In the context of mass appraisal, what is a major difference from fee appraising?

In mass appraisal, a major difference from fee appraising lies in the incorporation of Statistical Quality Control (SQC). SQC is essential in mass appraisal because it involves assessing many properties simultaneously and ensures that the valuation process adheres to established standards of accuracy and uniformity. By applying statistical methods, mass appraisal can identify trends, mitigate errors, and verify the reliability of property valuations across larger datasets.

This systematic approach allows appraisers to ensure consistent valuation practices that meet regulatory requirements and provide a basis for equitable property taxation. Incorporating SQC helps in maintaining the integrity of the appraisal process, thereby enhancing the overall quality and fairness of mass appraisals as they often rely on extensive data analysis rather than the more personalized, case-specific evaluations typical in fee appraising.
