An appraiser's report must include what to ensure intended users understand the scope of work?

The correct answer is sufficient information. An appraiser's report must include enough detail about the scope of work to ensure that intended users, such as clients or other interested parties, fully understand the analysis and conclusions drawn. This involves clearly outlining the methods used, the extent of the appraisal process, and any assumptions made, allowing users to properly interpret the results and the context in which the appraisal was conducted.

Including sufficient information helps maintain transparency, fosters trust in the appraisal process, and ensures compliance with relevant appraisal standards. Without this level of detail, users may not grasp the rationale behind the appraiser's conclusions, which could lead to misinterpretation or misuse of the appraisal results.
