Delta Mass Appraisal Services, Inc. is a State of Arkansas approved mass appraisal contractor. Mass appraisal is the systematic appraisal of groups of properties as of a given date using standardized procedures and statistical testing. This differs from single-property appraisal, commonly referred to as "fee" or "bank" appraisal, which normally deals with only a particular property as of a given date.
Mass appraisal includes the application of single-property appraisals, as well as the development of appraisal formulas and statistical models, that can be applied uniformly to a number of properties at a time.
