If the appraisal is lower than the offer, your lender will only finance a percentage of the appraised value, not the contract price, so a cash gap opens up between what you owe the seller and what the bank will lend. On a $500,000 deal that appraises at $480,000, the property is $480,000 collateral in the lender’s eyes no matter what your contract says. That $20,000 difference can stall the closing, force a renegotiation, or end the deal, depending on what your purchase agreement allows and how much room each side has to move.
How the Shortfall Shrinks Your Loan
Lenders size a mortgage using a loan-to-value ratio, and they apply that ratio to the lower of the purchase price or the appraised value. When appraisal meets price, you never notice the rule. When it falls short, the loan drops with it.
Run the math on the $500,000 example. With 20 percent down at full value, the lender approves $400,000 and you bring $100,000 to closing. If the appraisal comes back at $480,000, the loan is capped at 80 percent of $480,000, or $384,000. The seller still expects $500,000, so you now need $116,000 in cash instead of $100,000. That is $16,000 more than you budgeted, and the lender will not issue final approval until the gap is closed one way or another.
Read the appraisal report closely when it arrives. The comparable sales the appraiser chose, the adjustments they made, and any condition issues they flagged are the foundation for everything you do next, whether that is negotiating, challenging the number, or walking.
Your Options as the Buyer
What you can do depends almost entirely on one clause in the purchase agreement: the appraisal contingency. With it, you have leverage. Without it, your choices narrow quickly.
Pay the Difference in Cash
The most direct path is covering the gap yourself. In the example, you bring $116,000 instead of $100,000, which effectively increases your down payment to offset the smaller loan. This only makes sense if you have the reserves and still believe the property is worth the contract price. Most buyers don’t have an extra $16,000 sitting around, which is why straight cash coverage is less common than renegotiation.
Ask the Seller to Lower the Price
The most common move is asking for a price reduction to match or approach the appraised value. On a $20,000 shortfall, you might request the full $20,000 or propose a split where the seller drops $10,000 and you add $8,000 in cash. How this lands depends on the market. When homes sit for weeks, sellers usually accommodate. In a competitive market with backup offers waiting, the seller may not move at all.
Walk Away Under the Appraisal Contingency
If your contract has an appraisal contingency and the value came in low, you can terminate the deal and recover your earnest money. Timing is the catch. Most contracts give you a specific window, often only a few days after receiving the appraisal, to invoke the contingency in writing. Miss it and you may lose the right to exit cleanly. This is the last-resort option, but it keeps you out of a deal the lender will not fully back.
What Happens Without an Appraisal Contingency
In competitive markets, buyers sometimes waive the appraisal contingency to make an offer more attractive. That choice carries real risk. Without the contingency, you have no contractual right to back out over a low appraisal, and if you cannot close, your earnest money is on the line. In hot markets that deposit can run into tens of thousands of dollars.
If you waived the contingency and the appraisal comes in low, you generally have three choices: pay the full gap in cash, convince the seller to renegotiate voluntarily (they have no obligation to), or walk away and lose your deposit. Some buyers try to use another contingency, such as inspection, to exit. Sellers and their attorneys tend to see that coming.
Appraisal Gap Guarantees
An appraisal gap guarantee sits between waiving the contingency and keeping full protection. It’s a clause in the purchase agreement where you commit to covering a set dollar amount of any shortfall out of pocket. You might guarantee up to $15,000 above the appraised value, for instance. If the gap exceeds that number, you can still invoke the contingency and walk. If it falls within your guarantee, you’re on the hook. The clause lets you compete without unlimited exposure, but the guarantee should reflect what you can actually bring to closing.
How the Seller Usually Responds
The seller’s answer generally tracks their leverage. A seller sitting on multiple offers has little reason to drop the price. A seller who spent weeks on market and finally landed a buyer has every reason to make it work.
Some sellers agree to reduce the price to the appraised value. It’s the fastest route to closing, and sellers often accept because relisting signals a problem to new buyers. A home that falls out of contract attracts scrutiny, and the next buyer’s lender will likely order an appraisal that lands in the same neighborhood.
Others hold firm and insist the buyer either covers the gap or terminates. It’s a gamble. If the buyer walks, the seller relists with a low appraisal already on the record. Any subsequent FHA buyer will encounter that same appraisal for 180 days, since FHA appraisals stay valid for that period and attach to the property, not the borrower.1U.S. Department of Housing and Urban Development. FHA Implements Revised Appraisal Validity Period Guidance Conventional buyers may see similar numbers if comparable sales haven’t changed.
