A valid appraisal practice requires an appraiser to avoid:

The correct answer emphasizes the importance of avoiding conflicts of interest to ensure the integrity and impartiality of the appraisal process. Although disclosing any personal interest in a property is a step taken to maintain transparency, it does not eliminate the potential bias that could arise when an appraiser has a vested interest in the property being appraised. A valid appraisal must be objective and independent, aiming to provide an unbiased opinion of value.

Accepting an appraisal fee for a property in which the appraiser has an interest, even with disclosure, could undermine the credibility of the appraisal and lead to ethical concerns. Appraisers must maintain a clear boundary to prevent any perception of impropriety and uphold the standards of their profession.

In contrast, while accepting assignments without proper qualifications can lead to a lack of competency and may jeopardize the quality of the appraisal, it still centers around the appraiser's qualifications rather than conflicts of interest. Charging referral fees and paying for client referrals raise ethical concerns as well but are framed differently than merely having an interest in the property itself. Overall, the avoidance of conflicts of interest is crucial for maintaining the trustworthiness and reliability of appraisals in the real estate market.
