The Quick Read: A conventional purchase can close before your old home sells, but the underwriter counts both housing payments unless the file proves the sale is locked in. That proof is an executed sales contract with the buyer’s financing conditions cleared. Without it, the old payment sits in your debt-to-income ratio (the share of gross monthly income that goes to debt) next to the new one. The rest of this guide shows how to meet that test, or plan around it.
Key Takeaways
- Listing your home does nothing for qualification. A signed contract with cleared contingencies does.
- A home under contract with the buyer’s financing still open gets no relief.
- A HELOC or bridge loan can supply cash, but each adds its own debt to the file.
- Arrange equity access before you list. Lenders can be reluctant once a home is on the market.
- Standard rules, mortgage insurance and credit floors are the same as for any other conventional purchase.
Why Closing First Is Harder Than It Sounds
Most move-up buyers want the same thing. They want to buy the next home without a sale contingency on the offer and without living in a rental in between. Sellers like that kind of offer. Underwriters like it less, because you would own two homes at once.
Conventional payment estimate
The starting figures are an example price at the first-time buyer’s minimum down payment. 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 conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $350,000 price, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, 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 conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
The lender asks one question: can you carry both payments? If the old home has not changed hands by the day the new loan closes, the old payment is still yours. The underwriter adds it to the new payment and measures the total against your income.
A broker sees this problem on file after file. The buyer has plenty of equity and a good income. The sticking point is paper: a contract that has a condition still open, or no contract at all.
Lendmire’s conventional loan programs page covers the loan type in general. This guide covers the narrower question of buying before you sell.
Key Terms Defined
Move-up buyer: a homeowner who buys a larger or better home and plans to sell the current one.
PITIA: principal, interest, taxes, insurance and association dues, the full monthly cost of owning a home.
Pending sale: your current home is under contract but the title has not yet moved to the new owner.
Financing contingency: a clause that lets your buyer back out if their loan falls through. “Cleared” means that clause has been satisfied or removed.
Departing residence: the home you are leaving, whether you sell it or keep it.
Debt-to-income ratio (DTI): your monthly debts divided by your gross monthly income. The new housing payment is part of it.
Reserves: money left in verified accounts after closing, which some files must show.
The Program Envelope
Buying before you sell does not change the loan’s basic limits. Across the wholesale programs a broker places conventional files with, a principal residence purchase generally allows 95% loan-to-value, which means 5% down. The 97% option is for first-time buyers only, meaning no ownership interest in a residence in the previous three years. A move-up buyer owns a home today, so plan on 95%.
Mortgage insurance applies above 80% loan-to-value. You can request cancellation at 80% of the original value, with a good payment history, no second liens and no drop in value. The servicer must end it automatically at 78%.
Wholesale programs generally start at a 620 decision score. The automated underwriting finding governs most files, with a total ratio ceiling of 50%. All of this is subject to lender guidelines and full file review.
Occupancy matters if you plan to keep the old home. Second homes top out at 90% leverage, and investment property sits lower still, so the old home’s use changes what the lender allows. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
How Does an Underwriter Treat Two Homes?
The underwriter treats the old payment as a real debt until the file shows it will disappear. Under Fannie Mae’s Selling Guide on other real estate owned, a borrower whose home is pending sale, but whose title will not transfer before the new loan closes, is qualified with both PITIAs. The old payment can be left out only if the file holds two things: the executed sales contract and confirmation that any financing contingencies are cleared.
Freddie Mac’s version is close but not identical. Its Seller/Servicer Guide section 5401.2 says the payment on the property pending sale may be excluded when the file has an executed contract. If the contract carries a financing contingency, the file must show it is cleared. Alternatively, it can show a lender’s commitment to the buyer of the home being sold.
Two details matter here. Freddie’s wording is “may be excluded,” so the exclusion is conditional. And the two agencies differ in the details, so the lender applies whichever guide governs your loan.
The Three States of Your Old Home
| Old home status | Old payment counted? | What the file needs |
|---|---|---|
| Listed, no contract | Yes | Nothing helps yet |
| Contract, financing open | Yes | Clearance, or Freddie’s lender commitment |
| Contract, contingencies cleared | May be excluded | Executed contract plus proof |
The test is whether title transfers before the new loan closes. Being listed or being under contract is not the same thing.
