Which source is expected to provide the most reliable and up-to-date information regarding review appraisal standards?

The current edition of USPAP (Uniform Standards of Professional Appraisal Practice) is recognized as the authoritative source for appraisal standards, including review appraisals. USPAP is updated regularly to reflect changes in policies, practices, and regulatory requirements, ensuring that professionals in the appraisal field have access to the most precise and current standards. The clarity and detailed guidelines outlined in the latest edition make it the go-to source for practitioners seeking reliable information on appraisal standards.

In contrast, while past editions of USPAP provide historical context and might still contain relevant information, they do not reflect the most current practices. The book "Appraising the Appraisal" offers insights and commentary about appraisal processes but is not a formal standard document. Advisory Opinions provide additional guidance but may not encompass the full scope of current review appraisal standards as found in the latest USPAP. Therefore, relying on the current edition of USPAP is essential for ensure compliance and excellence in appraisal reviews.
