The Quick Read: Yes. A jumbo loan can finance a new-construction home you will live in, because “jumbo” only describes the loan amount. The real question is which path you are on. If the builder is delivering a finished or nearly finished home, a standard jumbo purchase loan usually fits. If the home is not built yet, the loan structure, the appraisal and the timing of your documents all change. Everything depends on the file, subject to lender guidelines and full review.
What Makes a Loan Jumbo?
A loan is jumbo when the amount borrowed is above the conforming limit for the county. The price of the house does not decide it. The loan amount does.
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: 7.32% as of October 22, 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.
FHFA sets the conforming limit each year. It varies by county and by unit count, and Fannie Mae and Freddie Mac cannot buy loans above it. That means a loan that is jumbo in one county can be a conforming loan in another. Check your county before you assume you need a jumbo.
Many move-up buyers land here because their equity is large but the new home still needs a bigger loan than the county allows. Jumbo underwriting is stricter than conforming. Credit, reserves and documentation all get a harder look. Some lenders set a higher credit floor than others, and each sets its own terms.
Lendmire’s jumbo loan programs are arranged through wholesale lenders, and Lendmire is a broker, not the lender. Across the wholesale lanes the network places files with, the headline lane starts with a 660 decision score and reaches leverage up to 90%, with loans up to $5,000,000 on the largest lanes. Several lanes top out at 89.99% combined leverage, and the rest stop at 80%. The ratio ceiling is 50% on the fixed lanes, 45% on the adjustable lane and 43% on the interest-only lanes. All of it is subject to lender guidelines and full file review. Not a commitment to lend.
Which Path Are You On?
New construction changes the process, not the eligibility. There are three common structures, and the right one depends on where the home is in the build.
| Path | Closings | When underwriting happens | Best fit |
|---|---|---|---|
| Finished or spec builder home, standard jumbo purchase | One | Before closing, like any purchase | Home is complete or nearly so |
| One-close construction-to-permanent | One | Up front, with a check at conversion | Ground-up build, one set of fees |
| Two-close construction-only, then a separate mortgage | Two | Twice | Build with uncertain timing or a different final lender |
Finished or nearly finished home. A production builder selling a completed home typically hands you a contract and you take a regular purchase mortgage at closing. This is the simplest route. The loan looks like any jumbo purchase, with a new-construction appraisal.
One-close construction-to-permanent. One closing covers both the build and the long-term loan. Fannie Mae’s Selling Guide describes this structure for loans it buys. The construction phase is a temporary loan, no single construction period may run past 12 months, the total may not pass 18 months, and the permanent term may not pass 30 years.
Here’s the catch. Those limits govern loans delivered to Fannie Mae. A true jumbo is not bound by them. A jumbo investor sets its own construction terms, so ask what the specific program allows before you plan around any of these numbers.
Two-close. You finance the build first, then get a separate mortgage when it ends. The CFPB describes construction loans as usually short-term, with funds released in advances as building progresses. If the loan does not convert on its own, you may have to reapply for a new loan. That reapplication is the main risk of this path.
Will the New Build Count as Your Primary Home?
It counts if you intend to live in it as your main residence, and the file is built to show that. Occupancy drives leverage. Across the wholesale programs the network places files with, primary, second-home and investment occupancy each carry their own lane-specific leverage. Primary residence generally gets the most favorable terms.
For a move-up buyer, the lender looks at the plan. You close, then move in. The file should make sense: where you live now, what happens to that home, and why the new one is the next primary residence. A buyer who keeps the old home as a rental and moves into the new one is still buying a primary. A buyer who plans to rent out the new build is not, and that changes the loan.
Occupancy intent is the line between a primary-residence file and everything else. Don’t blur it on the application.
How Does the Lender Treat the Home You Haven’t Sold?
Usually the existing mortgage payment counts against you until the sale is documented. This is the most common squeeze on a move-up file. You are qualifying for the new loan while the old one is still on the books.
There are three common sequences:
| Sequence | How the old payment is treated | Main risk |
|---|---|---|
| Sell first, then buy | Gone once sold and documented | Gap between homes; temporary housing |
| Buy first, sell later | Typically counted with the new payment | Two payments on the ratio; heavier reserves |
| Coordinated closings | Gone if the sale is documented at or before closing | A delay on either side breaks the timing |
Sell first is cleanest for the file. The ratio only carries one housing payment. The cost is living arrangements, not paperwork.
Buy first can work, but the ratio carries both payments. With a 50% ceiling on the fixed lanes and lower ceilings on the adjustable and interest-only lanes, two payments can push a file over. Reserves, measured in months of the full payment and rising with the loan amount, then matter more. That’s the usual breaking point: income that clears for one payment does not clear for two.
Coordinated closings line up the sale and the purchase. A signed sale contract and a scheduled closing can help, but lenders differ on what they accept. On a new build, the completion date adds a second moving part. If the builder slips, the whole sequence slips.
Equity from your current home can fund the down payment, but cash from a sale does not exist until the sale closes. Some buyers use a cash-out refinance on the current home before buying. Lendmire’s piece on using a cash-out refinance to buy a new primary home walks through that route.