The middle path is a split. On a $20,000 shortfall, the seller drops $10,000 and the buyer covers the other $10,000 with additional cash. Both sides absorb some pain, and the deal closes.
Challenging the Appraisal
Before accepting the number or renegotiating around it, either side can push back through a Reconsideration of Value request. It’s a formal process, and it needs real evidence to work.
Filing a Reconsideration of Value
The request goes to the lender, who is responsible for confirming it meets their investor’s requirements before forwarding it to the original appraiser for review.2Fannie Mae. Reconsideration of Value (ROV) Since 2024, borrowers have a recognized right to initiate their own ROV on loans backed by Fannie Mae, Freddie Mac, or FHA.3U.S. Department of Housing and Urban Development. Mortgagee Letter 2024-07 – Appraisal Review and Reconsideration of Value Updates You get one request per appraisal report.
The strongest ROV submissions fall into two categories. The first is factual errors: wrong square footage, incorrect bedroom count, a missed bathroom, an inaccurate lot size. Those are hard for the appraiser to dismiss. The second is comparable sales the appraiser overlooked. The comps have to be genuinely stronger: more recent, closer, or more similar in size and features. Listings and pending sales won’t do it. You need closed transactions.
Be realistic. Appraisers rarely reverse themselves without compelling new data, and they must update the report to explain any change or explain why the submitted information did not move the number. An ROV is a targeted correction, not a do-over.
Ordering a Second Appraisal
If the ROV fails, you can pay for a second independent appraisal. It can be useful leverage in negotiation with the seller or if you’re considering switching lenders. A new lender is not obligated to accept someone else’s appraisal and may order its own anyway. A standard single-family appraisal typically runs $300 to $500, though complex or high-value properties can cost significantly more. The fee is non-refundable regardless of the result.
FHA and VA Loans Add Their Own Rules
Government-backed loans layer extra rules on top of the process. If you’re using an FHA or VA loan, a low appraisal creates complications beyond the financing gap.
FHA Loans and the Amendatory Clause
Every FHA purchase contract must include the HUD Amendatory Clause. The clause guarantees you can walk away and recover your earnest money if the appraisal comes in below the purchase price.4U.S. Department of Housing and Urban Development. HUD Amendatory Clause Model Document Buyer, seller, and both agents sign it, and FHA will not insure the loan without it. You may still choose to proceed at the contract price despite the low appraisal, but you cannot be forced to.
The bigger structural issue is that FHA appraisals stay valid for 180 days from the effective date and are tied to the property’s FHA case number, not to your transaction. If your deal falls apart and the seller relists, the next FHA buyer inherits the same low appraisal for the rest of that 180-day window. The appraisal can be updated and extended up to one year from the original effective date, but the initial value stays the starting point.
VA Loans and the Tidewater Process
VA loans have an early warning built in. Under the Tidewater initiative, when a VA appraiser concludes the value will land below the purchase price, they must notify the lender or a designated point of contact before finalizing the report.5U.S. Department of Veterans Affairs. VA Circular 26-17-18 You then have two working days to submit additional comparable sales or supporting data that might change the appraiser’s conclusion. The comparables must be closed sales presented on a standard grid format with MLS documentation.
If the added information doesn’t change the opinion, the appraisal is finalized and a Notice of Value is issued at the lower figure. You can then request a formal Reconsideration of Value through the lender, but the VA limits you to one, and any request seeking more than a 10 percent increase triggers a field review rather than a desk review.6U.S. Department of Veterans Affairs. Reconsideration of Value Request Requirements The Tidewater window is your best shot at influencing the outcome, so have your agent prepare comparables before the appraisal happens, not after.
When the Low Number Is the Right Number
Not every low appraisal is a mistake. Sometimes the appraiser is right, and the contract price genuinely exceeds what the market supports. This happens most often in bidding wars, where emotional competition pushes the price past what comparables justify, and in rapidly shifting markets, where recent sales data hasn’t caught up with asking prices.
If the appraiser used solid comps, made reasonable adjustments, and still landed well below your offer, take that seriously. Paying $20,000 or $30,000 above appraised value means starting with negative equity. You owe more than the home is worth on day one, which limits your ability to refinance, sell, or borrow against the property for years. The appraisal exists to protect the lender, but it protects you too.
