The appraisal comes back $18,000 below purchase price. Your buyer's phone blows up. The listing agent goes silent. And now you have a deal that was days from closing suddenly back on the edge.
Low appraisals are disruptive, but they're rarely fatal — if you know what to do. The agents who handle them well aren't lucky. They're prepared. They understand the contract language, they know how to read an appraisal report, and they have a clear sequence of moves before the panic sets in.
Here's that sequence, from the moment you get the bad news to the moment the deal either closes or terminates cleanly.
Check the appraisal contingency before you do anything else
The first thing you need to know is what the purchase agreement actually says about appraisal. Does the contract include an appraisal contingency? Is there an appraisal gap coverage clause — and if so, how much is the buyer contractually committed to cover out of pocket? Some contracts waive the appraisal contingency entirely; others cap the buyer's gap obligation at a specific dollar amount. You cannot strategize around a low appraisal without knowing your contractual footing. Pull the contract, find the appraisal language, and know exactly where your client stands before you make any phone calls.
Get a copy of the appraisal report and actually read it
Lenders are required to provide buyers with a copy of the appraisal. Get it. Don't just look at the final number — read the comparable sales (comps) the appraiser used to reach their value. Are they accurate? Were they truly comparable in size, condition, and location, or did the appraiser pull comps from a different neighborhood because recent sales in the subject area were limited? Check the date range of the comps too. In a fast-moving market, sales from six months ago can significantly underrepresent current value. These details matter because they're the foundation of any challenge you might want to raise.
Request a reconsideration of value — with evidence
If you believe the appraisal is wrong, you can formally request a Reconsideration of Value (ROV) through the lender. This is not a complaint — it's a structured appeal backed by data. Compile two to four recent comparable sales that the appraiser missed or overlooked, and explain in writing why each comp is more representative than what was used. Include MLS data, square footage, lot size, age, and condition notes. An ROV doesn't always work, but when the appraisal used weak comps or missed a clear sale nearby, it's worth the effort. The lender forwards your evidence to the appraiser, who then reviews and either maintains or adjusts their value.
Negotiate a price reduction with the seller
If the ROV isn't an option or doesn't succeed, the next move is renegotiating the purchase price. The seller now has a problem too: their property appraised below contract price, which means most buyers with financing can't proceed at the original number unless they bring extra cash. Remind the listing agent of this reality — it's not a buyer tactic, it's a lender constraint. Propose a price that meets the appraised value, or at least splits the gap in a way both sides can live with. Sellers in competitive markets are sometimes willing to hold firm; sellers who are motivated, who have already purchased elsewhere, or who are facing a timeline will often negotiate.
Explore whether the buyer can cover the gap
If the seller won't come down and the buyer has the means, covering the appraisal gap in cash is a legitimate path forward. The buyer pays the difference between the appraised value and the purchase price out of pocket — in addition to their normal down payment. Before this becomes the plan, confirm a few things: Does the buyer actually have the liquidity? Will covering the gap leave them short on reserves? Is the property worth it to them at the higher effective cost? Sometimes the answer is yes — especially in tight markets where the buyer has already lost multiple offers. But this is a financial decision, and your buyer should make it with clear numbers in front of them, not in a moment of emotional pressure.
Exercise the appraisal contingency if the deal doesn't work
If the seller won't negotiate, the buyer can't or won't cover the gap, and the ROV went nowhere, the appraisal contingency is there to protect your client. A properly executed appraisal contingency allows the buyer to terminate the contract and recover their earnest money if the property appraises below purchase price and the parties can't reach a new agreement. This is not a failure — it's the contingency doing exactly what it was designed to do. What is a failure is missing the contingency deadline. Know when it expires, act within it, and document every step. An appraisal dispute resolved verbally but never put in writing leaves everyone exposed.
The appraisal contingency deadline is not flexible
Every path above — ROV, price renegotiation, gap coverage, or termination — has to happen within the appraisal contingency window. Miss it, and your buyer may lose their right to walk. In some contracts, failing to act within the contingency period means the buyer is obligated to proceed at the original purchase price regardless of what the appraisal said.
Appraisal contingency deadlines vary. Some run from the acceptance date, some from the appraisal delivery date, some from when the buyer receives the report. Know which one you're working with. Know the exact calendar date. Set a reminder before the deadline, not the morning of.
If negotiations drag on and you're approaching the deadline without resolution, a short extension addendum is almost always worth requesting. It buys time without waiving protections. Most sellers and listing agents will agree — they want the deal to close too.
The one scenario agents overlook: the seller-side low appraisal
Most of this article assumes you're representing the buyer. But listing agents face low appraisals too — and the dynamic is different. Your seller doesn't have a contingency to exercise. What they have is a negotiation.
As a listing agent, your job when the appraisal comes in low is to gather the same comps the appraiser missed and make the case — professionally, through the buyer's agent and lender — that the value is defensible. You can also request that the seller hold firm and invite the buyer to cover the gap, particularly if your seller has leverage (low inventory, multiple backup offers, a property with unique features that don't comp easily).
What you can't do is pressure the appraiser directly. That crosses a legal line. Your influence runs through the lender's formal ROV process, through documented comps, and through your negotiating posture with the other side. Stay in those lanes and you'll protect your client — and yourself.
