When should a reviewer adopt portions of an appraisal under review?

A reviewer should adopt portions of an appraisal under review when those portions of the report are credible. This means that the data, analysis, and conclusions presented in the appraisal are supported by sound methodologies and reliable information. If a review reveals that certain aspects of the appraisal are based on thorough research, accurate market data, and appropriate application of appraisal principles, then the reviewer can confidently adopt those elements without needing to repeat the entire analysis.

Credibility is essential in appraisal work, as it ensures that the conclusions drawn are valid and can withstand scrutiny. By adopting credible portions of the appraisal, the reviewer strengthens their own findings and provides a more comprehensive evaluation. This process also allows for efficiency, as the reviewer does not need to reconstruct every part of the original appraisal, but instead can use the reliable components as a foundation for their assessment.

The other options present scenarios that might not warrant the adoption of appraisal portions. Incomplete reports typically indicate a lack of sufficient information to make a judgment. Relying solely on independent verification of conclusions can limit the review process to potentially credible elements, neglecting aspects that are valid without extensive re-verification. Lastly, expressing a new opinion of value does not inherently justify adopting parts of the original appraisal, especially if those parts lack credibility
