Can You Buy a New Home Before Selling Your Current One, and What Loan Options Help If You Plan to Sell Within a Year?
Yes. The catch is that the lender will usually count your current home's full monthly payment in your debt-to-income ratio until it sells. There's a way around that: a signed sales contract on the old home with the buyer's financing contingencies cleared. If you might sell or refinance the new loan within a year, check its prepayment terms before you sign.
Last updated September 29, 2026How does your current mortgage count when you buy before selling?
While you still own the old home, standard underwriting adds its whole housing payment to your monthly debts: principal, interest, taxes, insurance and any HOA dues. It stays in the math until the sale closes and title transfers. In effect you're qualified as if you'll carry two house payments, even if you expect a quick sale.
Can you leave the old payment out of your debt ratio?
Yes, with the right paperwork. Under Fannie Mae's guidelines, the lender doesn't have to count the old home's payment if you have a fully signed sales contract on it and the buyer's financing contingencies are cleared. It turns on those documents, not on a set number of days until closing.
If the old home is paid off, the math is easier. Only its property taxes, homeowners insurance and any HOA dues count, since there's no mortgage payment to add.
What should you check if you plan to sell or refinance within a year?
Look for a prepayment penalty. Federal rules limit when a lender can charge one and cap it where it's allowed: no more than 2% of the balance in the first two years, 1% in the third year and nothing after that. If the loan has no penalty, paying it off early costs you nothing extra.
It depends on your situation:
- The old home has a mortgage and no signed sale: its full payment counts in your debt-to-income ratio.
- The old home is under a signed contract with financing contingencies cleared: the lender can leave its payment out.
- The old home is paid off: only taxes, insurance and HOA dues count.
| Old home has a mortgage, no signed sale | Full payment: principal, interest, taxes, insurance, HOA |
|---|---|
| Old home under contract, financing contingencies cleared | Payment can be left out |
| Old home paid off | Taxes, insurance and HOA only |
| Prepayment penalty, where allowed | Up to 2% in years one and two, 1% in year three, none after |