The Step-by-Step Underwriting Path
1. Inventory every housing payment. The underwriter lists the old PITIA, any second mortgage or HELOC on the old home, and the new PITIA.
2. Run the default test. Both payments count unless the exclusion conditions are met.
3. Check the exclusion documents. The file needs the executed contract and any addenda. It also needs proof that financing contingencies are removed, or a commitment letter where the program allows.
4. Settle cash to close. Funds for the down payment, closing costs and reserves must come from verified sources. Borrowing against an asset, such as equity in the old home, is generally acceptable. The lender confirms the funds actually reached you.
5. Look at reserves. The automated underwriting finding sets the requirement for each file. Owning two properties tends to draw more attention to your cash after closing.
6. Apply the appraisal and the overlays. The new home’s appraisal follows ordinary purchase rules. Nothing special attaches to it because your old home is pending. The lender’s own overlays can still be stricter than the agencies.
What decides the outcome comes down to four things: whether DTI passes with both payments, whether the exclusion documents are complete, the automated recommendation, and the lender’s overlays. A financing contingency that has not cleared is the usual sticking point.
A Hypothetical Worked Example
These figures are made up to show the mechanics. They are not typical of any market.
Say your gross monthly income is the base for every percentage below, and other debts are small.
- New housing payment: 28% of gross monthly income.
- Old housing payment: 17% of gross monthly income.
- Other monthly debts: 6% of gross monthly income.
- DTI counting both homes: 51%.
- DTI with the old payment excluded: 34%.
With both payments counted, the total lands above the 50% ceiling that most automated files use. With the exclusion documented, the same buyer sits comfortably below it. The income, the new home and the old mortgage did not change. Only the paperwork did.
That is why a financing contingency still open on your sale can sink an otherwise strong file.
Funding the Gap
The down payment on the new home often comes from the equity in the old one. If the old home has not sold, you need a bridge. Here are the common choices.
| Option | What it gives you | What it adds to the file |
|---|---|---|
| Savings | Cash with no new debt | Lower reserves after closing |
| HELOC on old home | Borrowed equity | A monthly debt payment |
| Bridge loan | Short-term equity funds | A contingent liability in DTI |
| Sale contingency | No bridge needed | A weaker offer to the seller |
A HELOC does not fix DTI by itself. It supplies cash but adds a monthly obligation, and Fannie Mae treats its payment as debt. The same guide treats a bridge or swing loan as a contingent liability that counts in DTI.
Freddie Mac lists a bridge loan payment among the expenses that go into DTI.
Bridge loan costs run higher than standard mortgage costs. Plan on that qualitatively and get the actual terms in writing before you commit.
A Caution on HELOC Timing
A HELOC is revolving credit secured by your home. The CFPB says to consider one only if you are confident you can keep up with the payments, because falling behind could cost you the home. Lenders may also freeze or reduce a line if values fall. When you sell, you are generally expected to pay the line off.
The practical point is timing. Many lenders are reluctant to open a new line on a home that is already listed. Open equity access before you list. Lendmire’s piece How Much Sale Equity a Move-Up Buyer Needs on a Conventional Loan goes deeper on sizing it.
Sell First, Buy First, or Close Together?
| Sequence | Qualification impact | Main risk |
|---|---|---|
| Sell first | Cleanest, one payment | Temporary housing |
| Buy first | Both payments unless excluded | Carrying two homes |
| Close together | Sale proceeds fund the buy | One delay breaks both |
Closing together looks tidy, but the new loan has to close after the old title transfers, or the file needs the exclusion paperwork. Many buyers end up in the middle: a contract on the old home with a cleared contingency, then a purchase on the new one.
The real decision is a timing structure, not a loan product. You choose how much risk of overlap you can tolerate.
Where the General Rule Breaks
Contract with financing still open. No exclusion under either guide until the contingency is cleared. Freddie’s lender-commitment alternative is the only other route.
Relocation. Freddie has a separate carve-out. The pending-sale payment may be excluded for borrowers relocated under an employee relocation program.
Assumed mortgage. If your buyer assumes your old mortgage without releasing you, Fannie requires counting it unless you have a documented history of timely payments.
