An extraordinary assumption helps appraisers handle uncertainties during property evaluations when specific information is missing or inaccessible. According to the Uniform Standards of Professional Appraisal Practice (USPAP), an extraordinary assumption is “an assumption which, if found to be false, could alter the resulting opinion or conclusion.” With this tool, appraisers can proceed with temporary conclusions about unknown elements, fully aware that these assumptions might impact final valuations.
When Are Extraordinary Assumptions Used?
Appraisers often use extraordinary assumptions in scenarios with limited property access, such as in exterior-only or drive-by appraisals. In these cases, only the property’s exterior is visible. Appraisers rely on alternative data sources to gather information on areas they cannot access. These sources include Multiple Listing Service (MLS) entries, property tax records, and homeowner-provided details. Since this data can sometimes be inaccurate or incomplete, appraisers use extraordinary assumptions to bridge information gaps and create a complete appraisal report.
For example, during a mortgage appraisal, an appraiser unable to access a finished basement might assume it reflects the rest of the property’s condition. However, if this assumption proves incorrect, the property’s appraised value may change significantly.
Common Uses of Extraordinary Assumptions
Extraordinary assumptions apply in cases with limited access to parts of a property. Here are common scenarios where appraisers use extraordinary assumptions:
- Exterior-Only Appraisals: In drive-by appraisals, appraisers can only evaluate the exterior. They rely on external sources to infer the interior condition, assuming it matches the exterior.
- Inaccessible Areas: Appraisers may assume that locked areas, like sheds or garages, are in similar condition to the rest of the property.
- Utilities and Systems: In winterized or vacant homes with disconnected utilities, appraisers might assume systems are operational even if they can’t test them.
- Construction Areas: For properties under construction, appraisers assume unfinished areas will meet code requirements and standards.
- Historical Properties: Appraisers might assume renovations on historical homes maintain the original property’s integrity unless stated otherwise.
Limits of Extraordinary Assumptions
While helpful, extraordinary assumptions have limitations. Some property issues require specific knowledge and cannot be covered by assumptions. For instance, if a homeowner reports hail damage on the roof, the appraiser cannot assume it is undamaged. Extraordinary assumptions also differ from hypothetical conditions, which involve knowingly false scenarios, such as appraising a proposed but unbuilt property.
Reliance on third-party information is another limitation. If MLS data or tax records are outdated or incorrect, they may reduce the appraisal’s accuracy. Appraisers should verify data reliability before making any extraordinary assumptions.
Case Study: Applying Extraordinary Assumptions
In a recent drive-by appraisal for a pre-listing appraisal, the appraiser could not access the detached garage due to a lock issue. Based on the property’s overall condition, the appraiser assumed the garage was in similar good condition as the main house. This assumption was fully disclosed in the appraisal report, noting that any change to this assumption could affect the valuation.
Another example involves a winterized property with disconnected utilities. The appraiser assumes that all systems, like heating and plumbing, are functional despite being off. If later found inaccurate, this assumption could lead to a reassessment of the property’s value.
Enhancing Transparency with Extraordinary Assumptions
Transparent use of extraordinary assumptions helps appraisers maintain trust and integrity. Clear documentation ensures all stakeholders understand how these assumptions might impact the final valuation. This transparency is crucial in real estate transactions, where appraisals influence financing and purchasing decisions.
Moreover, extraordinary assumptions enable appraisers to provide timely evaluations despite incomplete information. In fast-moving real estate markets, delays can impact transaction timelines and financing. Clear documentation of assumptions also protects appraisers from legal issues by making all parties aware of the provisional nature of the appraisal.
Best Practices for Using Extraordinary Assumptions
Appraisers can use extraordinary assumptions more effectively by following these best practices:
- Detailed Documentation: Clearly document each extraordinary assumption in the report, explaining the reasoning behind it.
- Impact Disclosure: Inform clients about potential risks tied to these assumptions, including possible effects on valuation if found incorrect.
- Verification Efforts: Verify information from available data sources before making assumptions, increasing reliability.
- Periodic Training: Stay updated on industry standards to ensure accuracy and compliance in using extraordinary assumptions.
- Client Communication: Maintain open communication with clients to clarify the importance and implications of extraordinary assumptions.
- Use of Technology: Utilize appraisal tools that help verify data, reducing the need for assumptions.
Conclusion
Extraordinary assumptions enable appraisers to provide timely and reliable evaluations in uncertain conditions. However, appraisers must use them transparently and responsibly to preserve the integrity of their work. Properly applied, extraordinary assumptions help appraisers deliver accurate valuations that support informed decisions for buyers, sellers, and lenders.

Frequently Asked Questions
What is an extraordinary assumption in property appraisal?
An extraordinary assumption is an assumption made by an appraiser about certain property aspects that are unknown or inaccessible during the appraisal. If this assumption is later found to be incorrect, it could impact the appraised value.
How does an extraordinary assumption differ from a hypothetical condition?
An extraordinary assumption assumes certain conditions are true but unknown, while a hypothetical condition involves known false information. For instance, assuming a locked room is in good condition is an extraordinary assumption, while appraising a building as if it were completed is a hypothetical condition.
When are extraordinary assumptions most commonly used?
Extraordinary assumptions are often used in exterior-only or drive-by appraisals, situations where certain areas are inaccessible, or for properties with disconnected utilities. They allow appraisers to make provisional judgments where information is lacking.
Are extraordinary assumptions disclosed to clients?
Yes, appraisers are required to disclose any extraordinary assumptions used in the appraisal report. This transparency ensures clients are aware of any assumptions made and understand how they may affect the final valuation.
Can an extraordinary assumption impact my loan approval?
Yes, if the extraordinary assumption proves to be inaccurate, it could affect the property’s appraised value, potentially impacting loan approval or financing terms. It is essential for buyers and lenders to understand these assumptions during the appraisal process.
Q & A Section
Question: How do appraisers handle uncertainty in a drive-by appraisal?
Answer: In a drive-by appraisal, appraisers face limited access to a property’s interior, relying on observable exterior details and external sources like MLS data or public records. To address this uncertainty, they often use extraordinary assumptions, where they assume unknown aspects, such as interior condition, are consistent with available information. This assumption is clearly disclosed in the report to ensure transparency, and clients are informed of the potential impact on the valuation if the assumption is found inaccurate.
