An appraisal gap is the difference between what you agreed to pay for a home and what the appraiser says it’s actually worth — and it can kill your deal if you’re not prepared.

Say you offered $375,000 on a house. The bank sends an appraiser who determines the home is worth $350,000. That $25,000 difference is the appraisal gap. Your lender won’t finance more than the appraised value, so someone needs to cover that $25,000 — and usually it’s you.

Why Appraisal Gaps Happen

Bidding wars. That’s the short answer. In competitive markets, buyers offer above asking price to win. But appraisers base their valuation on recent comparable sales, not buyer enthusiasm. If comps support $350,000, the appraiser isn’t going to stretch to $375,000 just because three buyers offered that much.

Appraisal gaps also pop up when the market moves faster than comps can keep up. If prices jumped 8% in two months, the appraiser might still be using sales from 90 days ago that don’t reflect current conditions.

Appraisal Gap Coverage

Appraisal gap coverage is a clause in your offer that guarantees you’ll pay the difference in cash. It tells the seller: “Even if the appraisal comes in low, I’ve got $15,000 (or whatever amount) to bridge the gap.”

This makes your offer much stronger in competitive situations. Sellers hate appraisal gaps because they can delay or torpedo the sale. A gap coverage clause removes that risk for them.

Here’s how the math works on a $375,000 offer with $15,000 in gap coverage:

  • Appraisal: $365,000. Gap is $10,000. You pay $10,000 cash (within your $15,000 limit). Deal proceeds
  • Appraisal: $350,000. Gap is $25,000. Your coverage handles $15,000, leaving $10,000 unresolved. You and the seller need to negotiate that remaining $10,000
  • Appraisal: $375,000. No gap. Your coverage clause doesn’t cost you anything

Watch out for: Unlimited gap coverage (waiving the appraisal contingency entirely). You’re promising to pay whatever the seller asks regardless of what the home is worth. Only do this if you can genuinely afford to lose that money or if the gap is likely small.

When to Walk Away

Not every deal is worth saving. Consider walking if:

  • The gap exceeds 5%–7% of the purchase price — you’re overpaying by a meaningful margin
  • You’d need to drain your emergency fund to cover it
  • The appraisal flagged issues beyond just value (condition problems, declining neighborhood)
  • The seller won’t budge on price at all despite a low appraisal

Your inspection contingency won’t help here, but your appraisal contingency will — as long as you didn’t waive it. With the contingency intact, you get your earnest money back and move on.

Frequently Asked Questions

Does appraisal gap coverage increase my loan amount?

No. The gap coverage is cash out of your pocket, separate from your mortgage. Your loan stays based on the appraised value (or purchase price, whichever is lower). So if you offered $375,000 with 10% down and the appraisal came in at $350,000, your loan is based on $350,000 — meaning you borrow $315,000 and bring $60,000 cash ($35,000 down payment on appraised value + $25,000 gap). That’s a lot of cash. Run the numbers through our affordability calculator before committing to any gap coverage amount, and read the full buying guide for more on structuring competitive offers.
