What does USPAP emphasize regarding the conduct of appraisers?

The emphasis of USPAP (Uniform Standards of Professional Appraisal Practice) on the conduct of appraisers centers around the necessity for independence and impartiality in all assignments. This standard is critical to ensure that appraisals are conducted based on objective analysis and credible data, rather than being influenced by external pressures or biases.

Independence allows appraisers to provide an unbiased estimate of value that reflects the true market conditions, which is essential for the integrity of the appraisal profession. Impartiality ensures that appraisers do not favor one party over another and conduct their work fairly, maintaining the trust of clients, regulators, and the public. The principles outlined in USPAP foster a professional environment where appraisers can fulfill their duties with ethical standards and respect for the law, thus promoting credibility in the appraisal process.

In contrast, the other choices do not align with USPAP's core principles. Emphasizing client relationships may lead to conflicts of interest, which contradicts the need for objectivity. Allowing bias in favor of the client fundamentally undermines the appraisal's integrity and could lead to unethical representations of value. Finally, avoiding documentation of assumptions would hinder transparency and accountability, both of which are critical components of sound appraisal practice as mandated by USPAP.
