The use of terms that reflect a scale such as "good" or "average" in an appraisal report should include what?

The use of terms like "good" or "average" in an appraisal report requires an explanation that provides context. This is crucial because such qualitative descriptors can vary widely in interpretation without proper grounding. By providing context, the appraiser clarifies what "good" or "average" means in the specific scenario at hand. This may include details regarding market conditions, property type, or specific attributes that led to that categorization. This contextual explanation helps to eliminate ambiguity and ensures that stakeholders can understand the basis of the appraisal as well as the reasoning behind certain ratings.

The other choices, while they may seem relevant, do not adequately address the importance of clarity within the report. A disclaimer could be useful in different contexts but does not provide the necessary context for understanding specific terminology. National standards might offer guidelines, but they are not tailored to an individual property assessment's unique characteristics. Comparisons to industry-wide standards, while informative, can still leave room for misinterpretation without a personalized explanation. Thus, providing context enhances transparency and supports the credibility of the appraisal.
