When must a written summary of an oral appraisal report be added to the appraiser's workfile?

The correct response emphasizes the importance of maintaining accurate records and upholding the profession's standards. A written summary of an oral appraisal report must be added to the appraiser's workfile within a reasonable time after the issuance of the report to ensure that all relevant and essential information is documented properly. This helps maintain the integrity of the appraisal process and allows for future reference, which is critical for compliance with USPAP standards, particularly in the context of documenting the appraiser's thought process, methodologies, and the conclusions reached.

Maintaining a written summary helps assure that if questions arise later regarding the appraisal, all pertinent details are readily available. This requirement aligns with best practices in the profession and reinforces the necessity of clear, concise documentation as part of the appraiser's responsibilities.
