STANDARD 6: MASS APPRAISAL, DEVELOPMENT AND REPORTING

Comment: STANDARD 6 applies to all mass appraisals of real or personal property regardless of the purpose or use of such appraisals.(note62)  STANDARD 6 is directed toward the substantive aspects of developing and communicating credible analyses, opinions, and conclusions in the mass appraisal of properties. Mass appraisals can be prepared with or without computer assistance. The reporting and jurisdictional exceptions applicable to public mass appraisals prepared for ad valorem taxation do not apply to mass appraisals prepared for other purposes.

A mass appraisal includes:

1)

identifying properties to be appraised;

2)

defining market area of consistent behavior that applies to properties;

3)

identifying characteristics (supply and demand) that affect the creation of value in that market area;

4)

developing a model structure that reflects the relationship among the characteristics affecting value in the market area;

5)

calibrating the model structure to determine the contribution of the individual characteristics affecting value;

6)

applying the conclusions reflected in the model to the characteristics of the property(ies) being appraised; and

7)

reviewing the mass appraisal results.
 

The JURISDICTIONAL EXCEPTION RULE may apply to several sections of STANDARD 6 because ad valorem tax administration is subject to various state, county, and municipal laws.
