What Is an Appraisal Gap, and How Do You Cover It in a Competitive Offer?

An appraisal gap happens when the lender's appraiser values a home lower than the price you agreed to pay for it — and because your mortgage is based on that appraised value, not your offer price, the difference becomes cash you have to come up with if you still want the house. In a Los Angeles County market where well-priced homes still pull multiple offers, agreeing up front to cover a set amount of that gap is one of the most effective ways to make your offer competitive without blowing your entire budget on price alone.

Why Would a Home Appraise for Less Than the Purchase Price?

Appraisers are required to base their value on recent closed sales of comparable homes nearby — not on what buyers are currently willing to pay. In a fast-moving market, pending sales and new listings can push prices up faster than the closed comps can catch up, which creates a gap. It's especially common across Los Angeles County's older neighborhoods, where lot size, permitted square footage, and renovation quality vary block to block and make "comparable" homes harder to find. The lender orders the appraisal independently, so neither you nor the seller has any control over the number that comes back.

How Does an Appraisal Gap Clause Actually Work in an Offer?

A standard California purchase contract gives buyers an appraisal contingency, typically around 17 days, that lets you cancel or renegotiate if the home appraises low. An appraisal gap clause adjusts that protection: you agree in writing to cover a specific dollar amount (or percentage) above the appraised value in cash if needed, and your contingency only kicks back in beyond that point. For example, if you offer $850,000 and agree to cover a $20,000 gap, but the home appraises at $810,000, you'd bring an extra $20,000 to closing to bridge most of that $40,000 shortfall, and you'd still have the right to renegotiate or walk away from whatever's left uncovered.

How Much Should You Agree to Cover?

This comes down to what's actually sitting in your bank account beyond your down payment, closing costs, and a reasonable reserve — never a number pulled out of thin air to "win" the offer. Across competitive pockets of LA County, buyers are typically agreeing to cover somewhere between $10,000 and $25,000, or roughly 1% to 3% of the purchase price, though it varies a lot by neighborhood and how many offers a home is drawing. With 30-year mortgage rates averaging 7.28% as of early October 2026 according to Freddie Mac, most buyers are already stretched on their monthly payment, so run the numbers with your lender first and set a firm cap before you ever write the offer.

What Are Your Options If the Appraisal Still Comes in Low?

If the gap turns out to be bigger than what you agreed to cover, you generally have four paths: ask the seller to lower the price to match the appraisal, pay the remaining difference in cash if you're able to, have your agent submit a Reconsideration of Value to the lender if you believe the appraiser missed relevant comps, or walk away and get your earnest money back, which is typically 1% to 3% of the purchase price in Los Angeles County, as long as your appraisal contingency is still active for that amount.

Should You Ever Waive Your Appraisal Contingency Completely?

Waiving it entirely means you're obligated to close at the agreed price no matter what the home appraises for, with no contractual way out if the gap is larger than expected. That's a real risk, and it only makes sense for buyers with significant cash reserves well beyond what they'd need for a defined gap clause. With Redfin reporting the median Los Angeles County home now taking about 49 days to sell as of August 2026, up from the frantic pace of a few years ago, most agents — myself included — recommend a capped gap clause instead of a full waiver. It keeps your offer strong without leaving you financially exposed.

Frequently Asked Questions

Does a low appraisal only hurt buyers?
No — on the flip side, an appraisal that comes in at or above your offer price gives you instant equity from day one, which can help later if you refinance or want to borrow against the home.

Can I just get a second appraisal if the first one comes in low?
You can ask your lender for a Reconsideration of Value, where your agent submits additional comparable sales the appraiser may have missed. A full second appraisal is less common and depends on your lender's policy.

Does the money I use to cover an appraisal gap count toward my down payment?
No, it's treated as separate cash needed to close, on top of your down payment and closing costs, so your lender will want to see it sourced and seasoned in your accounts just like the rest of your funds.

Is waiving the appraisal contingency riskier right now than it used to be?
With mortgage rates near 7.3% and homes sitting on the market longer than they did a couple of years ago, inventory isn't as tight as it was during the pandemic years, so for most buyers the downside of waiving outweighs the upside of looking more competitive.
