Appraisal Contingency in California: Gaps, Low Appraisals and ROVs
An appraisal contingency lets a California buyer cancel or renegotiate a purchase if the property appraises below the price. In the C.A.R. residential purchase agreement it’s a separate contingency from the loan contingency, with its own time period that the offer can shorten, lengthen or waive. The difference between the price and a lower appraised value is the appraisal gap, and whoever covers it, whether buyer, seller or both, is a matter for negotiation.
A low appraisal matters because lenders lend against value, not price. In competitive North Bay and Bay Area markets, buyers often offer to cover some or all of a gap to make an offer stronger. This guide explains how the contingency works, the cash math of a gap, how to ask the lender for a reconsideration of value, and what each side can do when the number comes in low. For the contract as a whole, see our guide to the California residential purchase agreement.
How the appraisal contingency works
When you finance a purchase, the lender orders an appraisal to confirm the property supports the loan. The appraisal contingency protects you if it doesn’t: within the contingency period, you can ask the seller to lower the price, agree to cover the difference, or cancel under the contract’s terms.
- It’s separate from the loan contingency. The loan contingency covers whether you get the loan at all. The appraisal contingency covers the value. You can keep one and remove the other.
- It has its own deadline. The period runs from acceptance. C.A.R. updates its forms, and the guides to them are for members, so read the current form for the default period, and use our contract deadline calculator to track the dates.
- Removing it has consequences. Once the contingency is removed or expires under the contract, a low appraisal alone usually isn’t a reason to cancel, and your earnest money deposit may be at risk. If the seller thinks you’re late, they may use a notice to perform.
Cash buyers have no lender appraisal, but a buyer paying cash can still order an appraisal and make the purchase contingent on it if the seller agrees.
The appraisal gap: the cash math
Lenders generally size a loan on the lower of the price and the appraised value, so a gap usually means more cash at closing, not just a smaller loan. Confirm how your lender treats it. Here’s an illustration with a 20% down payment.
| Line | Appraises at price | Appraises $50,000 low |
|---|---|---|
| Purchase price | $1,000,000 | $1,000,000 |
| Appraised value | $1,000,000 | $950,000 |
| Loan at 80% of value | $800,000 | $760,000 |
| Cash needed for price (before closing costs) | $200,000 | $240,000 |
In this example the buyer needs $40,000 more to keep the same loan-to-value ratio. The alternative is to keep the $800,000 loan, which is about 84% of the appraised value; that may change the rate or add mortgage insurance, so ask your lender to price both. The numbers are hypothetical, and your loan program’s limits and costs will differ.

Appraisal gap coverage in an offer
Gap coverage is a promise in the offer to pay some or all of the difference if the appraisal comes in low. It’s usually written in one of three ways:
- A capped amount. The buyer agrees to pay up to a stated dollar amount over the appraised value, and keeps the contingency for anything beyond it.
- Full coverage. The buyer agrees to pay the full price whatever the appraisal, which in practice removes the appraisal contingency.
- A split. Buyer and seller agree in advance how they’ll share a gap.
Write the terms precisely: the dollar cap, whether the buyer keeps the right to cancel above it, and how the cap interacts with an escalation clause, since an escalated price is the one most likely to exceed the appraisal. Have your agent and, where needed, a real estate attorney review the wording before you sign.
Only promise what you can pay. Gap coverage is cash on top of your down payment and closing costs, and lenders generally won’t lend it. Our guide to winning a multiple-offer situation covers the other levers.
Should you waive the appraisal contingency?
Waiving it tells the seller the price won’t be renegotiated on appraisal. That can win a house, but you take on the gap with no cap. Before you waive, ask:
- How much cash could I add if the appraisal came in 5% or 10% low?
- Do the recent comparable sales support the price, or am I paying above them?
- Is my loan contingency still in place, and how does my contract treat a loan denial caused by value?
- Would capped gap coverage be nearly as attractive to this seller?
Our overview of why contingencies matter explains how each one protects you.
