What is the first action an appraiser must take if they lack the necessary competency for an appraisal review assignment?

Informing the client of the lack of competency is crucial as it maintains transparency and upholds professional ethics. An appraiser must always act in the best interest of the client and the public by being honest about their qualifications and capabilities. Acknowledging limitations allows the client to make informed decisions about the assignment, potentially choosing to seek a more qualified appraiser.

This action also aligns with the ethical obligations set by appraisal organizations, which emphasize integrity and competency in professional practice. Being upfront about deficiencies in competency is not just a best practice; it is essential for maintaining trust and credibility in the appraiser-client relationship. This approach safeguards the appraiser’s reputation and helps ensure that clients receive the quality of service they expect.

The other options would lead to potential ethical violations or compromised appraisal quality. For instance, declining the offer immediately might not provide any value to the client or context regarding the appraiser's limitations. Seeking assistance is certainly a viable path, but it should follow the initial declaration of incompetency to allow the client to decide if they want to proceed or not. Finally, agreeing to perform the assignment without adequate competency would not only jeopardize the appraisal's accuracy but also contravene ethical standards, potentially harming the client and the public interest.
