The quick read: It depends on the assumption and the lender's review. An extraordinary appraisal assumption identifies uncertain information that could change the value conclusion if it proves false; it does not establish that the information is verified. Before relying on closing proceeds, identify the uncertainty, provide supporting evidence and obtain the lender's accepted valuation and funding conditions.
What does an extraordinary assumption tell the borrower?
An extraordinary assumption tells the borrower that the appraiser treated specified uncertain information as true for the assignment, and that a different fact could change the conclusion. Read the actual assumption beside the value and effective date. The report's dollar amount should not be separated from the information on which the appraiser relied.
The Interagency Appraisal and Evaluation Guidelines, Appendix D, describe an extraordinary assumption as assignment-related information that could alter the value opinion if false. The guidelines separately distinguish a hypothetical condition concerning a known contrary fact. These are definitions reproduced in official supervisory guidance; this article does not claim access to paid professional standards. Federal Reserve's official guidelines.
For a borrower, the difference is practical. Unverified lease information and a scenario deliberately assuming a completed improvement do not create the same evidence problem. Identify which type the report actually uses rather than calling every limitation an extraordinary assumption. Ask the lender's valuation reviewer how that assumption affects the decision being made.
The uncertainty may concern physical condition, legal rights or economic information. It does not automatically mean the report is unusable. It does mean the financing team needs a clear account of what remains uncertain before the owner relies on a proceeds calculation or waives a contractual financing condition.
Which evidence can resolve an assumption about rental information?
Evidence can resolve an assumption about rental information when it establishes the actual lease terms or collections the report treated as uncertain and is submitted through the lender's authorized review process. Match each document to the stated uncertainty. A new summary repeating the original rent roll does not independently establish that the underlying information is correct.
A 2017 SEC-filed NorthStar Real Estate Income II appraisal report illustrates the issue. Its extraordinary-assumptions section relies on supplied rent-roll information accurately reflecting lease documents, and on operating information accurately reflecting the properties. The report was prepared for the disclosed financial-reporting purpose, not as a loan appraisal commissioned for this borrower. It is a specimen of disclosed data assumptions. SEC-filed report.
If a stated rent is uncertain, provide the executed lease and amendments, identifying commencement, concessions and other terms relevant to that line. If the uncertainty concerns receipts, reconcile the applicable ledger and evidence of collections. Neither document necessarily answers the other's question: a valid rent obligation differs from proof that the tenant paid it.
Identify the current version and explain any correction to an earlier submission. For example, an amended lease could reduce rent while the property manager's summary still carries the original amount. State the difference and its effective period rather than presenting an unexplained replacement total. Preserve the source documents so the lender and appraiser can evaluate their significance.
How can corrected information change the cash needed to close?
Corrected information can change closing cash when the lender's accepted valuation and resulting proceeds differ from the owner's initial financing model, even if the transaction price stays unchanged. Test the exposure with clearly labeled assumptions. The borrower should not calculate an automatic appraisal adjustment or treat a sensitivity model as the appraiser's revised conclusion.
Table 1: Hypothetical rent correction and closing-cash sensitivity
| Fictional input or calculation | Original assumed data | Corrected-data sensitivity |
|---|---|---|
| Fictional input or calculation Annual property NOI used in this illustration | Original assumed data $500,000 | Corrected-data sensitivity $480,000 |
| Fictional input or calculation Assumed capitalization rate held constant | Original assumed data 8% | Corrected-data sensitivity 8% |
| Fictional input or calculation Illustrative value: NOI divided by assumed rate | Original assumed data $6,250,000 | Corrected-data sensitivity $6,000,000 |
| Fictional input or calculation Assumed loan at 65% of illustrative value | Original assumed data $4,062,500 | Corrected-data sensitivity $3,900,000 |
| Fictional input or calculation Purchase and closing uses | Original assumed data $4,300,000 | Corrected-data sensitivity $4,300,000 |
| Fictional input or calculation Owner cash needed for these uses | Original assumed data $237,500 | Corrected-data sensitivity $400,000 |
Every input is hypothetical. Suppose correcting a lease line reduces annual income by $20,000 with other income and expenses held constant. The simplified model produces a $250,000 value difference and a $162,500 proceeds difference. The owner cash rises by the same $162,500: $400,000 minus $237,500.