Keeping the old home. Rental income from a departing residence is treated by its own rules. Per Fannie Mae’s Quality Insider, without a documented history of rental income or property-management experience, that income can only offset housing expense. With the history, it can count as income. Older advice about a fixed equity requirement for converting a home to rental has been dropped, so do not rely on it.
Occupancy. A second home must be one unit, occupied for part of the year and under your control. That decides whether a plan to keep the old house qualifies as a second home or falls into a different category with lower leverage.
Lender overlays. A lender can be stricter than the agencies. Two lenders reading the same guide can reach different answers.
Timeline Walkthrough
Here is the order of events that tends to work. Dates matter less than overlap points.
1. Before listing: Get preapproved with both payments counted. Set up any HELOC while the home is unlisted.
2. List and receive an offer: The executed contract is the first exclusion document.
3. Negotiate contingencies: The buyer’s financing condition is the one to watch. Ask for it to be cleared as early as the contract allows.
4. Make your offer on the new home: A strong preapproval makes a clean offer credible.
5. Appraisal and underwriting: The lender collects the contract, any addenda and proof of clearance.
6. New loan closes: If title on the old home has not moved, the exclusion documents carry the file.
7. Old sale closes: The old mortgage pays off and the overlap ends.
Step 3 is the pinch point. If the contingency stays open at your new closing, both payments count again.
Documentation Checklist
- The executed sales contract for the old home, with all addenda.
- Proof the financing contingency is cleared, or the buyer’s lender commitment where Freddie’s alternative applies.
- Current statements for the old mortgage and any HELOC.
- Evidence of the funds used for cash to close, with the paper trail from the account they came from.
- Lease or rental history, if you plan to keep the old home.
- Your usual income, asset and credit documents.
Ask your loan officer which agency’s guide governs your loan, since the conditions differ in detail. Ask also whether the lender has overlays on pending-sale files.
What Can Go Wrong, and the Backup Plan
The biggest risk is a contract that collapses before the new loan closes. The exclusion disappears, both payments count again, and the file may no longer fit under the ratio ceiling.
A second risk is a delay in the old sale after your new loan has closed. The new loan was approved on documented conditions, so the issue becomes a cash-flow problem, not an underwriting event. You carry two mortgages, taxes, insurance and utilities, plus any bridge or HELOC interest.
Three buffers help. Keep reserves beyond what the lender requires. Choose a down payment that leaves cash after closing. And know your bridge-out option before you need it.
Which Path Fits You?
| Your situation | Likely path |
|---|---|
| Contract, contingencies cleared | Buy now, old payment may be excluded |
| Contract, financing open | Wait for clearance, or ask about a lender commitment |
| Listed, no contract | Qualify with both payments |
| Strong income margin, equity access | Buy first is realistic |
| Thin income margin | Sell first |
Frequently Asked Questions
Does listing my home change how the lender qualifies me?
No. Listing does not remove the old payment from your DTI. Only an executed sales contract with the financing contingency cleared does that, and Freddie also accepts a lender commitment to the buyer in place of clearance.
Can a HELOC solve the two-payment problem?
Not by itself. It supplies cash for the down payment, which helps, but the HELOC payment counts as monthly debt. The old mortgage payment can only drop out through the exclusion conditions.
Do Fannie Mae and Freddie Mac apply identical rules?
They are similar but not identical. Fannie says it will not require the payment to be counted when its conditions are met, while Freddie says it may be excluded. The wording and the alternate documents differ, so the lender follows whichever guide governs your loan.
Can rent from the old house offset its payment?
Sometimes. With a documented history of rental income or property-management experience, it can count as income. Without that history, it can only offset housing expense.
What if I put 5% down and sell my old home later?
The sale proceeds can pay down the balance. Mortgage insurance can be cancelled on request at 80% of the original value, with a good payment history and no second liens, and ends automatically at 78%. Ask the servicer what it requires for a lump-sum payment. Lendmire’s how much a refinance costs vs pmi for move-up conventional loan buyers walks through the choice.
Next Step
If you are buying a home and want to see whether a conventional loan fits your file, Lendmire can help you compare the options and what each one asks of the file. A good starting point is a preapproval run both ways, with your old payment counted and with it excluded. The gap between those two answers shows how much the paperwork on your sale will matter.