What Builder Timelines Do to a Jumbo File
Long builds age your documents. Credit reports, pay records and asset statements have a shelf life, and a lender may ask for fresh ones at closing or conversion. Fannie Mae’s single-close rules treat older documents as a trigger for requalification. Jumbo investors set their own freshness windows, so plan on updating paperwork if the build runs long, and ask how many months the lender allows.
The related risk is life changing mid-build. A job change, a new debt or a credit event can derail a loan that cleared on day one. Avoid new credit during the build. Keep reserves in the same accounts. Don’t move money around without a paper trail.
Builder contracts add their own pressure. Builders often offer incentives tied to a preferred lender. That is common, but not required. Ask whether the incentive is conditional, and compare Loan Estimates from more than one lender. Builder credits also have limits. For loans sold to Fannie Mae, credits above the allowed caps, or above your actual closing costs, are treated as sales concessions and reduce the price used for the loan. They are not cash back to you. A jumbo investor sets its own caps, so ask before you count on a credit.
Delays matter too. A rate lock only lasts so long. If completion slips, a lock can expire. Ask the builder for a realistic completion window before you commit, and ask the lender how an extension works.
The Appraisal Is Where New-Construction Jumbo Files Get Tight
That is the key point on a new build.
For new or proposed construction, the appraisal can rest on plans and specifications, an existing model home or other information that shows quality and character. Fannie Mae’s Selling Guide lets the lender verify completion with an appraisal update and completion report or a signed attestation. Jumbo investors set their own versions.
Three things make jumbo new-build appraisals harder:
- Thin comparable sales. At higher price points, there are fewer recent sales nearby, and few of them are new.
- Builder incentives. If a price is inflated to fund credits, the appraisal can come in under the contract.
- Two appraisals. Across the wholesale lanes, a second appraisal is required above a lane’s threshold amount.
If the value comes in low, you cover the gap in cash, renegotiate the price or walk, depending on your contract. Look at your contract’s appraisal language before you sign. Upgrades matter too. Design-center spending is often priced above what it adds to appraised value, so plan to pay for much of it in cash rather than count on it inside the loan.
Postponed improvements are sometimes allowed, so a home can close before every item is done, but only within the lender’s own criteria. Don’t assume it.
When a Jumbo Is the Wrong Tool
A jumbo loan is not always the answer. Run through these before you write an offer:
- Your loan fits under the county limit. A conforming or high-balance loan may be simpler. Check the FHFA county list first.
- You need more leverage than the lane offers. Leverage above 80% exists on only some lanes, and the rest stop at 80%.
- The build will run long. A long timeline raises the odds of requalification, expired documents and lock problems.
- You can’t carry two payments. If you must buy before you sell, and the ratio fails with both payments, wait or sequence differently.
- You plan to rent the home. Then it is not a primary residence, and the file changes.
- Condos. Fannie Mae makes attached condo units and co-ops ineligible for construction-to-permanent financing, though detached condo units can be allowed. Two of the wholesale jumbo lanes accept non-warrantable condominiums, but a new-construction condo project still gets its own review.
Key Terms Defined
Conforming loan limit: The county-specific maximum loan size that Fannie Mae and Freddie Mac can buy. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Construction-to-permanent loan: A single loan that funds the build and then turns into a long-term mortgage.
Draw: A release of construction loan money as building progresses.
Appraised value: The lender’s opinion of the home’s worth, which caps the loan regardless of the contract price.
Reserves: Cash or liquid assets left after closing, measured in months of the full housing payment.
Sales concession: A seller or builder credit above the allowed limit, treated as a price reduction for loan purposes.
A Pre-Offer Checklist
1. Confirm whether your loan amount is above your county’s conforming limit.
2. Decide which path you are on: finished home, one-close or two-close.
3. Plan the sale of your current home and how the old payment will be treated.
4. Ask the builder for a realistic completion window and the lock length that fits.
5. Read the appraisal language in the contract.
6. Ask whether any builder incentive depends on a preferred lender.
7. Gather income, asset and credit documents, and expect to refresh them.
8. Compare Loan Estimates from more than one lender.
Down payment help is a separate question on new builds. Lendmire’s article on using down payment assistance on a new-construction home covers what that looks like.
Frequently Asked Questions
Do I have to sell my current home first?
No. But the old mortgage payment is typically counted unless the sale is documented. Buying first means the ratio carries two payments, and reserves matter more. Selling first or lining up closings keeps the file simpler.
Can I use the builder’s lender?
You can, but no federal rule requires it. Builder incentives are sometimes tied to a preferred lender, so ask whether the incentive is conditional. Compare Loan Estimates from more than one lender before deciding.
What if the appraisal comes in low?
The loan is based on appraised value, not the contract price. A low appraisal usually means you bring more cash, renegotiate the price or walk away if your contract allows. Read the appraisal clause before you sign.
Can I finance upgrades?
Only up to what the appraisal supports. Design-center spending often adds less value than it costs, so much of it ends up paid in cash.
Do I have to requalify after the build?
It depends on the structure. A one-close loan is meant to convert without a new loan, but lenders can ask for refreshed documents, and a change in income, job or credit during a long build can cause trouble. On a two-close path you apply for a new mortgage when the build ends.
