What happens if the appraisal comes in low? The appraiser's written opinion of value is below the price in the sales contract, and loan size is tied to value. Under the Fannie Mae Selling Guide, the property value used to set the loan-to-value ratio on a purchase is the lower of the sales price or the appraised value. That leaves a gap between the contract price and what the loan supports. The Consumer Financial Protection Bureau (CFPB) warns that "it is very risky to purchase a home for more than the appraised value."
This guide explains why the loan changes, shows with a labeled illustration how large the gap can become, and lists the ways the CFPB says a gap can be handled. It is general information about US home purchases, not advice about any transaction.
What an appraisal is, and what it is not
The CFPB defines an appraisal as "a written document that shows an opinion of how much a property is worth" in its answer on what appraisals are and why a borrower should look at them (last reviewed September 4, 2020, read October 3, 2026). It is usually compared against similar nearby sales, often called comps. It is an opinion of market value on a given date, not an inspection of the home's condition and not a verdict on whether the price was fair to the buyer.
An appraisal is also only one kind of valuation. The CFPB's page on why a borrower can receive different valuations (last reviewed June 27, 2024, read October 3, 2026) lists three: appraisals by licensed appraisers, broker price opinions from real estate professionals, and automated valuation models that produce a computer-generated estimate. It explains that valuations can differ because "they are estimates and may be based on different comps or may have been completed at different times or for different purposes." A listing price, a tax assessment and an appraisal can therefore each show a different number for the same house.
A homeowners policy has its own idea of value too, and it is not the same thing as appraised market value. Our guide to actual cash value vs replacement cost explains how insurers use value on the policy side.
What happens if the appraisal comes in low
A mortgage lender sets the loan against a value it can support. The Fannie Mae Selling Guide (page dated June 1, 2022, read October 3, 2026), which sets standards for many conventional loans, says to "divide the original loan amount by the property value," and defines the property value as "the lower of the sales price or the current appraised value."
So when the appraisal is below the price, the lower number is the one that counts. Three things follow.
- The loan can shrink. If the lender holds its loan-to-value limit, the maximum loan falls with the appraised value.
- The cash needed at closing can rise. The buyer still owes the contract price, so any amount the loan no longer covers has to come from somewhere else.
- The contract is now in question. The price is the agreement between seller and buyer, and the appraisal is the lender's input. They no longer match, so one of them has to move or the deal can stop.
Programs differ. Loan types and lenders set their own limits, and this guide does not cover every one of them. The mechanism above is the common thread.
How big the gap gets: a labeled illustration
A common assumption is that a $20,000 shortfall costs the buyer $20,000. The figures below are an illustration with assumed inputs, not a prediction. The assumptions are a $400,000 contract price, an appraisal of $380,000, and a lender that sizes the loan at a fixed loan-to-value ratio on the lower of price or appraised value, as in the Fannie Mae calculation above. The two ratios, 95 percent and 80 percent, were chosen only to show a small and a large down payment. Closing costs, mortgage insurance and program rules are left out.
| 95% loan-to-value | 80% loan-to-value | |
|---|---|---|
| Loan if the appraisal matched the $400,000 price | $380,000 | $320,000 |
| Cash toward the price in that case | $20,000 | $80,000 |
| Loan with an appraisal of $380,000 and the price unchanged | $361,000 | $304,000 |
| Cash toward the price after the low appraisal | $39,000 | $96,000 |
| Extra cash compared with the original plan | $19,000 | $16,000 |
| Loan if the price is lowered to $380,000 | $361,000 | $304,000 |
| Cash toward the price at $380,000 | $19,000 | $76,000 |
The arithmetic shows two things the common explanations leave out. The shortfall lands on the buyer at nearly the same size as the appraisal gap, because the lender covers only its percentage of the lower value. And the smaller the down payment, the larger the share of the gap that falls on the buyer, because the lender's percentage is higher. In the illustration, a price reduction equal to the shortfall brings the loan and the cash needed back in line with the original plan.
Real transactions have more moving parts, so the figures for any actual loan come from the lender's own written estimate.
The ways a gap gets handled
The CFPB's consumer answer on an appraisal that is less than the sale price (last reviewed September 11, 2024, read October 3, 2026) names three steps in order: get the appraisal, negotiate with the seller, and consider cancelling. The table sets those next to the cash option that the arithmetic above implies.
| Path | What the source says | What it turns on |
|---|---|---|
| Review the report | The CFPB says to request a copy from the lender and describes the appraisal as "a professional opinion as to the value of the home." | Whether the comps and property details are accurate |
| Ask the seller to lower the price | "The appraisal is strong evidence that the price was above the market value." | The seller's agreement, which the seller is free to refuse |
| Cover the difference with cash | Follows from the loan-to-value mechanism above | The buyer's own funds, and the CFPB's warning about paying above appraised value |
| Cancel the purchase | If the seller will not reduce the price, the CFPB says to explore cancelling with an attorney, and that the costs "are likely small compared to buying a home that isn't worth what you paid for it" | The contract terms, which an attorney can review |
A buyer's rights depend on the purchase agreement and state law, and this guide cannot say what a particular contract allows.
The right to see the appraisal
The CFPB's appraisal answer linked above says a borrower is entitled to a copy of the appraisals the lender obtains, and that the copy is due promptly after the appraisal is completed and no later than three days before closing. It adds that a borrower "can't be charged a fee for copies of an appraisal or other valuation," although the lender can charge "a reasonable fee for the lender's cost of preparing the appraisal or other valuation."
The report matters because it shows the comparable sales behind the number. A buyer who wants the figure reconsidered is looking at that list of comps and the property details. Whether a lender will review an appraisal, and how, is the lender's own process, so the loan officer is the person to ask.
What changes if the loan or the price changes
A lower loan amount or a changed price can affect other numbers on the mortgage paperwork, including the estimated cash to close. The Loan Estimate and the Closing Disclosure show the figures that apply to a specific loan, so a revised version from the lender is the place to see the new totals.
Who can help with a specific appraisal
The loan officer can explain how the lender is treating the appraisal and what the revised loan terms would be. A real estate attorney can review what the purchase contract says about price changes and cancellation in the buyer's state. A HUD-approved housing counselor can walk through the mortgage forms. Each will want the appraisal report, the purchase contract and the most recent Loan Estimate.
Frequently asked questions
What happens if the appraisal comes in low?
The appraised value is below the contract price. Under the Fannie Mae calculation, the lower of the two is the value used for the loan-to-value ratio, so the loan the lender will make can fall below what the original plan assumed.
Does the buyer have to cover the gap in cash?
Not necessarily. The gap can also be closed by a lower price, by another agreement between buyer and seller, or by cancelling under the contract. The CFPB lists negotiating with the seller as a step, and notes that the appraisal is strong evidence the price was above market value.
Can the buyer get a copy of the appraisal?
Yes. The CFPB says a borrower is entitled to a copy of the appraisal the lender obtains, promptly and no later than three days before closing. The lender can charge a reasonable fee for the cost of preparing it, but not a fee for the copy.
Is it safe to pay more than the appraised value?
The CFPB calls it "very risky" to buy a home for more than the appraised value. Whether it is workable for a particular buyer depends on that buyer's finances and contract, and a lender or attorney can speak to the specifics.
Does a low appraisal mean the home is a bad purchase?
Not by itself. It is one appraiser's opinion based on the comparable sales and property details available on a date. The CFPB notes that valuations can differ because they may use different comps or be done at different times.
Federal guidance and lender standards can change. The details in this article were checked against the CFPB pages and the Fannie Mae Selling Guide cited above on October 3, 2026.
