Uniform Standards of Professional Appraisal Practice - Standards Vs. Methods

Standards Vs. Methods

While USPAP provides a minimum set of quality control standards for the conduct of appraisal in the U.S., it does not attempt to prescribe specific methods to be used. Rather, USPAP simply requires that appraisers be familiar with and correctly utilize those methods which would be acceptable to other appraisers familiar with the assignment at hand and acceptable to the intended users of the appraisal. USPAP directs this through what is called the Scope of Work rule. At the onset of an assignment, an appraiser is obligated to gather certain specified preliminary data about the project, such as the nature of the property to be appraised, the basis of value (e.g. market, investment, impaired, unimpaired), the interests appraised (e.g. fee, partial), important assumptions or hypothetical conditions, and the effective date of the valuation. Based on this and other key information, the appraiser relies on peer-reviewed methodology to formulate an acceptable workplan.
