The Uniform Standards of Professional Appraisal Practice (USPAP®) is the generally recognized ethical and performance standards for the appraisal profession in the United States.
In 1987, the Ad Hoc Committee of appraiser membership organizations established The Appraisal Foundation® (Foundation) to implement USPAP® as the generally accepted set of appraisal standards in the United States. These organizations recognized the importance of ensuring that appraisals are based upon established, recognized standards. USPAP® was then authorized by Congress in 1989. It contains standards for appraisal disciplines, including real estate, personal property, business valuation, and mass appraisal. Compliance with USPAP® is required for state-licensed and state-certified appraisers who perform appraisals for federally-related real estate transactions.
The USPAP® standards related to real property development, reporting, and appraisal review, known collectively as Standards 1-4, are referenced by federal financial institution regulatory agencies when implementing Title XI of the Financial Institutions Reform, Recovery, and Enforcement Act (FIRREA).
EDS Appraisal Umpire Services specialists are qualified independent-neutral third-party valuation experts who are appointed to resolve disputes between appraisers who have provided conflicting valuations of a property. The umpire reviews the evidence and findings of both appraisers and makes a final determination of the property’s value. This process is often used in real estate transactions or insurance claims when there is a disagreement about the value of a property.
