The Quick Read: A low appraisal usually raises the cash you need at closing, and often by more than the size of the gap. Lenders size the loan off the lower of the contract price or the appraised value, so a builder’s price above the appraisal does not raise what the lender will lend against. You cover the shortfall, plus your down payment percentage on the lower value, unless you renegotiate, challenge the value, or exit under your contract.
What Is the “Gap,” and Why Does It Land on You?
The gap is the difference between the contract price and the appraised value. On a purchase, the value used for loan-to-value (LTV) is the lower of the sales price or the appraised value, a rule laid out in the Fannie Mae Selling Guide. Jumbo loans sit outside Fannie Mae and Freddie Mac, and each investor sets its own overlays. Most jumbo programs follow the same logic, but guidelines vary, so treat the agency rule as the reference model rather than the final word.
Jumbo payment estimate
The starting figures are an example price in the jumbo range with ten percent down on a thirty-year fixed. Replace them with yours.
Editable benchmark: 7.40% as of October 15, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a jumbo loan quote.
Illustrative starting assumptions: a $1,000,000 price in the jumbo range, ten percent down on the top-leverage lane, a thirty-year fixed structure at the current Freddie Mac conforming benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conforming benchmark, a market reference and not a jumbo loan quote; jumbo rates are set by the lender and the lane at lock and differ from the conforming benchmark. An adjustable-rate scenario is shown at the benchmark for the whole term; the rate after the initial period is unknown. Reserve months and appraisal counts follow the lane sheet for the amount band; the automated finding may require more. Taxes, insurance and dues are editable estimates; closing costs are not included. On most lanes the conforming limit for the county decides whether a loan is jumbo at all; two lanes start at a stated dollar floor instead. Licensed in sixteen states for consumer mortgages.
This matters more on new construction than on a resale. A builder’s price bundles a base price, a lot premium, and options. The appraiser doesn’t value the bundle. The appraiser values the finished home from closed comparable sales. If the lot premium or the upgrades don’t show up in those comparables, the appraisal lands under the contract.
Frequency is some comfort. A Philadelphia Fed working paper found that fewer than 10% of appraisals in its dataset came in below the contract price, and about 30% matched it exactly. That is 2018 research on mostly resale files, so don’t read it as a forecast for your build. Low appraisals are the exception, but on a large jumbo loan the exception gets expensive.
What Is a Jumbo Loan in This Context?
A jumbo loan starts one dollar above the county’s conforming limit. The Federal Housing Finance Agency (FHFA) resets that limit each year, and it varies by county, so check the FHFA conforming loan limit data for yours. This ties into your down payment in a way many buyers miss: if a resized loan drops below the county limit, the loan can become conforming, and the program changes entirely.
For the borrower, the envelope looks like this across the wholesale programs Lendmire places files with. The headline lane uses a 660 decision score. Leverage reaches 90% on the top lane, with several lanes allowing up to 89.99% combined LTV and the rest stopping at 80%. Loans reach $5,000,000 on the largest lanes. The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lanes, and 43% on the interest-only lanes. Reserves are measured in months of the full payment and rise with the loan amount. All of this is subject to lender guidelines and full file review. Lendmire’s jumbo loan programs are arranged through wholesale lenders, and Lendmire is a broker, not the lender.
How Does the Lender Resize the Down Payment? Step by Step
The resizing follows a fixed order.
1. Contract and plan. You sign with the builder. Your planned down payment is a percentage of that contract price.
2. Appraisal is ordered. An independent appraiser values the home. The CFPB notes that lenders may not interfere with the appraiser’s judgment.
3. The appraiser tests the price. Agency guidance requires appraisers to address market resistance, meaning design, quality, size, or condition that doesn’t fit the competitive market. Closed comparable sales drive the number. Builder incentives get scrutiny.
4. LTV is recalculated. After the appraisal, LTV equals the loan amount divided by the lower of price or value.
5. The maximum loan resets. The program’s maximum LTV applies to the appraised value, not the contract price. The maximum loan becomes that percentage of the lower figure.
6. Your cash requirement is the contract price minus that new maximum loan. That is the key sentence here. You pay the gap dollar for dollar, and you also put down your required percentage on the lower value.
