An extraordinary assumption must be:
Correct Answer
C) Clearly disclosed and its impact on value discussed
USPAP requires that extraordinary assumptions be clearly disclosed in the report and that the appraiser discuss their impact on the assignment results. The appraiser must also explain why the assumption is necessary.
Why This Is the Correct Answer
USPAP Standards Rule 1-4(f) explicitly requires that extraordinary assumptions be clearly and conspicuously disclosed in the report. The appraiser must not only identify the assumption but also analyze and explain how it impacts the assignment results and final value conclusion. Additionally, the appraiser must explain why the extraordinary assumption is necessary for the assignment. This transparency ensures that users of the report understand the conditional nature of the conclusions.
Why the Other Options Are Wrong
Option A: Reasonable and supported by market evidence
While extraordinary assumptions should be reasonable, USPAP does not require them to be supported by market evidence - that would contradict their nature as assumptions about uncertain information. If market evidence existed, an assumption would not be necessary.
Option B: Disclosed in the report but verification is optional
This is incorrect because USPAP requires more than just disclosure - the appraiser must also analyze and discuss the impact on assignment results. Additionally, verification is not optional when it's reasonably possible to obtain the information.
Option D: Avoided whenever possible regardless of assignment conditions
While extraordinary assumptions should be used judiciously, USPAP recognizes they are sometimes necessary for assignment completion. The standard provides specific requirements for their use rather than requiring they be avoided entirely.
DID Method for Extraordinary Assumptions
DID = Disclose clearly, Impact analysis, Discuss necessity. Remember: You DID make an assumption, so you must DID the requirements.
How to use: When you see questions about extraordinary assumptions, think DID - the answer should include clear disclosure, impact analysis, and discussion of necessity, not just one element.
Exam Tip
Look for answers that include both disclosure AND impact analysis - partial compliance answers are typically incorrect on USPAP questions.
Common Mistakes to Avoid
- -Thinking disclosure alone is sufficient without impact analysis
- -Confusing extraordinary assumptions with hypothetical conditions
- -Believing extraordinary assumptions must be supported by market evidence
Concept Deep Dive
Analysis
An extraordinary assumption is a supposition regarding uncertain information used in an assignment that, if found to be false, could alter the appraiser's opinions or conclusions. USPAP Standards Rule 1-4(f) specifically addresses extraordinary assumptions and requires strict disclosure and impact analysis. These assumptions are used when key information is uncertain or unavailable, but the assignment must proceed. The appraiser cannot simply make assumptions without proper disclosure and analysis of how these assumptions affect the final value conclusion.
Background Knowledge
USPAP Standards Rule 1-4(f) governs the use of extraordinary assumptions in appraisal assignments. Appraisers must understand the difference between extraordinary assumptions (uncertain information) and hypothetical conditions (contrary-to-fact scenarios).
Real-World Application
When appraising a property with potential environmental contamination but no recent environmental report, an appraiser might use an extraordinary assumption that the property is not contaminated, but must clearly disclose this assumption and explain how a different environmental condition would affect the value conclusion.
