The Quick Read: Buyers who need to close on the next home before the current one sells usually fund the down payment from savings, borrowed equity, a bridge loan, or sale proceeds once those exist. The percentage down matters, but the old home’s payment and the buyer’s reserves often decide the file. Proceeds from a home that has not closed are an estimate, not cash. Lenders count them only when documented.
What Makes a Loan “Jumbo” for This Buyer?
A loan is jumbo when the loan amount, not the purchase price, sits above the conforming limit for the county. A big down payment can pull a high-priced purchase back under the line.
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.
That limit is set by county. FHFA publishes the conforming loan limit values, including a county list and a map, and the baseline is higher in high-cost areas. Don’t treat any single national figure as the jumbo line. Look up the county.
Across most of the wholesale lanes we place files with, a jumbo loan begins one dollar above the county limit. The headline lane runs on a 660 decision score, leverage to 90%, and loans up to $5,000,000. Several lanes reach 89.99% combined loan-to-value. The rest stop at 80%. The fixed lanes allow a 50% ratio ceiling, while the adjustable lanes cap at 45% and the interest-only lanes at 43%. All of it is subject to lender guidelines and full file review, and none of it is a commitment to lend. Lendmire’s jumbo loan programs page lays out the lane structure.
Jumbo loans are not bought by the federal housing agencies. Each lender sets its own overlays. When this article cites agency rules, they show how the industry handles the sell-then-buy problem. A jumbo lender may be stricter or looser.
Key Terms Defined
Anticipated sale proceeds: the estimated cash you will net from selling your current home, before the sale closes.
Bridge loan: short-term borrowing against the current home that lets you close on the new one first.
Home equity line of credit (HELOC): an open-end credit line secured by your home, sized from its value minus what you owe.
Reserves: liquid assets left after closing, measured in months of the full housing payment.
Combined loan-to-value (CLTV): all loans secured by the property, added together, divided by its value.
Contingency: a condition in a sales contract, such as buyer financing, that must clear before the sale is firm.
Why Can’t Sale Proceeds Be Your Down Payment Before Closing?
Because the money does not exist until the old home closes. Lenders treat the stages differently, and the stage your sale has reached drives the whole file.
| Stage of old home | How the lender generally sees it |
|---|---|
| Listed, no contract | Payment counts against you; proceeds are only an estimate |
| Under contract, contingencies open | Payment generally still counts |
| Under contract, contingencies cleared | Payment may drop out of qualifying |
| Closed | Settlement statement proves actual cash |
The conforming guide shows the logic. Under Fannie Mae’s anticipated sales proceeds rule, an unsold home with an agreed price is estimated at the sales price minus sales costs and liens. With no agreed price, the estimate is 90% of the list price minus liens. The lender must also get the old home’s settlement statement before or at the new closing when those proceeds fund the down payment.
So the real number is lower than list price. Realtor costs, payoff, and a price cut all come out first. A jumbo lender may be stricter, so ask what it will accept at each stage.
What Are Your Down Payment Source Options?
Savings, borrowed equity, a bridge loan, gift funds where the lane allows them, and a two-loan structure each solve the cash problem differently. Each also changes qualifying.
| Source | What it funds | Effect on qualifying | Main catch |
|---|---|---|---|
| Savings and investments | Down payment, closing costs | None, but lowers reserves | Drains the cushion |
| HELOC on old home | Down payment | Adds a payment | Payoff at sale |
| Bridge loan | Down payment | Counts as debt | Needs equity |
| Sale proceeds | Down payment | Removes old payment once firm | Only after closing |
| Gift funds | Down payment | No new debt | Lane rules vary |
| Loan plus second lien | Reduces cash down | Two payments | CLTV limits apply |
Savings. Cleanest file, but cash that goes into the down payment is gone from reserves. Funds needed to close are subtracted from your assets before reserves are counted.
HELOC or home equity loan. The CFPB’s HELOC booklet explains that many lenders size the limit from a percentage of appraised value minus the existing mortgage balance. It is a 2014 booklet, so treat that as an illustration. A HELOC is secured by your home, and falling behind can put the home at risk. When you sell, the line generally has to be paid off in full.
Bridge loan. It gets you to the closing table. Under the conforming rules, its payment counts as debt unless you have a signed sale contract and cleared financing contingencies. Whether a jumbo lender offers that exclusion at all is a question for your loan officer.
Gift funds. Some jumbo lanes accept them, with documentation. Many do not, or limit them. Confirm before you build a plan around a gift.
Two-loan structure. A first mortgage plus a second lien lowers the cash you put down. Several of the wholesale lanes reach 89.99% CLTV, and the rest stop at 80%, so the lane you land in decides what this can do.
How Do Lenders Treat the Old Home’s Payment?
By default it counts, and that is usually the hardest part of the file. Two mortgages on a debt ratio can push a buyer past the ceiling, 50% on the fixed lanes, even with plenty of equity.
