The Quick Read: Lenders can approve a jumbo purchase before your old home sells, but the old home’s monthly payment is the number that decides how much loan fits. That payment counts against your income unless a signed sale contract removes it or documented rent offsets it. Evidence, cash reserves and each lender’s own rules do the rest. Every point below is subject to lender guidelines and full file review.
Key Takeaways
- A loan is jumbo when it runs above your county’s conforming limit. The loan amount decides it, not the price.
- While you own the old home, its full payment usually sits in your debt ratio next to the new one.
- Three paths change that: a signed sale contract, documented rent, or neither.
- A listing does not count as a sale. Only a contract with cleared contingencies carries weight.
- Reserves and down-payment cash for both homes often decide a file that clears on ratio.
What Makes a Loan Jumbo?
A jumbo loan is any mortgage above the conforming loan limit for the county where the home sits. That limit is a ceiling on the loans that the two big government-backed mortgage buyers will purchase. One dollar above it, and the loan is jumbo.
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.
The limit changes by county and by year, so a single national number does not exist. A home priced well above the limit can still produce a conforming loan if you put enough down. A modest-priced home in an expensive county can do the reverse.
Lendmire’s jumbo loan programs are arranged through wholesale lenders. Across those lanes, the headline program starts at a 660 decision score and reaches 90% leverage. Several lanes reach 89.99% combined loan-to-value (CLTV, which stacks every loan against the home’s value). The rest stop 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. Fixed, adjustable and interest-only structures all exist. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Those ceilings matter here because the old home eats into them. You are not just asking whether you can afford the new place. You are asking whether you can afford it with the old place still on your books.
How Does a Lender Count the Old Home’s Payment?
The lender adds the old home’s full monthly cost to the new jumbo payment, then divides by your gross monthly income. That result is your debt-to-income ratio (DTI). Gross means before taxes.
“Full cost” is broader than the mortgage check. Lenders use PITIA: principal, interest, property taxes, homeowners insurance and any association dues. Skip one piece and the number comes up short.
DTI works like a speed limit. The fixed lanes top out at 50%. Adjustable lanes stop at 45%, and interest-only lanes at 43%. A buyer who sits comfortably under those lines on the new payment alone can land over them once the old payment joins in.
Picture a hypothetical buyer. With only the new payment counted, the ratio sits in the low 40s. Add the old home’s full payment and it climbs past 50%. Same buyer, same income, same house. The only difference is how the old home is treated.
(That swing is why two borrowers with similar paychecks get different answers on the same day.)
Which of Three Paths Is Your Old Home On?
Your old home falls into one of three buckets, and each bucket changes the old payment’s weight. The first is a signed sale contract. The second is a plan to keep the home and rent it. The third is neither, which is the default.
Path A: a signed sale contract that closes after your new loan. Under Fannie Mae’s Selling Guide, if the old home sells but the title does not transfer before your purchase closes, both payments are normally counted. The exception: the old payment can be left out when the executed sales contract is in the file and any financing contingencies are cleared. A contingency is a condition the buyer can use to back out, such as their own loan approval. Open contingencies mean the sale is not firm, so the old payment stays.
Path B: you keep the old home and rent it out. The same guide describes this as a “departing residence,” meaning a primary home you vacate and convert into a rental when you buy the next one. Fannie Mae’s rule on departing residences allows rent to count. The lender must document a current housing payment and keep market-rent support in the file.
Path C: no sale and no rental. The full old payment counts, and the lender may ask for extra reserves. This is the default if A and B do not apply. A home that is merely listed belongs here until a buyer signs.
| Where is your old home? | Old payment counted? | What the lender wants |
|---|---|---|
| Listed, no contract | Yes, in full | Mortgage, tax, insurance records |
| Contract, contingencies open | Yes, in full | Contract plus status updates |
| Contract, contingencies cleared | Often removed | Signed contract, proof of clearance |
| Keeping it as a rental | Offset by some rent | Market-rent support, payment history |
| Keeping it, no rent | Yes, in full | Reserves for the old home |
Those rows reflect the agency approach to conforming loans. Jumbo loans sit outside those rules, which is the next point.
Do Agency Rules Apply to a Jumbo Loan?
