Homes appraise for less than the asking price in a small minority of deals: about 8% of residential contracts run into appraisal-related delays, according to the March 2026 Realtors Confidence Index, and that single-digit rate has held steady for years.1National Association of REALTORS®. REALTORS Confidence Index Report In a 2023 survey of real estate professionals, 64% said appraisals met or exceeded the contract price most of the time or always, and only 12% said low appraisals happened frequently in their transactions.2National Association of REALTORS®. 2023 Appraisal Survey So the odds are on your side. The question worth planning for is what happens in the roughly one deal in twelve where the number falls short.
Why the Rate Moves With the Market
The low-appraisal rate drifts up during periods of rapid price appreciation and drifts down in calmer markets. The pattern holds across conventional, FHA, and VA loans.
The mechanism is a timing mismatch that agents call appraisal lag. Appraisers build their opinion of value from comparable sales, meaning recently closed transactions for similar nearby homes, and Fannie Mae requires them to report a 12-month sales history for each comparable they choose.3Fannie Mae. Sales Comparison Approach Section of the Appraisal Report When bidding wars push prices up over a few weeks, the closed sales the appraiser must rely on are already stale. Federal rules require valuations to conform to the Uniform Standards of Professional Appraisal Practice and rest on verifiable market data, not on the appraiser’s read of buyer enthusiasm.4eCFR. 12 CFR Part 323 – Appraisals Low inventory makes the lag worse because there are fewer comparables to work with.
One common misconception: Fannie Mae’s guide does not set a hard one-mile limit or require three comps. It requires the “most comparable” closed sales, contracts, and listings.3Fannie Mae. Sales Comparison Approach Section of the Appraisal Report Appraisers prefer nearby sales, but in rural areas or unusual neighborhoods they can reach further.
When the House Itself Is the Reason
Market conditions aside, the property can drive the number down. The appraiser walks the home and evaluates the roof, HVAC, electrical panel, plumbing, and structural components. Visible deferred maintenance and systems near the end of their useful life pull values below what sellers expect.
Unusual upgrades create a different problem. A $60,000 kitchen in a neighborhood where no comparable home has anything close will not translate into $60,000 in appraised value, because there is no local data to support that jump. The same goes for oversized additions, unusual floor plans, home theaters, and indoor pools. Improvements pay back most reliably when they match what neighboring homes already have.
If you’re the seller or the buyer arranging access, hand the appraiser documentation before the visit: permits, inspection reports, and receipts for major work like a roof replacement or foundation repair. Without paperwork, the appraiser has to estimate conservatively.
Your Options When the Number Comes In Low
A low appraisal doesn’t kill a deal automatically, but it forces a choice. The lender caps the loan at the appraised value, not the contract price. Agree to buy at $400,000, get an appraisal of $380,000, and $20,000 becomes someone’s problem.
You generally have four ways out:
- Cover the gap in cash. You bring the difference to closing on top of your planned down payment and closing costs. The contract stays intact, but the money has to be liquid.
- Negotiate a price reduction. The seller drops the price to match or approach the appraised value. Sellers agree more readily when the market has cooled or the listing has been sitting.
- Split the difference. Buyer and seller each absorb part of the gap. On a $20,000 shortfall, a common landing spot is $10,000 off the price and $10,000 in extra cash from the buyer.
- Walk away under the appraisal contingency. If your contract includes one, you can terminate and get your earnest money back. Without that contingency, walking away puts your deposit at risk.
Any price change has to be documented in a signed amendment to the purchase contract and sent to the lender’s underwriting team so the loan file reflects the new terms.
How the Loan-to-Value Math Shifts
Conventional mortgages can go as high as 97% loan-to-value, but anything above 80% triggers private mortgage insurance.5Fannie Mae. Mortgage Insurance Coverage Requirements A low appraisal recalculates LTV against the lower number. Suppose you planned to put 10% down on $400,000, borrowing $360,000. That’s 90% LTV against the contract price. If the appraisal lands at $380,000, the same $360,000 loan is now roughly 94.7% LTV. You may move into a higher PMI bracket, and your monthly payment can change even if the loan amount doesn’t.
