REVIEW METHODOLOGY


Our Appraisal Review service involves a detailed analysis of an already-existing appraisal, focusing on key aspects such as:

  • Completeness
  • Appraiser's Qualifications
  • Adequacy and Relevancy
  • Appraisal Methodology
  • Credibility
  • USPAP Compliance
  • State and Federal Compliance