Not directly. Fannie Mae and Freddie Mac set their rules for conforming loans. A jumbo loan is underwritten to each investor’s own overlays, which are extra rules layered on top of the basics.
Many jumbo investors borrow the agency logic for the old home. Others ask for more: the full old payment regardless of a contract, extra reserves, or a signed lease. Ask your loan officer which treatment the jumbo investor applies. No neutral source sets one universal jumbo rule, and the answer can differ from lane to lane.
Federal rules require a lender to make a good-faith check that you can repay based on documented information. But the CFPB’s own compliance guide says that rule does not provide comprehensive underwriting standards. So how the old payment is counted comes down to the investor’s guidelines. That is where a broker earns the fee, by matching your situation to the lane that treats it best.
How Does Rent From the Old Home Get Counted?
Rent rarely counts in full. Lenders apply a haircut, then use what is left against the old payment. Under Freddie Mac’s guide, the lender uses 75% of gross monthly lease rent when a lease exists, or market rent from the appraisal when it does not. The other 25% covers vacancy and upkeep.
Then comes the second test. Freddie Mac allows full net rental income only if at least one borrower has a year of experience managing investment property. Without that, the rent is limited to an offset. It can shrink the old payment but cannot be added to your income.
Think of it as a coupon, not a paycheck. If the haircut rent covers the old payment, the old payment drops out of your ratio. If rent falls short, the shortfall goes into your DTI. If rent runs higher than the payment, the extra does not help you qualify.
A few related points:
- Freddie Mac says each borrower using rent must currently own a primary residence or have a documented rental housing payment.
- Fannie Mae’s departing-residence rules have moved toward market-supported rent and away from leases. Check which version your lender applies.
- A lease is no longer the starting point under the agency approach. If a jumbo investor still asks for one, that is its overlay.
- Do not assume projected rent will fix a tight file.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Reserves, Down Payment and Where the Cash Comes From
Reserves are cash you hold after closing, measured in months of the full payment. On jumbo lanes they rise with the loan amount. Bigger loan, more months. If you keep the old home, expect the lender to want reserves for both properties.
The down payment is the second pressure point. Most of your cash may be locked in the old home’s equity. A lender will not treat a listing as proof of funds. You need money you can document.
| Source | What it does | Main risk |
|---|---|---|
| Savings | Simplest to document | Drains reserves |
| Home equity line (HELOC) | Taps old-home equity | Adds a payment; may need payoff on sale |
| Bridge loan | Short-term loan on old home | Extra cost; payoff risk |
| Sale proceeds at closing | Clean, if timing lines up | Only works if sale closes first |
A HELOC is a revolving credit line secured by the old home. Lenders generally want it opened before you list the home, and a sale generally requires paying it off. A bridge loan is a short-term loan that covers the gap between buying and selling. The CFPB guide notes that bridge loans of 12 months or less are excluded from its ability-to-repay requirement. That is a regulatory detail, not a safety net. A bridge loan still adds cost and a payoff deadline, and its payment may count in your DTI.
The old payment stays whether you carry a line, a bridge or neither.
Where the General Rule Breaks
These are the situations that change a file most often.
A sale contract with a financing contingency still open. The old payment counts. Your buyer’s loan approval is not final until the contingency clears.
Occupancy. The new home must be your primary residence for primary-home treatment. The old home turns into a rental only if you rent it. A home you keep and leave empty is not a rental, so no rent can offset it. Occupancy also changes leverage on jumbo lanes, so confirm the new home’s classification early.
Co-borrowers. If rent is part of the plan, each borrower must meet the ownership or documented-payment test described above.
County loan limits. The Federal Housing Finance Agency sets a baseline limit each year. In high-cost counties the limit rises, to as much as 150% of the baseline. So the same loan can be conforming in one county and jumbo in the next. Your county sets the line.
Two appraisals. Above a lane’s threshold amount, the lender orders two appraisals. The new home gets appraised for the loan. If the old home will be rented, the lender may also want a market-rent opinion.
Income that is hard to document. Self-employed borrowers or those with large expenses face a second hurdle on top of the old payment. Lendmire’s piece Can a Trucker Still Qualify for a Home Loan in a High-Expense Year? shows how income gets measured when write-offs shrink it.
