Can You Buy a New Home Before Selling With a Conventional Loan?

The Quick Read: Yes, as long as the numbers work with the old home still on your books. A conventional loan has no rule that says you must sell first. The lender decides how to count the home you still own. A firm, executed sale contract with the buyer’s financing contingencies cleared can take the old payment out of your ratios. Without that contract, both housing payments count against you.

Why the Old Payment Is the Whole Question

The real question is how the lender counts the home you still own. Fannie Mae and Freddie Mac both write their rules around that one point.

Across the wholesale programs Lendmire places files with, the new loan is tested on its own. The leverage limits, the credit floor and the ratio ceiling work the same as for any purchase. Then the old payment gets added or left out, and that decision often moves the file more than anything else.

Under the Fannie Mae default rule, a lender reviews your file on both the current payment and the proposed payment if the current home won’t transfer title before the new loan closes. Each payment includes principal, interest, taxes, insurance and association dues. Fannie Mae makes an exception when the file holds two items: the executed sales contract for the current home, and confirmation that any financing contingencies have been cleared. The rule sits in Fannie Mae Selling Guide B3-6-06.

Freddie Mac takes a similar line. If the current primary residence is pending sale and the sale won’t close before the new loan’s note date, its payment may be left out of the debt-to-income ratio. That requires an executed sales contract in the file. The rule is in Freddie Mac Guide §5401.2. Contract terms matter here, so a lender may ask for more evidence if the sale contract carries a financing contingency.

Everything here stays inside conventional loans. FHA, VA and USDA loans have their own rules.

How Does the Lender Count Your Current Home?

The treatment depends on where the sale stands. Four situations cover most files.

An accepted offer alone is not enough. In the agency text, the executed contract and the status of the buyer’s financing decide the treatment.

If there is no signed contract, you qualify while carrying two housing payments. That is not a denial. It means the new loan has to fit inside your ratios with both payments counted.

How the Ratio Test Works

The test is total debt-to-income, meaning monthly debts divided by gross monthly income. For loans run through the automated system, the wholesale conventional programs use a total ratio ceiling of 50%. Manually underwritten loans sit lower, at 36% or up to 45% with the credit score and reserve factors in the Eligibility Matrix. The ceilings come from Fannie Mae Selling Guide B3-6-02. Freddie Mac’s manual-underwriting limit follows the same pattern, as laid out in its servicing-view Guide section.

Here is the effect with no dollar figures. Say your new payment would take a modest share of income by itself. Add the old payment and the ratio jumps. If the file only clears at the lower number, the old home has to be under a firm contract. If it clears either way, the pending sale is a convenience, not a requirement.

Credit matters too. The wholesale conventional programs start at a 620 decision score, and 640 on an adjustable rate under manual underwriting. The automated finding governs most files. All of it is subject to lender guidelines and full file review.

What Leverage Applies to the New Home?

The new purchase follows normal conventional leverage for the occupancy. On a one-unit principal residence, the program allows 97% LTV (3% down) when at least one borrower is a first-time buyer, meaning no ownership interest in a residence in the previous three years. Most current homeowners don’t fit that definition, so 95% LTV (5% down) is the usual figure. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

Mortgage insurance is required above 80% LTV. You can request cancellation at 80% of the original value, with good payment history, no subordinate liens and no decline in value. The servicer must end it automatically at 78%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

A pending sale doesn’t change the new home’s leverage. Nothing in the agency rules we reviewed says a pending sale changes the appraisal either. The new home is valued on its own.

Where Does the Down Payment Come From?

Sale proceeds don’t exist yet at the purchase closing. That is the second hurdle after the ratios, and it has several answers.

Bridge or swing loan. Fannie Mae allows bridge loan funds to close on a new principal residence before the current home sells. The bridge is a contingent liability counted in monthly debt. Fannie Mae waives that treatment when the file has the executed contract and cleared contingencies. Details are in Fannie Mae Selling Guide B3-6-05. Freddie Mac treats a bridge payment on a home pending sale the same way.

HELOC on the old home. HELOC payments count in recurring debt when there is an outstanding balance. The CFPB’s HELOC page warns that falling behind on a HELOC can put your home at risk. Selling the home generally means paying the line off in full.