Here is a hypothetical illustration, not a quoted figure. Say a lane caps at 80% of value and the home appraises 5% under contract. You fund the 5% gap, plus 20% of the lower value. Measured against the original price, your cash need is exactly 24% instead of 20%. The shortfall is bigger than the gap because the gap is added on top of a down payment that still has to be paid.
Philadelphia Fed researchers describe a lender’s choices after a negative appraisal: accept the added risk, require a larger down payment to restore the target LTV, or decline. Jumbo lenders lean toward the second.
Where Does the Appraisal Sit in the Build Timeline?
Timing decides which options are still open. On a builder-sold home, the appraisal typically comes after you’ve signed and after the lender has your file. By then you’ve often paid a deposit, picked options, and set a lock. A low number lands when you have the least room to adjust.
You can plan for that. Before signing, read the contract’s appraisal and financing contingency language and its deadlines. Those clauses decide whether you can exit with your earnest money or whether you’re bound to cover the difference. Many buyers focus on the price and skim these paragraphs. Do the opposite.
What Are Your Options When the Value Falls Short?
You have several paths, and they cost different things.
| Option | What it costs you | When it fits |
|---|---|---|
| Pay the gap in cash | Savings and post-closing reserves | You love the home and have liquid cash |
| Renegotiate the price | Builder goodwill | Comparables support the lower value |
| Request a reconsideration of value | Effort, plus time | You have better comparables |
| Trim options or upgrades | Features you wanted | The gap comes mostly from add-ons |
| Split the difference | Cash, shared with the builder | Both sides want the deal |
| Cancel under the contract | The home; deposit depends on terms | Contingency language protects you |
Get the appraisal first and note that a lower value is often a reason to ask the seller for a price reduction. Under the CFPB’s ECOA valuations rule, creditors must give you free copies of appraisals on first-lien home loans, and they must tell you of that right. Ask for the report and read it.
How Does a Reconsideration of Value Work?
A reconsideration of value (ROV) is a formal request that the appraiser take a second look. It’s a review, not a vote, and it doesn’t guarantee a change.
Fannie Mae, Freddie Mac, and HUD standardized the borrower-initiated ROV process for applications dated on or after August 29, 2024, as Consumer Finance Monitor reported. Under Fannie Mae’s framework, the request has to identify the borrower, property address, appraisal effective date, and appraiser. It must describe the areas you think are unsupported or deficient and add supporting data. Fannie Mae’s appraiser update caps additional comparables at five. Pick the five best.
A later Fannie Mae update changed when ROV rights are disclosed. The initial disclosure at application was eliminated, so borrowers now get it when the appraisal is delivered. Jumbo investors set their own ROV policies, so ask your loan officer how the program you’re using handles requests.
An ROV works best with a concrete argument: recent closed sales of similar new homes that the appraiser missed, or an error in square footage or features. “The builder’s price is fair” is not an argument. Neither is “I think it’s worth more.”.
Builder-Sold Homes vs. Self-Built: Where the Gap Comes From
On a builder-sold home, gaps usually come from three places: lot premiums, upgrades, and incentives. A lot premium reflects a view or a corner position that the comparables may not price. Upgrades often cost the builder less than the buyer pays, and an appraiser sees finished value, not the upgrade invoice.
Incentives deserve their own warning. Under Fannie Mae’s interested-party contribution rules, amounts above the allowed maximums count as sales concessions. Items such as furniture, decorator allowances, and moving costs count too. Sales concessions are deducted from the price, and LTV then uses the lower of the reduced price or the appraised value. So a builder credit can shrink your lendable value before the appraisal even comes in low. The guide lists the exact maximums; jumbo investors may differ, so confirm them for your program.
A self-built custom home works differently, because your cost budget and the appraised as-completed value are separate numbers. Construction structures, draws, and land equity each have their own rules, and they vary by lender. If you’re building rather than buying from a builder, ask early which value basis the program uses.
What Does a Larger Down Payment Do to the Rest of Your File?
A bigger down payment ripples outward in four places.
Reserves. Cash you put into the gap is cash that no longer counts as reserves. Reserves on jumbo programs are measured in months of the full payment and rise with the loan amount. A buyer who planned for modest reserves after closing can fall short once the gap eats their savings.
