No, the deal isn't dead. A low appraisal didn't change what you're allowed to pay for the house. It changed what you can borrow, because the lender sizes your loan on the lower of the purchase price or the appraised value. The appraisal isn't a verdict on the house. It's an input to your loan. Turn the gap into a cash-to-close number and you've got four real options: renegotiate, pay the difference, challenge the value, or walk.
Why does a low appraisal change your loan and not your price?
Because the lender computes loan-to-value against the lower number. Straight from Fannie Mae's Selling Guide, section B2-1.2-01: "Divide the original loan amount by the property value. (The property value is the lower of the sales price or the current appraised value.)" FHA sizes the loan the same way on what HUD Handbook 4000.1 calls "Adjusted Value," and VA does it on the Notice of Value.
Here's the math, as an illustrative example and not an offer or a rate or APR quote of any kind. Contract $500,000, appraisal $485,000, 5% down on a conventional loan. Before the appraisal: loan $475,000 (95% of $500,000), cash toward the price $25,000. After it: loan $460,750 (95% of $485,000), and the price is still $500,000, so cash toward the price is $39,250. The extra is $14,250.
It's not the full $15,000, because your 5% already covered your share of every dollar of price. Extra cash equals the gap times one minus your down-payment percentage. At 20% down, the same $15,000 shortfall costs $12,000. Run your own numbers on the purchase calculator. Math is what I do.
Which option should you look at first?
The internet numbers these one through four. I've been doing this long enough to order them differently.
| Option | Cash-to-close effect | Timing | Who decides |
|---|---|---|---|
| 3. Reconsideration of value (ROV) | Erases the gap if the report has a documented problem; otherwise nothing | Days to weeks; must finish before closing | The appraiser, on the lender's request |
| 1. Seller cuts the price to appraised value | Gap disappears; your loan and down payment hold | Often one conversation | The seller |
| 2. You pay the gap in cash | The lender's share of the gap, sourced, on top of your down payment | Immediate | You, and your lender's asset review |
| 4. Walk away under the appraisal contingency | Zero; earnest money returns if the contingency is still open | Contract deadline | You, inside the contract terms |
Challenge the value first when there's a factual case: it's the only option that erases the gap without anyone paying for it. No factual case? Go to the seller.
Option 1: Can the seller come down to the appraised value?
Often, yes. The CFPB's consumer guidance says it plainly: "You can often use the lower appraised value to negotiate a reduction in the sales price." Fannie Mae research found that a low appraisal raises the probability the buyer renegotiates a better price from 8 percent to 51 percent. That study used September 2011 to August 2012 sales, so read it as how the mechanism behaves, not this month's odds.
Sellers also have more reason to negotiate this fall than they did in 2021 and 2022, for the reasons I cover in is fall 2026 a good time to buy a house.
One thing I see all the time: a seller credit pays closing costs and doesn't fix a value gap, because the loan is still sized on the lower of price or value. If you're splitting the difference, split the price.
Option 2: Should you pay the difference in cash?
Sometimes, and only after you've run the number above. The gap money sits on top of your down payment and gets the same asset verification. Fannie Mae defines a large deposit as "a single deposit that exceeds 50% of the total monthly qualifying income for the loan," and when a large deposit is needed to close a purchase, the lender "must document that those funds are from an acceptable source." Seasoning overlays vary by lender.
If your agent wants appraisal-gap coverage in your offer, that's the same money in advance: you agree to cover up to a stated dollar amount of any shortfall. Set the cap at a number you've verified you can bring on top of your down payment and closing costs. Your agent or attorney drafts the language, and forms differ by state.
It's a bad idea when the cap eats your reserves, or when the appraisal is telling you something true. The CFPB puts it this way: "It is very risky to purchase a home for more than the appraised value." I'd rather see a client walk than close with nothing left.
Option 3: How do you dispute a low appraisal?
Through a reconsideration of value. An ROV is a comps argument, not a complaint. The bank regulators' joint guidance of July 18, 2024 defines it as "a request to reassess the report based upon deficiencies or information that may affect the value conclusion." The process exists so you can raise unsupported, inaccurate, or deficient elements of a report, including possible discriminatory practices, through a documented request.
Under rules FHFA announced on May 1, 2024 and revised effective September 3, 2025, Fannie Mae's Selling Guide requires that "the lender must have policies and procedures in place for a borrower-initiated reconsideration of value," that you receive a disclosure of the process with the appraisal report, and that "only one borrower-initiated ROV is permitted per appraisal." You can't file an ROV after closing. Freddie Mac's Guide section 5604.4 matches. Curious what the lender's review already did? That's in mortgage underwriting explained.
