How long must an appraiser disclose their previous services related to a subject property before accepting a new assignment?

The requirement for an appraiser to disclose previous services related to a subject property before accepting a new assignment is set at three years. This standard is outlined in the Uniform Standards of Professional Appraisal Practice (USPAP), which emphasizes the importance of transparency and avoiding conflicts of interest.

When an appraiser has provided services related to a property within the three years prior to the new assignment, it is essential to disclose this information to clients. This requirement protects the integrity of the appraisal process and ensures that all parties are aware of any potential biases or influences that previous work may introduce. By having this three-year disclosure period, USPAP fosters accountability and helps maintain a high level of trust in the appraisal profession.