Seasoning and documentation. Extra funds have to be documented. Cash that suddenly appears in an account gets questions. Move money early, and keep the paper trail clean.
Leverage tier. Changing the down payment can move you between leverage tiers. Programs treat leverage up to 80% differently from the higher tiers, and some lanes stop at 80% entirely. Pricing and mortgage insurance needs can shift with the tier. This is program-specific, so the loan officer should walk you through where your resized loan lands. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Loan size. A smaller loan lowers principal and interest, but it drains savings. If the resized loan falls under your county’s limit, you may switch to a conforming program. That could be good or bad depending on the file, so run both paths.
Occupancy also matters. A second home or investment purchase carries lane-specific leverage, so the same appraisal gap can mean a different cash need than on a primary residence. Occupancy decides the leverage.
Where the General Rule Breaks
The “lower of price or value” rule is the default, but a few edge cases bend it.
- Refinance. A refinance is valued on appraised value alone, so there’s no contract price to compare. A low appraisal shrinks the loan without creating a “gap.”
- Affordable-housing exceptions. Fannie Mae allows LTV based on appraised value alone for certain shared-equity and subsidized-price transactions. That isn’t a normal jumbo scenario. It only shows that “lower of” is the default.
- New York. Fannie Mae’s mortgage insurance rules use appraised value for non-co-op property in New York. That’s a narrow agency insurance rule, not a national one.
- Incomplete homes. If the home isn’t finished at appraisal, the report may be “subject to” completion, and the final inspection must support the value.
- Government loans. FHA and VA also base the loan on the lower value. They’re outside the jumbo lane.
- Appraisal waivers. Fannie Mae now calls waivers “value acceptance.” Jumbo loans generally don’t get one, though lenders differ.
Common Misconceptions
“I’m only short by the gap.” Usually you’re short by more, because the cap is a percentage of the lower value and the gap stacks on top.
“The builder’s price sets the value.” The appraiser values from comparable sales. List price doesn’t count.
“Builder incentives are free.” Excess concessions get deducted from the price for LTV purposes.
“I can force a higher number.” An ROV is a review request, not a lever.
“Jumbo rules match conforming rules.” They don’t. Jumbo is investor-specific.
What to Do in the First Few Days After a Low Appraisal
1. Get the full appraisal report and read the comparables and any concession notes.
2. Ask your loan officer for the resized maximum loan and your new cash requirement at the lower value.
3. Check your reserves against the program’s requirement after the added cash.
4. Re-read your contract’s appraisal contingency and note every deadline.
5. Decide whether an ROV has a real chance, meaning you hold better comparables.
6. Talk to the builder about price, options, or credits, and be ready with the appraisal.
7. Check whether the resized loan crosses your county’s conforming limit.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Frequently Asked Questions
Can I just ask the builder to lower the price?
Yes, and it’s often the first step. The appraisal gives you a documented reason. Builders may resist cutting list prices because of other buyers in the community, so they may offer credits or upgrades instead. Credits above allowed limits can count as concessions that reduce lendable value, so ask your loan officer before you accept one.
Do I get to see the appraisal?
Yes. Under the CFPB’s ECOA valuations rule, the creditor must give you a free copy of appraisals and written valuations on first-lien home loans. The creditor must also notify you of that right after you apply, and the exact timing of delivery can vary by file and lender.
Can I bring cash to cover the gap instead of renegotiating?
Usually, yes, if you have the funds documented and your reserves still meet the program’s requirement afterward. The tradeoff is that you’re paying more than the lender says the home is worth. If the comparables later prove the appraiser right, that cash is equity you may not recover soon.
Will a bigger down payment change my loan program?
A bigger down payment can change which program fits. Leverage tiers differ across lanes, and a resized loan may land in a different tier or even fall under your county’s conforming limit. Programs and eligibility are subject to lender guidelines and full file review.
What happens to my deposit if the deal falls through?
That depends on your contract’s appraisal and financing contingency and its deadlines. If you cancel within the contingency terms, you may recover earnest money. If you miss the deadline, you may not. Read those clauses before you sign.
If you are buying a home and want to see whether a jumbo loan fits your file, Lendmire can help you compare the options and what each one asks of the file.
New construction appraisals come down to closed comparable sales, so the buyer who studies those sales before signing a contract knows the likely number before the appraiser does.
