How should appraisers handle data limitations in their reports?

• A. Describe data limitations but not their impact.
• B. Hide data limitations to present a more favorable conclusion.
• C. Clearly describe data limitations and their impact on conclusions to maintain transparency.
• D. Only mention data limitations if the client requests.

Answer: (C)

The key idea is transparency: when data is incomplete or limited, an appraiser must clearly describe what is missing and exactly how that limits the analysis and affects the conclusions. That includes identifying the specific data gaps, the reasons for the limitations, and the impact on reliability, certainty, or the range of values the appraisal could reasonably support. By laying out these details, the report shows users how confident they should be in the conclusion and what risks or alternative considerations exist. This approach aligns with professional standards that require disclosing limiting conditions to maintain credibility and avoid misleading conclusions. Hiding limitations, or raising them only if asked, would obscure the true reliability of the appraisal, while addressing the limitations openly often leads to appropriate adjustments in scope, additional data gathering, or reporting of a valuation range to reflect uncertainty.
