You agreed on a price, your offer was accepted — and then the lender's appraisal comes back below what you agreed to pay. That gap can stall or sink a deal, because lenders won't lend on more than the home is worth. The appraisal gap is one of the most stressful surprises in a purchase, and one of the most misunderstood. Here's exactly what it means and what your options are.

Why the appraisal matters to your loan
Your lender orders an independent appraisal to confirm the home is worth what you're borrowing against. They'll lend based on the lower of the purchase price or the appraised value — never more. So if you agreed to $410,000 but the home appraises at $390,000, the lender treats $390,000 as the value, and the $20,000 difference is the appraisal gap you have to solve.
Your three options
When a gap appears you generally have three moves. One: cover the difference in cash on top of your down payment, if you have it and the home is worth it to you. Two: renegotiate with the seller to lower the price to the appraised value, or meet somewhere in the middle. Three: if your contract has an appraisal contingency, walk away and keep your earnest money. Which works best depends on your finances and how badly each side wants the deal.
Appraisal gap clauses and waivers
In competitive markets, buyers sometimes strengthen an offer with an 'appraisal gap clause' promising to cover a shortfall up to a stated amount, or by waiving the appraisal contingency entirely. These make an offer more attractive to sellers — but they shift real financial risk onto you. Never waive an appraisal contingency or commit to covering a gap without understanding exactly how much cash you'd need if the number comes in low.
How an agent helps you navigate it
A good agent prices offers to reduce gap risk in the first place, knows when an appraisal can be reasonably disputed, and negotiates the split when a gap appears. On the seller side, they help you weigh holding firm versus keeping a qualified buyer. RESMP matches you with verified local agents who handle appraisal gaps as routine — so a low number becomes a negotiation, not a dead deal.
Frequently Asked Questions
What is an appraisal gap?
It's the difference between the price you agreed to pay and the (lower) value the lender's appraisal assigns. Because lenders finance against the lower of price or appraised value, that gap has to be solved for the deal to close.
What are my options if the home appraises low?
Generally three: pay the difference in cash, renegotiate the price down with the seller, or — if you have an appraisal contingency — walk away and keep your earnest money. The best move depends on your finances and the seller's motivation.
Should I waive the appraisal contingency to win a bid?
Only with caution. Waiving it (or adding a gap-coverage clause) strengthens your offer but puts real cash at risk if the appraisal comes in low. Never do it without knowing exactly how much you'd need to cover. An agent can advise.