Challenging a low appraisal: reconsideration of value
If you believe an appraisal missed something, you can ask the lender for a reconsideration of value (ROV). Fannie Mae and FHA both set rules for borrower requests in 2024.
| Rule | Fannie Mae conventional loans | FHA loans |
|---|---|---|
| Where it’s set | Selling Guide B4-1.3-12, Appraisal Quality Matters; requirements published May 1, 2024 | Mortgagee Letter 2024-07, issued May 1, 2024; required for case numbers assigned on or after September 2, 2024 |
| How many requests | One ROV for each appraisal report | One borrower-initiated ROV per appraisal |
| Alternative comparable sales | Per the lender’s form | No more than five |
| Who handles it | The lender, on forms with the information the Selling Guide requires | The underwriter reviews the request before contacting the appraiser |
| Timing | Ask your lender | Must be resolved before closing; lenders disclose the process at application and when the appraisal is delivered |
How to make a strong request:
- Get the full report. Read the square footage, bedroom and bathroom count, lot size, condition rating and the comparable sales used.
- Check the facts. Errors in size, room count or permitted additions are the easiest to fix. Provide permits or plans as proof.
- Offer better comparables. Your agent can pull closed sales that are closer in location, size, age and date, and explain why they fit better.
- Submit through the lender. Use the lender’s ROV process and keep to its deadlines; don’t contact the appraiser directly.
- Keep your contract dates in view. An ROV can take time. If it may run past your contingency deadline, ask the seller in writing for an extension.
Appraisal bias has its own route. Since July 1, 2022, Civil Code section 1102.6g has required every California contract for the sale of real property to include a notice that appraisals must be unbiased and objective. A buyer or seller who believes an appraisal was influenced by race, religion, disability or another protected characteristic can report it to the lender or mortgage broker that hired the appraiser and file a complaint with the Bureau of Real Estate Appraisers.
Options when the appraisal comes in low
| Option | Who gives | When it fits |
|---|---|---|
| Seller reduces the price to the appraisal | Seller | Comparable sales support the appraisal, and other buyers would face the same number |
| Buyer pays the gap in cash | Buyer | The buyer has cash and believes the price is right |
| Split the gap | Both | Each side wants the deal more than the difference |
| Change the loan structure | Buyer | A higher loan-to-value ratio is available at an acceptable cost |
| Request a reconsideration of value | Buyer, through the lender | The report has factual errors or missed better comparable sales |
| Cancel under the contingency | Buyer | The contingency is still in effect and no agreement is reached; see cancelling a home purchase in California |
For sellers: pricing so the appraisal holds
An appraiser works from closed sales, not from offers. If your price rests on a bidding war, expect the buyer’s lender to test it. Price from recent closed sales; our comparative market analysis guide explains how.
When you compare multiple offers, weigh the appraisal terms with the price: a slightly lower offer with real gap coverage, or a larger down payment, may be more likely to close. Give the appraiser a list of upgrades with permits and the sales you think are most comparable, through your agent.
If an appraisal does come in low, ask whether the buyer will pursue a reconsideration of value, compare the appraisal’s comparables with your own, and decide whether another buyer’s lender is likely to reach a different number.
Questions people ask
What is an appraisal contingency?
A term in the purchase contract that lets the buyer cancel or renegotiate if the property appraises below the price, within a set period after acceptance. In the C.A.R. form it’s separate from the loan contingency.
What is an appraisal gap?
The difference between the purchase price and a lower appraised value. Because lenders generally lend on the lower of the two, the buyer usually has to cover the gap in cash or renegotiate.
Can I back out if the appraisal is low?
Yes, if your appraisal contingency is still in effect, following the contract’s notice requirements. Once it’s removed or has expired under the contract, a low appraisal alone usually isn’t grounds to cancel.
Is it a good idea to waive the appraisal contingency?
Only if you can pay any gap in cash and you’re comfortable with the price against recent sales. Capped gap coverage is often a middle ground.
How many times can I ask for a reconsideration of value?
For Fannie Mae and FHA loans, one borrower-initiated request per appraisal. FHA limits the request to five alternative comparable sales and requires it to be resolved before closing.
Does the seller have to lower the price after a low appraisal?
No. The seller can refuse; the buyer’s remedy, while the contingency is in effect, is to cover the gap, negotiate or cancel under the contract.
Who chooses the appraiser?
The buyer’s lender orders the appraisal, and neither the buyer nor the seller picks the appraiser. Questions and ROV requests go through the lender.