Fannie Mae wants the "identification and description of unsupported, inaccurate, or deficient areas in the appraisal report" plus, in the Guide's words, "Additional data, information, or comparable properties (not to exceed five)," with an explanation of why the new data supports the request. In practice:
- Factual errors: square footage, bed and bath count, lot size, condition rating, upgrades the appraiser didn't see.
- Up to five closed sales the report didn't use, with address, price, date, and living area, and why each one is a better match than what the report used.
- Nothing from an automated valuation. A comp is a closed sale the appraiser can verify. Freddie Mac treats interested-party comp data used "without verification by a disinterested party" as an unacceptable appraisal practice. A Zestimate goes nowhere.
You get one ROV per appraisal, so build it well. This is where knowing the guidelines better than the people applying them pays off: the strongest ROV package I can help you build reads like the appraiser's own standards turned back on the report.
Can you just get a second appraisal?
Mostly no, and this is the option the internet keeps listing anyway. Under Fannie Mae's Appraiser Independence Requirements, the lender or its agent selects and pays the appraiser, and a report from an appraiser "selected, retained, or compensated in any manner by the borrower" won't be accepted. You can't hire your own. Your agent can't. I can't.
The lender can order a second appraisal only when "there are indicators that the initial appraisal was inaccurate, not credible, or in violation of legal and/or professional standards related to nondiscrimination," documented in the file, and even then it must follow "a policy of selecting the most reliable appraisal, rather than the appraisal that states the highest value."
The honest fifth option, conventional only: because I have access to 100+ wholesale lenders, I can sometimes move a conventional file to a different lender that orders its own appraisal. It's never available on FHA or VA, where the value follows the case number or the Notice of Value, and it's only a move when the first report has a documented problem, not because the number was disappointing. The new lender is bound by the same test: the most reliable report wins, not the higher one.
Option 4: Can you walk away and keep your earnest money?
If your appraisal contingency is still open, generally yes. The contingency lets you exit or renegotiate when the appraised value comes in below the price. Deadlines, notice forms, and what happens to earnest money after a missed deadline are contract- and state-specific, so your agent or attorney drafts and interprets your contract. Read the contingency deadline before you do anything else. An ROV that runs past it can cost you the exit.
If you waived the contingency, or it's expired, walking away is a breach question, not a financing question.
What changes if it is an FHA or VA loan?
The value sticks to the file.
| Rule | Conventional (Fannie Mae / Freddie Mac) | FHA | VA |
|---|---|---|---|
| Who starts a value dispute | You, through a borrower-initiated ROV | The underwriter, when the appraiser "did not consider information that was relevant" | You, in writing to the Regional Loan Center after the Notice of Value |
| How long the value lasts | Appraisal within 12 months of the note date; update required past 4 months | 180 days from the effective date; an update extends it to one year | Notice of Value valid for 6 months |
On FHA, HUD added borrower-initiated ROV requirements in Mortgagee Letter 2024-07, then rescinded them in Mortgagee Letter 2025-08 on March 19, 2025, "to restore previous policy." The current Handbook, in the edition issued August 12, 2026, says "the underwriter may request a reconsideration of value when the Appraiser did not consider information that was relevant on the effective date of the appraisal." So the route is the same package, handed to your lender with a request that the underwriter send it. The 180-day validity period keeps that value attached to the case number even if you change lenders. More in FHA loan questions.
VA gives you a warning first. Under its Tidewater procedure, the appraiser has to notify the lender before completing the report "when it appears that the estimated market value will be below the sales price," and "will allow 2-business days" for more sales data. That's your window, before the number is final. After the Notice of Value is issued you can still request reconsideration in writing to the Regional Loan Center. VA staff review within 5 business days, a field review can take up to 20, and an increase comes as an amended notice. More in VA loan questions.
How often do appraisals come in low?
Less often than the panic suggests. Cotality, formerly CoreLogic, reported that among home sales in the closing process in June 2024, 8.6% were appraised below the contract price, down from 10.7% a year earlier. Those are published statistics about the market as of their dates, not your odds on a specific house.
FAQ
What happens to my rate lock while the ROV or renegotiation runs? The clock keeps running. If the lock is going to expire first, ask about an extension early. Terms vary by lender. The mechanics are in rate locks 101.
What if I have no appraisal contingency at all? Then the appraisal isn't an exit, and the gap is yours to negotiate or fund. Talk to your agent or attorney before sending notice of anything. This is exactly why I ask clients to run the gap math before they waive.