A Worked Scenario
Consider a hypothetical buyer putting down 20% on a home well above the county’s conforming limit. Their ratio is comfortable on the new payment alone. Here is how three versions of the same file play out. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Version one: listed, no contract. The old payment counts in full. The ratio lands above 50%. On a fixed lane, that is over the ceiling. The buyer either needs a smaller loan, more income, or a different path.
Version two: signed contract, contingencies cleared. The lender can often leave the old payment out, subject to the investor’s overlays. The ratio drops back into the low 40s. The file now turns on cash to close and reserves.
Version three: keeping the home and renting it. Say 75% of market rent covers most of the old payment. The shortfall, not the full payment, goes into the ratio. The result lands between the first two versions. And the buyer needs reserves for the old home too.
Same buyer, three outcomes. That is why the question “can I qualify” has no answer until someone knows which path you are on.
What Documents Does the Lender Want?
Jumbo investors vary, but a lender typically asks for the following on the old home:
- Current mortgage statement
- Property tax and homeowners insurance records
- Association dues, if any
- Executed sale contract, plus proof that contingencies are cleared
- Market-rent support, such as an appraiser’s rent schedule or a market-analysis report
- Proof of reserves
- Listing agreement, if the home is on the market
For the new purchase, expect the usual pay records, asset statements and identification. Many lenders re-check the old home’s status close to closing. If a contract collapses before then, your file is re-evaluated on the old payment. Bring updates to your loan officer when the sale changes, not after.
What If the Old Home Never Sells?
Then you are carrying two homes, and sometimes three obligations: the new mortgage, the old mortgage and a bridge loan. That is the real risk in buying before selling.
Plan for it before you sign. Ask whether your income and reserves hold up if the old home sits for months. If they only work when the sale closes on schedule, the plan is too thin. Options include renting the old home, pricing it to move, or buying a smaller home. A good loan officer will stress-test the file before you commit to the new contract.
What Should You Ask Any Lender?
Put these questions to every loan officer. The answers show how the investor treats the old home.
1. Is the old payment counted in full if my home is listed but unsold?
2. What do you need to remove it: a contract, cleared contingencies, both?
3. If I rent the old home, how is rent counted, and is a lease required?
4. How many months of reserves does this loan amount need, and are old-home reserves stacked on top?
5. Do you order two appraisals at my loan amount?
6. Which ratio ceiling applies to the structure I want?
A lender that answers plainly is usually one that has done this before.
Key Terms Defined
Jumbo loan: a mortgage above the conforming loan limit for the county where the home sits.
DTI (debt-to-income ratio): your total monthly debt payments divided by your gross monthly income.
PITIA: principal, interest, taxes, insurance and association dues, the full monthly cost of a home.
Reserves: cash left after closing, counted in months of the full payment.
Departing residence: your current primary home when you move out and keep it as a rental.
Contingency: a condition in a sale contract that lets a party back out if it is not met.
CLTV: combined loan-to-value, which adds every loan against the home and divides by its value.
What Should You Do Next?
Start by pinning down your old home’s status: listed, under contract, or staying yours. Then gather the documents above. 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. Qualification is subject to lender guidelines and full file review, and nothing here is a commitment to lend.
Frequently Asked Questions
Can I get a jumbo loan if my old home is listed but not under contract?
Often yes, but the old payment usually counts in full. A listing shows intent, not a buyer. The question becomes whether your income and reserves carry both homes. Your loan officer can check that before you make an offer.
Does a signed sale contract remove the old payment?
It can, but only when the sale is firm. Under the agency approach for conforming loans, the contract must be executed and any financing contingencies cleared. Jumbo investors set their own overlays, so some will still count the payment. Ask before you rely on it.
Can rent from the old home help me qualify?
It can offset the old payment, not add to your income. Lenders apply a haircut, commonly 75% of gross rent in the agency approach. Without a year of landlord experience, rent typically only offsets the payment. Any shortfall goes into your ratio.
Should I use a bridge loan or a home equity line?
It depends on timing and cost. A line is generally easier to open before you list and may need to be paid off at sale. A bridge loan covers a short gap but adds cost and a payoff deadline. Either one may add a payment that counts against you.
How much cash do I need to hold back?
Enough to cover the down payment, closing costs and reserves for the new home. On jumbo lanes, reserves rise with the loan amount. If you keep the old home, expect the lender to want reserves for it as well.