Cash-out refinance of the old home. This raises cash before you buy, but the old home carries a new balance and a new payment. Lenders count that payment unless the exclusion applies. Cash-out rules have seasoning of their own, so check them before planning around this path.

Don’t draw a HELOC or take a bridge loan between approval and closing without telling the loan officer. New debt changes the ratios. The loan has to be re-tested.

What Does the Lender Ask For?

Clean paper is what moves an exclusion from “maybe” to “done.” For an old home under contract, the file typically needs:

• The fully executed purchase contract for the old home.
• Proof that the buyer’s financing contingencies are cleared.
• Evidence that the old home’s sale won’t close before your new note date.
• Current mortgage statements on the old home.
• Source documentation for the down payment and any reserves.

Documents used to exclude a liability must meet the agency’s age-of-documentation rules. A stale contract or an old contingency letter can sink the exclusion.

Disclose the old home on the application. Freddie Mac requires liabilities on the application and counts all debts incurred through the note date. Any debt you are obligated to pay on that date counts. Undisclosed mortgage debt, including HELOCs and second liens, is a bad thing to have surface late.

Reserves are a smaller issue than people expect. Fannie Mae sets no minimum reserve requirement for one-unit principal residence purchases, though the automated system can still ask for more based on overall risk. The extra reserves tied to other financed properties exclude your principal residence and any property that is sold or pending sale. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

What Happens If the Sale Falls Apart?

This is where the plan breaks. The exclusion depends on a contract that can still die. If the buyer’s financing falls through before closing, the old payment goes back into your ratios, and the new loan may no longer fit.

Late changes to debt cause the same trouble. A manually underwritten file over 45% is not eligible for delivery, and an automated file over 50% is not either. If your approval was close and a new debt appears, the file can fail at the last test.

Stress-test the plan before you sign. Ask what happens if the old home sits unsold for several months. Can you carry both payments, the taxes and the upkeep on both homes? Are your reserves enough to absorb the gap? Costs run on both properties at once: commissions, bridge fees, interest and utilities while the old home sits. Treat the exclusion as an underwriting treatment only. The old payment is still real money until the sale closes.

An excluded payment also still counts toward the number of financed properties. Fannie Mae places no limit for principal-residence purchases, with HomeReady the exception at two financed properties. That rule is in B2-2-03.

Keeping the Old Home Instead of Selling It

Some borrowers decide to keep the old home as a rental. That is a different path, a “departing residence,” and it changes the file.

Fannie Mae allows a principal residence that will be vacated to be eligible, but the lender must document a current housing payment to use any rental income from it. Lease agreements are not permitted for a departing residence. The lender uses market rent documentation, such as an appraisal rent schedule. Fannie Mae reorganized these rental income topics in its SEL-2026-08 announcement, so confirm the current effective terms with your loan officer before relying on any rental offset.

Occupancy is the other line to watch. The uniform security instrument requires you to move into the new home within 60 days of signing, per Freddie Mac Guide §8405.1. Plan the move around it. A file built on a stated intent to occupy the new home, with no real plan to live there, is the kind of fact pattern agency fraud guidance describes.

Buy First or Sell First?

Neither order is right for everyone. The choice depends on your cash, your ratios and your tolerance for carrying two homes.

Buying first fits borrowers with strong income and cash cushion, or those who already have a firm contract. Selling first fits borrowers whose ratios only work with the old payment gone, or who need the proceeds for the down payment. A middle path is to list the home, wait until an offer is firm and the contingencies clear, then take the purchase to underwriting.

Common Mistakes

1. Assuming you must sell first. No such conventional rule exists.

2. Treating an accepted offer as enough. The exclusion needs the executed contract and cleared contingencies.

3. Counting a lease. A signed lease on the departing home can’t be used under Fannie Mae’s rule.

4. Ignoring the HELOC. Its payment counts, and it must be paid off on sale.

5. Taking new debt before closing. It forces a re-test of the ratios.

6. Reading “excluded” as “paid.” Excluded from the ratio is not the same as paid off.

7. Missing the 60-day move-in window.
