Moving house when you have a mortgage means selling your current home, using the proceeds to pay off that loan in full at closing, and financing your next home with a new mortgage. Nearly every conventional loan in the United States carries a due-on-sale clause, so you can’t take your existing mortgage with you to a different property. The real work is timing the two transactions, protecting your deposit on the new purchase, and making sure the numbers on your old home actually clear the payoff.
Why Your Current Mortgage Can’t Follow You
Portable mortgages, which let a homeowner carry an interest rate to a new property, do not exist in the U.S. market. Federal law lets lenders enforce due-on-sale clauses, which require the entire loan balance to be repaid when the property is sold or transferred.1Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions Virtually all conventional mortgages include this clause, so your lender gets paid off the day the sale closes.
Loans backed by the FHA, VA, and USDA are assumable, but that helps a qualified buyer take over your loan on the home you’re leaving.2U.S. Department of Housing and Urban Development. Are FHA-Insured Mortgages Assumable? It does nothing for the mortgage you’ll need on the next house. Plan on paying off the existing loan and starting a new one.
Paying Off the Old Loan at Closing
Once you accept an offer, request a payoff statement from your loan servicer. It shows the exact amount to close out the loan on a target date, including remaining principal, interest accrued through that date, and any administrative fees. The figure changes daily as interest accumulates, so it’s tied to a specific closing date rather than the balance on your monthly statement.
At closing, the settlement agent collects the buyer’s funds and distributes them per the contract. Your lender is paid first, then real estate commissions, transfer taxes, and other agreed costs come out of the proceeds.3Consumer Financial Protection Bureau. What Can I Expect in the Mortgage Closing Process? Whatever remains is your equity, and that is what typically funds the down payment on the next home.
Check for a Prepayment Penalty
Most mortgages originated after January 2014 either carry no prepayment penalty or are tightly limited. Under Regulation Z, a prepayment penalty on a qualified mortgage can only apply during the first three years, capped at 2% of the outstanding balance in years one and two and 1% in year three.4eCFR. 12 CFR 1026.43 – Minimum Standards for Transactions Secured by a Dwelling Higher-priced mortgage loans cannot carry prepayment penalties at all. Older or non-qualified loans can, so pull out your promissory note and check the penalty language before you list.
Handling the Gap Between the Two Homes
The hardest part of moving with a mortgage is timing. Sell first and you have clean financing but may need somewhere to live for a stretch. Buy first and you risk carrying two mortgages until the old house sells. Neither is painless; the right pick depends on your local market and your cash cushion.
Selling First
Selling first puts cash in your hand for the down payment and removes the risk of double payments. The tradeoff is interim housing. Some sellers negotiate a rent-back with the buyer, staying in the home for a few weeks after closing in exchange for daily rent. Others go into short-term rentals. This works best when homes in your price range stay on the market long enough that you can locate and close on a new place without scrambling.
Buying First With a Bridge Loan or HELOC
If you buy before the old home sells, you need a way to fund the down payment without your sale proceeds. A bridge loan is a short-term loan, typically 12 to 18 months, secured by your current home’s equity. Rates on residential bridge loans run well above standard mortgage rates, and most lenders cap borrowing at around 70% of the home’s current value minus the existing mortgage balance. You repay it when the old house sells.
A home equity line of credit is cheaper if you set it up in advance. HELOCs let you borrow up to roughly 85% of the home’s value minus what you owe, at a lower rate than a bridge loan. The catch: lenders won’t approve a HELOC on a property that’s actively for sale, so you have to open it before listing. Either way, running two housing obligations at once puts real pressure on your monthly budget, so work the numbers honestly before you commit.
Contract Protections on the New Purchase
When you’re buying while waiting on your own sale or a loan approval, the contingency clauses in your purchase contract are what stop a bad break from costing you your deposit.
Mortgage Contingency
A mortgage contingency, sometimes called a financing contingency, lets you back out and recover your earnest money if the loan falls through. The clause sets a deadline, usually 30 to 45 days, by which you must secure loan approval. Miss that date and you notify the seller and walk with your deposit intact. Without this clause, a denied application could cost you the deposit and expose you to a lawsuit from the seller.
Home Sale and Settlement Contingencies
A home sale contingency makes your purchase conditional on selling your current home first. It shields you from owning two properties at once, but sellers in competitive markets often reject offers that carry one because of the uncertainty. A settlement contingency is a lighter version: it applies when your current home is already under contract, and the new purchase depends on that sale closing. Sellers are more receptive since a committed buyer is already in place.
Qualifying for the New Mortgage
Underwriting on the new loan will ask for a thick stack of paperwork. Having it ready before you apply saves weeks.
