An appraiser must disclose any service they provided related to the subject property for a period of how many years prior to performing the appraisal?

The correct answer is that an appraiser must disclose any service they provided related to the subject property for a period of 3 years prior to performing the appraisal. This requirement aligns with the ethical standards set forth by appraisal organizations, including the Uniform Standards of Professional Appraisal Practice (USPAP). The 3-year disclosure window is important because it ensures transparency and helps maintain the integrity of the appraisal process.

By requiring appraisers to disclose prior services for this duration, potential conflicts of interest are minimized, and the credibility of the appraisal is enhanced. Stakeholders, such as clients and regulatory bodies, need to know about any prior involvement the appraiser might have had with the property to assess the objectivity of the appraisal. The approach taken by a 3-year period strikes a balance between ensuring ample disclosure and allowing appraisers to engage in their professional activities without perpetual restraint from past associations.

The other options do not reflect the standard practice and guidelines set forth within the industry, where a 3-year disclosure period has been established as the norm.
