How should a reviewer approach a methodology used in an appraisal that they are not familiar with?

When a reviewer encounters a methodology used in an appraisal that is unfamiliar, asking the appraiser to explain the new methodology is the most appropriate approach. This option promotes open communication and understanding. The reviewer can gather insights into how the methodology was applied, the reasoning behind its use, and its relevance to the specific appraisal. This inquiry allows the reviewer to assess whether the methodology is sound and applicable to the appraisal context.

By fostering dialogue, the reviewer not only supports the appraiser but also enhances their own comprehension of different approaches in appraisal practice. This collaborative exchange can lead to a better evaluation of the report and ultimately contribute to the overall quality of the appraisal process. It also acknowledges that there are various acceptable methods in the field, and understanding these can enrich the reviewer’s expertise.
