Who is responsible for ensuring that all necessary information is included in an appraisal report?

The appraiser holds the primary responsibility for ensuring that all necessary information is included in an appraisal report. This responsibility stems from the appraiser's role as the professional who conducts the appraisal, evaluates the relevant data, and formulates an opinion of value based on that data.

An appraisal report must adhere to specific guidelines and standards, such as those set by the Uniform Standards of Professional Appraisal Practice (USPAP), which mandate comprehensive documentation and analysis to support the appraiser's conclusions. The appraiser must ensure that all pertinent information, including property characteristics, comparable sales data, and market trends, is accurately reflected and clearly articulated in the report.

While the supervising appraiser plays a guiding role and may assist in reviewing the report, the ultimate accountability lies with the appraiser. The appraisal assistant may help gather data and prepare materials, but they do not bear the same level of responsibility for the final report. Similarly, the client has an interest in the report's quality but is not involved in its completion or the details of the appraisal methodology. Thus, the appraiser's comprehensive responsibilities make them the correct choice for this question.
