What is a mass appraisal?
We are responsible for doing mass appraisal which falls under Standard 6 of “The Uniform Standards of Professional Appraisal Practice”. Even though some of the thought process and terminology is similar, mass appraisal practices are different from fee appraisals practices. A fee appraisal is of a single property as of a given date. In a fee appraisal the quality of appraisal would be measured by comparison with sales of comparable properties during the given time. A mass appraisal is the systematic appraisal of a universe of properties as of a given date. In mass appraisal the focus is not on the individual property. The quality of a mass appraisal is determined by its use of standard methodology, the employment of common data, and the over all subjection to statistical testing. In a reassessment it is our objective to value property at its current fair market value as of the control date of December 31st of the year prior to implementing.
