Effectively reviewing commercial appraisals requires the appraiser to adhere to detailed procedures and analyses. Not only do real estate appraisers require education and experience to be successful at reviewing appraisals, but a successful reviewer must also have an effective and systematic review strategy for any given appraisal review problem. In this introductory commercial appraisal review course, the presented systematic strategy follows the appraisal process itself. This course also examines the relevant Uniform Standards of Professional Appraisal Practice (USPAP) requirements and introduces tools, suggestions, and tips including the use of CAARR (Completeness, Accuracy, Adequacy, Relevance and Reasonableness). This course includes several illustrations, exercises, and case studies.