- The last two years of W-2 forms and at least 30 days of recent pay stubs. Self-employed borrowers usually need two years of personal and business tax returns instead.
- Two to three months of bank statements for every account you plan to use for the down payment or closing costs. Lenders look for the source of large deposits, so unexplained transfers trigger follow-up questions.
- A list of recurring debts including car loans, student loans, and credit card balances. The lender pulls credit independently, and discrepancies slow things down.
- Government-issued photo ID and your Social Security number for the credit check.
- A signed copy of the purchase agreement for the home you’re buying, including price and contingencies.
Credit Score and Debt-to-Income
For a conventional loan backed by Fannie Mae, the minimum credit score is 620 when the application goes through automated underwriting.5Fannie Mae. Eligibility Matrix FHA loans go as low as 580 with a 3.5% down payment. Higher scores get better rates, so clearing the minimum doesn’t mean you’ll get favorable terms.
The federal qualified mortgage rule no longer sets a hard debt-to-income cap. The CFPB replaced the old 43% DTI limit with a price-based test comparing the loan’s APR to the average prime offer rate.6Consumer Financial Protection Bureau. Qualified Mortgage Definition Under the Truth in Lending Act (Regulation Z): General QM Loan Definition In practice, most lenders still work to a 43% to 50% internal guideline. Keeping total monthly debts, including the projected new mortgage, under 43% of gross income puts you in a strong spot.
Appraisal, Disclosure, and Closing Day
From accepted offer to closing, a conventional loan typically runs about 42 days, or roughly six weeks. Two milestones inside that window matter most.
Your lender orders a professional appraisal to confirm the market value supports the loan amount. A standard single-family appraisal runs roughly $300 to $500. If it comes in below the purchase price, you’ll need to renegotiate with the seller, cover the gap in cash, or walk away. A home inspection is separate and technically optional, though skipping it is one of the more expensive gambles in real estate. Inspections for a typical home run $250 to $425 and cover structure, roof, electrical, plumbing, and HVAC. Significant findings give you room to negotiate repairs, request a price cut, or invoke your inspection contingency.
Federal law requires the lender to deliver a Closing Disclosure at least three business days before you sign. Compare it line by line against the Loan Estimate you got when you applied and ask the loan officer about anything that shifted. Certain last-minute changes restart the three-day clock: an APR increase beyond the accuracy threshold, a new prepayment penalty, or a change in loan product all require a corrected disclosure and another three business days.7Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs Make sure your rate lock has enough runway to absorb a reset.
At closing, the settlement agent coordinates funds between you, your lender, and the seller. The lender wires the loan proceeds to the settlement agent, who combines them with your down payment and distributes the money to the seller and to service providers.3Consumer Financial Protection Bureau. What Can I Expect in the Mortgage Closing Process? Total buyer closing costs generally run 2% to 5% of the purchase price, covering title insurance, prepaid property taxes, recording fees, and the like. Once you sign, the paperwork goes to the county recorder and you get the keys.
If You Owe More Than the Home Is Worth
If your loan balance is higher than the home’s current market value, a standard sale won’t cover the payoff. You have two main options.
The first is bringing cash to closing to cover the shortfall between the sale price and the payoff figure. If you’re only a few thousand dollars underwater, this is usually the simplest way through.
The second is a short sale, where you sell for less than you owe and your lender agrees to accept the reduced amount as full satisfaction of the debt. Short sales require lender approval and take longer than a standard transaction because the lender has to review and accept the offer. Not every lender agrees, and you may need to document financial hardship. Forgiven debt can create a tax liability if the IRS treats the difference as taxable income, and a short sale hits your credit score hard, though less severely than a foreclosure. If waiting for values to recover or bringing cash to the table is an option, it usually beats a short sale.
Tax on the Sale of Your Old Home
Selling at a profit can trigger capital gains tax, but most homeowners exclude a large share of the gain. Single filers can exclude up to $250,000 in profit, and married couples filing jointly up to $500,000, if they meet the ownership and use test.8Internal Revenue Service. Publication 523, Selling Your Home The test requires that you owned and lived in the home as your primary residence for at least two of the five years before the sale.9Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
If you fall short of the full two years because of a job relocation, health issue, or other unforeseen circumstance, you can claim a partial exclusion, prorated by the time you actually lived there.9Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Someone who lived in the home for 12 months before a qualifying job transfer, for example, gets half the normal exclusion. Keep records of your original purchase price, the closing costs from when you bought, and the cost of any major improvements. Those figures reduce your taxable gain if you ever have to calculate it.
