Appraisal gap: what happens when the home appraises below your offer

You offered $420,000; the appraiser says $400,000. The lender will finance a percentage of $400,000, not $420,000. That $20,000 is the appraisal gap, and it is your problem to solve in the next few days.

Why it happens

Appraisers value a home from recent comparable sales. In a rising or bidding-war market, contract prices outrun closed sales, so appraisals lag. Unusual homes, rural areas with few comps, and rapidly changing neighborhoods produce gaps more often. The appraisal is ordered by the lender and paid by you, but the appraiser works independently.

The math

With 10% down on $420,000 you planned to borrow $378,000 and bring $42,000. On a $400,000 appraisal the lender caps the loan at 90% of $400,000 = $360,000. To close at $420,000 you now need $60,000 — the original $42,000 plus the $20,000 gap — or you renegotiate.

Your five options

Pay the gap in cash. Only if you have it after reserves and closing costs.
Renegotiate the price. Sellers often meet in the middle, especially if the backup offers were also financed and would face the same appraisal.
Split the difference — partial price cut, partial cash.
Challenge the appraisal. A “reconsideration of value” with better comps the appraiser missed; success is uncommon but real when there is a factual error.
Walk away under an appraisal contingency and recover your earnest money. Without the contingency, walking away forfeits the deposit.

Appraisal gap clauses

In competitive markets buyers offer to cover a gap “up to $X” in advance. Write it with a cap you can actually fund, and keep the appraisal contingency for anything beyond the cap. Never promise to cover an unlimited gap.

Lender-specific wrinkles

FHA and VA appraisals stay with the property for a period (an FHA appraisal for 120 days), so a second buyer with the same loan type inherits the value. VA buyers get a formal “Tidewater” process to submit comps before a low value is finalized. Conventional lenders may use an appraisal waiver on strong files, in which case no gap can arise.

Frequently asked questions

Can I get a second appraisal?

Only if the lender orders it — usually when the first has a demonstrable error or the lender’s own review flags it. You cannot simply hire your own appraiser and substitute the report.

Does a low appraisal mean I am overpaying?

Not necessarily; it means recent closed sales do not yet support the price. In a rising market that can reverse within months. In a flat or falling market, take it seriously.

Who pays for the appraisal if the deal dies?

You do — the fee is paid when ordered and is not refundable.