Appraisal Gap Coverage Clauses
In competitive markets, some buyers include an appraisal gap coverage clause in their offer: a written commitment to pay some or all of any shortfall, usually up to a stated dollar amount or percentage. Sellers like these clauses because the risk moves entirely to the buyer. Commit to covering the gap on a $500,000 purchase and see the appraisal land at $425,000, and you owe $75,000 in cash above your down payment. That money bridges the gap between what the lender will finance and what the seller expects to receive; it does not build equity for LTV purposes.
If you’re weighing this kind of clause, set a firm dollar cap you can actually afford. An open-ended guarantee is the quickest way to overextend in a bidding war.
Challenging a Low Appraisal
You cannot simply order a second appraisal because you dislike the first. The formal process is called a Reconsideration of Value, and it runs through your lender rather than directly to the appraiser. Fannie Mae and FHA both limit borrowers to one ROV request per appraisal.6Fannie Mae. Reconsideration of Value (ROV)
An ROV is not a general complaint. The Consumer Financial Protection Bureau identifies three valid grounds: factual errors in the report, inadequate or outdated comparable sales when better ones exist, and evidence of prohibited bias.7Consumer Financial Protection Bureau. Mortgage Borrowers Can Challenge Inaccurate Appraisals Through the Reconsideration of Value Process The strongest requests come with alternative comparable sales the appraiser may have missed. FHA borrowers can submit up to five alternative comparables for the appraiser to consider, and lenders cannot charge FHA borrowers any fee for the ROV process.8U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook
Factual errors also carry weight: wrong square footage, a missing bathroom, an incorrectly noted condition issue. Minor errors that don’t affect value must still be corrected. Material errors require the appraiser to reassess.6Fannie Mae. Reconsideration of Value (ROV) A real estate agent who knows the neighborhood and can pull genuinely comparable recent sales is the single most useful ally here. Generalized arguments that “the market is hot” won’t move the number.
FHA and VA Rules Change the Picture
FHA Loans
FHA calculates the maximum mortgage using what HUD calls the Adjusted Value, the lesser of the purchase price or the appraised value. A low appraisal caps the FHA loan just as it caps a conventional one. The wrinkle is timing: an FHA appraisal remains valid for 180 days from the effective date and can be extended to one year with an update.8U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook During that window the appraisal is tied to the property’s FHA case number. If your deal falls through and another FHA buyer comes along inside those 180 days, the lender may need to use the same appraisal rather than order a fresh one, which is a problem if the original number was low.
VA Loans
Veterans have a stronger safeguard called the VA Escape Clause, which by law must appear in every VA home loan purchase contract. If the VA’s reasonable value determination comes in below the contract price, the veteran can negotiate a lower price with the seller, cover the difference in cash with the loan capped at the reasonable value, or walk away without forfeiting the earnest money deposit. The clause is mandatory. Even if a veteran signs loan paperwork before the VA’s Notice of Value arrives, the escape clause still lets them back out penalty-free if the value falls short.9U.S. Department of Veterans Affairs. VA Escape Clause That is a stronger position than a standard appraisal contingency, which only helps a buyer who remembered to write it into the contract.
When There Is No Appraisal at All
Not every purchase requires a traditional appraisal. Fannie Mae’s Value Acceptance program allows certain low-risk loans to close without one. When a loan runs through Fannie Mae’s automated underwriting system and qualifies, the lender can accept its own value estimate instead of a full appraisal report.10Fannie Mae. Value Acceptance
Eligibility is narrow. Properties valued at $1 million or more, multi-unit homes, co-ops, manufactured housing, new construction, and manually underwritten loans are excluded.10Fannie Mae. Value Acceptance On a purchase, the estimated value submitted to the underwriting system must match the contract price. A value acceptance offer removes the possibility of a low appraisal because there is no appraisal, and it also removes the independent check on whether you’re overpaying. If your lender mentions waiving the appraisal on a qualifying loan, weigh what the safety net was worth to you before agreeing.
Set against the roughly 8% chance of a delay, the practical takeaway is this: budget for a possible gap before you make an offer in a hot market, know which of the four options you would actually use, and confirm the appraisal contingency (or, for VA buyers, the escape clause) is in the contract you sign.
