An extraordinary assumption is defined as an assumption that:
Correct Answer
D) If false, could alter the appraiser's conclusions
Why this is correct: USPAP defines an extraordinary assumption as an assumption that, if found to be false, could materially alter the appraiser's opinions or conclusions. It is specific to an assignment and carries significant risk. The appraiser must disclose it and ensure it is reasonable. Why the other choices are wrong: "Is commonly made in similar assignments too" describes an ordinary assumption, which is generally accepted and unlikely to alter conclusions if false. "Requires additional research in order to verify" describes a condition that might lead to an assumption but isn't the definition. "Is directly related to a specific assignment" is true but not the distinguishing factor; ordinary assumptions are also assignment-specific. Exam tip: Extraordinary assumptions are "what ifs" that, if wrong, change the answer. They require clear disclosure.
Why This Is the Correct Answer
Option B correctly captures the essence of an extraordinary assumption as defined by USPAP. The defining characteristic is that if the assumption proves false, it would materially alter the appraiser's opinions, conclusions, or value estimate. This potential for material impact is what makes the assumption 'extraordinary' rather than ordinary. The definition emphasizes the consequential nature of the assumption - it's not just any assumption, but one with significant potential to change the entire appraisal outcome.
Why the Other Options Are Wrong
The FALSE-ALTER Rule
Remember 'FALSE-ALTER': If the assumption proves FALSE, it would ALTER the appraiser's conclusions. This captures the essence that extraordinary assumptions are those that, when proven incorrect, would materially change the appraisal outcome.
How to use: When you see questions about extraordinary assumptions, immediately think 'FALSE-ALTER' - look for the answer choice that emphasizes the potential for material change in conclusions if the assumption proves incorrect.
Exam Tip
Focus on the word 'extraordinary' - it implies something beyond ordinary that could have significant consequences. Look for answer choices that emphasize material impact or potential to alter conclusions.
Common Mistakes to Avoid
- -Confusing extraordinary assumptions with ordinary assumptions that are commonly accepted
- -Thinking that assignment-specific nature alone makes an assumption extraordinary
- -Believing that research requirements define extraordinary assumptions rather than their potential impact
Concept Deep Dive
Analysis
Extraordinary assumptions are critical concepts in appraisal practice that represent uncertain conditions that could significantly impact the valuation if proven incorrect. Unlike ordinary assumptions that are commonly accepted and rarely questioned, extraordinary assumptions involve material uncertainty that requires specific disclosure and could fundamentally change the appraisal outcome. The key distinguishing factor is the potential materiality of the assumption - if the assumption turns out to be false, it would alter the appraiser's conclusions. USPAP requires appraisers to clearly identify and disclose extraordinary assumptions because they represent conditions that are uncertain, could reasonably be expected to exist, and would affect the assignment results if found to be false.
Background Knowledge
USPAP (Uniform Standards of Professional Appraisal Practice) distinguishes between ordinary and extraordinary assumptions based on their potential impact on appraisal conclusions. Extraordinary assumptions must be clearly disclosed in appraisal reports because they represent material uncertainties that could affect the reliability of the valuation.
Real-World Application
An appraiser valuing a property assumes that a planned highway extension will be completed as scheduled, significantly affecting property access and value. If this highway project is cancelled or delayed, the assumption proves false and would materially alter the property's value conclusion, making this an extraordinary assumption requiring disclosure.
