What is the purpose of requiring appraisers to maintain workfiles for a specific duration?

The purpose of requiring appraisers to maintain workfiles for a specific duration is fundamentally tied to the principle of transparency in the appraisal process. By preserving detailed records of how an appraisal was conducted—such as the methodologies used, data sources, and decisions made—appraisers provide a clear audit trail that can be reviewed by clients, stakeholders, and regulatory bodies. This transparency not only helps to uphold the integrity of the appraisal process but also builds trust among the parties involved.

While other aspects such as legal preparedness and compliance do play a role in the importance of workfiles, the foundational goal remains the promotion of clarity and accountability in appraisal practices. This is particularly critical in the event of a dispute or review, as having accessible documentation enables better understanding and resolution of issues that may arise.