That result measures exposure in this constructed scenario. An appraiser would need to evaluate the actual lease, other valuation evidence and the effect of the correction; the capitalization rate need not remain unchanged. Debt-service coverage, cost, reserves and lender restrictions can also make the final loan smaller than the illustrated value-based amount.
Run the cash schedule using the amount actually accepted by the lender before depending on the higher figure. Identify whether an additional contribution is available, which transaction terms can be renegotiated and what contractual deadline governs that choice. A value correction is not automatically a right to extend the purchase contract or change the purchase price.
What outcomes should the lender's valuation review distinguish?
The lender's valuation review should distinguish a supported assumption accepted for the actual credit decision from an unresolved deficiency or a different valuation scenario needed for funding. Ask for the outcome and any conditions in writing. A report being received by the lender does not establish that its value has been accepted for the proposed advance.
The interagency guidelines describe resolving valuation inaccuracies or weaknesses through the review process and documenting that resolution. For covered institutions, an appraisal inconsistent with the regulations that cannot be corrected requires a compliant appraisal or evaluation before the credit decision. That is a supervisory requirement, not a guarantee that a borrower request will be approved.
Table 2: Borrower actions for different review outcomes
| Report or review status | Question to resolve | Cash-plan treatment until confirmed |
|---|---|---|
| Report or review status Assumption supported by documents | Question to resolve Has the reviewer accepted the evidence for this assignment? | Cash-plan treatment until confirmed Use the lender-confirmed proceeds, not the owner's preferred estimate |
| Report or review status Evidence changes a material fact | Question to resolve Does the appraisal need clarification or revision? | Cash-plan treatment until confirmed Maintain a sensitivity case and identify cash exposure |
| Report or review status Critical information remains unknown | Question to resolve Can the lender decide on this basis, or is more evidence needed? | Cash-plan treatment until confirmed Keep the related funding condition visibly unresolved |
| Report or review status Report values a different condition or date | Question to resolve Is a current-condition value also required? | Cash-plan treatment until confirmed Separate current closing funds from future conditional proceeds |
The table describes questions, not a shortcut around the institution's review. Submit facts through the authorized contact. Do not ask the appraiser to remove a qualification solely because the loan needs a larger number. Resolving uncertainty and influencing a predetermined valuation are different actions.
How does an assumption differ from a future completion condition?
An assumption differs from a future completion condition because the report's uncertain facts, its valuation scenario and the lender's funding milestones are separate items that must be read together. Identify each before planning the closing. A value for a completed project does not establish that unfinished work currently satisfies a requirement for an advance.
The OCC Commercial Real Estate Lending handbook explains that construction collateral analysis includes current-condition value and may involve prospective completion or stabilization values. Its bank review framework also addresses appraisal information and assumptions. These are supervisory concepts, not authorization to substitute a future value for whatever collateral basis this lender requires. OCC handbook.
Make a short schedule showing the report's effective date, condition valued and assumption. Add the lender's evidence requirements separately. If an inspection, document or work completion is required before disbursement, record who supplies it and when. An appraisal estimating the future project's value is not itself the completion certificate.
The same discipline applies to an existing property with a proposed change in use. A favorable scenario based on a future approval should remain separated from evidence that the approval has actually occurred. Let the lender's reviewer and the relevant advisers identify the needed confirmation rather than treating an appraisal narrative as permission to begin work or close on different terms.
How should the valuation issue be presented for borrower placement?
Present an appraisal-assumption issue for borrower placement with the relevant report language, the supporting documents and the lender's stated review status rather than only the highest value printed in the report. Include the closing-cash sensitivity and the actual transaction deadlines. Distinguish confirmed evidence from the items still needed for the credit or funding decision.

The bottom line
An extraordinary assumption is a disclosed dependency in the value opinion, not proof that the underlying fact has been verified or that the loan can close. Match the uncertainty to evidence, obtain the lender's review outcome and use confirmed proceeds in the cash plan. If the fact changes, revisit both the valuation and the owner's funding requirement.