Under conforming rules, the old payment stops counting only when the file holds a fully executed sales contract and confirmation that financing contingencies are cleared. Fannie Mae’s rule on a current residence pending sale says this. An open financing contingency does not clear the exclusion. A signed contract alone is not enough.
Walk through the three common positions:
- Listed, nothing signed. Expect both payments in the ratio. Strong reserves help, and some lenders want more of them.
- Signed, contingencies open. Treated close to listed-only. The buyer’s lender may still count the old payment.
- Signed, contingencies cleared. The best position. The old payment may drop out, subject to the lane’s guidelines.
If you plan to keep the old home as a rental instead, the rules change. Lenders generally want market rent documented rather than a lease, and may require extra reserves. In short, how the home will be used after you leave decides the treatment. We leave it there.
Down Payment Versus Reserves: Where Files Get Squeezed
A larger down payment can make the file worse. Put in more cash and the loan shrinks, but reserves thin out. On jumbo loans, reserves are measured in months of the full payment and rise with the loan amount. A bigger loan means a bigger reserve requirement in absolute terms. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Picture a buyer with substantial equity in the old home and modest savings. Putting most of the savings down leaves little behind, and the lender may question the file even at a lower loan-to-value. The same buyer may do better putting less down, keeping cash in reserve, and using sale proceeds later to pay the loan down or recast, if the lender allows recasting.
Reserve rules also differ by occupancy. Primary residence, second home, and investment property carry different leverage and reserve expectations on the wholesale lanes. For this article, assume the new home is a primary residence.
Three Buyer Scenarios
High equity, low cash. The buyer owns the old home with a lot of equity but holds little liquid savings. A HELOC or bridge loan turns equity into a down payment. The catch is the added payment on top of the old mortgage, which may push the debt ratio past its ceiling unless the sale is firm.
High cash, thin equity. Savings cover the down payment, but little equity sits in the old home. The old home may net less than expected after costs. Reserves are the risk, so the buyer should size the down payment so that months of reserves remain after closing.
Tight debt ratio. Income is solid but two payments push the ratio near its ceiling. Here the sale stage matters most. A buyer who waits for a signed contract with cleared contingencies may remove the old payment. A lower leverage lane, which avoids the second lien payment, may also help.
What Documents Does the Lender Want?
Plan on a paper trail for every dollar of the down payment.
- Recent statements for the accounts holding savings.
- Listing agreement, and the signed sales contract once there is one.
- Proof that financing contingencies are cleared, if the old payment is to be excluded.
- The old home’s mortgage statement and payoff figure.
- HELOC or bridge loan terms, with the payment included in your ratios.
- A written explanation and paper trail for any large deposit.
- The old home’s settlement statement, delivered before or with the new closing, if sale proceeds fund the purchase.
- Gift letter and donor documentation, if the lane accepts gifts.
Above a lane’s loan threshold, expect two appraisals. The old home may need a valuation too, because a lender sizing a HELOC or bridge advance needs its value and payoff.
What Can Go Wrong, and What Is the Fallback?
The old home may not sell. Then you carry two mortgages, plus any bridge or HELOC payment, and the reserves you counted on start to shrink. Build a plan before you close on the new home: how many months of both payments your reserves can carry, and what price cut you would accept.
Other failure points:
- Closing delays. Proceeds the file depends on arrive late or smaller than estimated.
- Spending reserves into the down payment. The file clears, then leaves no cushion.
- A buyer’s financing contingency falls through on the old home, and the cleared-contingency exclusion disappears.
- HELOC left open after sale. It generally must be paid off, so confirm the payoff at the old home’s settlement.
When Is Buying First the Wrong Move?
When the numbers only work if everything goes right. If the debt ratio fails with the old payment counted, reserves would drop thin, and the old home needs repairs or a price cut, selling first is cleaner. Renting for a short stretch costs less than a stressed file.
Selling first also fits buyers who need proceeds to reach the down payment they want. A contingent offer, where the purchase depends on your sale, is another path, though sellers in a busy market may not accept it.
Frequently Asked Questions
Can I use sale proceeds before the old home closes?
Not as cash. Lenders may count an estimate for qualifying, but the actual proceeds must be documented with a settlement statement at or before the new closing. The estimate is net of costs and liens.
Do I have to sell before I buy a jumbo home?
No. Many buyers close first using savings, a HELOC, or a bridge loan. The tradeoff is carrying two payments, which affects the debt ratio and reserves.
Does a bridge loan count against my debt ratio?
Generally yes. Under conforming rules the payment counts unless the file has a signed sale contract and cleared financing contingencies. A jumbo lender may set a different rule, so ask early.
Does a bigger down payment always help?
No. It lowers the loan amount, but it can drain reserves, and jumbo reserve requirements rise with loan size. The right split balances both. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
How does credit change the picture?
It sets which lane you fit. The headline lane uses a 660 decision score, and higher leverage generally asks more of the file. Lender guidelines and full file review decide the outcome.
