May an appraiser use data from a prior assignment for a different client?

Correct Answer

B) Yes, but confidential assignment results stay protected

Why this is correct: The Uniform Standards of Professional Appraisal Practice (USPAP) and professional ethics distinguish between general market data and confidential client information. Verified sale data and general market knowledge are considered the appraiser's professional expertise and can be reused. However, the specific assignment results, opinions, and any confidential information provided by the prior client remain protected and cannot be disclosed or used for another client's assignment without consent. Why the other choices are wrong: "Yes, all appraisal data becomes public over time" is incorrect because confidential assignment results and client-specific information do not automatically become public. "No, prior files may never inform later assignments" is incorrect because general market data and verified facts are reusable. "No, unless the earlier client grants written consent" is incorrect because it misstates the rule; consent is not required for using general market data, only for confidential assignment-specific information. Exam tip: Remember the key distinction: market facts are reusable; confidential assignment results and client information are not.
