What term describes an assumption made by an appraiser when evidence suggests that a fact is not certain?

The term that best describes an assumption made by an appraiser when evidence suggests that a fact is not certain is "hypothetical condition." This term refers to a situation where an appraiser makes an assumption that is contrary to known facts, often to analyze how an asset might perform under certain hypothetical scenarios. When an appraiser relies on a hypothetical condition, they are acknowledging that the assumption may not be true and that the conclusions drawn from it are based on these unsupported premises.

The other terms available do not fit this definition as accurately. While "extraordinary condition" might refer to unusual circumstances affecting value, it does not specifically pertain to assumptions made based on uncertainty. Similarly, "implied condition" suggests a condition that is assumed to exist but is not overtly stated, and "assumed condition" may refer more generally to any condition that an appraiser takes for granted, without the specific context of uncertainty based on evidence. Therefore, "hypothetical condition" is the most accurate choice in this context.
