could produce. They then weigh the results in a written reconciliation to reach a final value estimate. Idaho's Board expects submitted work samples to show all three approaches and at least two sets of paired sales supporting any major adjustment on the sales grid.

An appraiser forms an opinion of value by inspecting the site and the improvements. Outside, the appraiser reviews neighborhood characteristics, zoning, lot size, utilities, and the driveway. Inside, the appraiser reviews square footage, the number of bathrooms and bedrooms, the foundation, the basement, and building materials.

Appraisers follow the Uniform Standards of Professional Appraisal Practice (USPAP), which requires them to be aware of, understand, and correctly use recognized methods and techniques to produce a credible appraisal. The standard approaches covered in qualifying education include the sales comparison approach, the site valuation and cost approach, and the income approach. USPAP sets minimum standards but does not mandate any specific methodology.

Appraisers determine value mainly by comparing the home to recent sales of similar nearby properties, weighing the home's condition and features against those comparables. For FHA appraisals, they must also cite recent comparable sales, recently closed sales in the subdivision, and active or pending listings from the surrounding market.

Real estate appraisers estimate value using three approaches taught in Wyoming's qualifying education: the sales comparison approach, the income approach, and the cost approach, supported by site valuation and by market analysis with highest and best use analysis. Wyoming has adopted the Uniform Standards of Professional Appraisal Practice (USPAP) as the binding state appraisal standard through the Board's administrative rules (Chapter 4).
