Can I transfer or assume a mortgage when I buy another home?
Understand the difference between taking a mortgage to a different property and allowing a qualified buyer to assume an existing loan, including lender approval, equity, fees, and release of liability.
A U.S. mortgage normally remains secured by the property named in its documents, so you generally cannot move that loan to a different home. A separate option is assumption: an eligible buyer may take over an assumable mortgage on the existing property, usually after the servicer reviews the buyer and completes a written agreement. Most loans do not allow assumptions, while FHA-insured loans are assumable subject to program restrictions and credit review for many newer loans. Check the Assumption section of your Loan Estimate or Closing Disclosure and obtain the servicer's written process and a formal release of your liability before relying on an assumption.
Two ideas are often mixed together. Porting would move your existing debt from the old property to a new property. Assumption keeps the debt attached to the same property but substitutes an approved buyer. Standard U.S. mortgage documents generally do not give a borrower a routine right to port the loan to another home. An assumption is possible only when the loan documents, program, and servicer allow it.
Three different transactions
| Transaction | What happens to the old mortgage | Main approval question |
|---|---|---|
| Sell and get a new mortgage | Sale proceeds pay the old loan; you apply separately for the new home | Do you qualify for and accept the new loan terms? |
| Buyer assumes the old mortgage | Approved buyer takes the loan on the existing property under a written assumption | Is the loan assumable, does the buyer qualify, and are you released? |
| Transfer title without approved assumption | Mortgage remains unresolved and a due-on-sale clause may be triggered | What do the note, security instrument, servicer, and law permit? |
Find the assumption language first
Documents to review
- Closing Disclosure
Check the Assumption field under additional loan information; it states whether a buyer may be allowed to take over the loan.
- Loan Estimate
Review the assumption disclosure and compare it with final documents.
- Promissory note
Read repayment, transfer, and prepayment terms.
- Mortgage or deed of trust
Look for the due-on-sale or transfer clause and permitted exceptions.
- Servicer instructions
Request the current assumption packet, fees, timeline, qualification standard, and release-of-liability form.
Model the equity gap
An assumable balance may be much smaller than the sale price. If a home sells for $425,000 and the assumable loan balance is $260,000, the buyer must cover the $165,000 difference through cash or permitted secondary financing, plus closing costs. A favorable interest rate does not solve that equity requirement.
Protect the seller from continuing liability
Before treating an assumption as complete
- Get written eligibility from the servicer
Do not rely on a listing description or verbal statement that a loan is assumable.
- Require formal buyer approval
The servicer may evaluate income, assets, credit, occupancy, and program-specific eligibility.
- Confirm funds for the equity difference
Coordinate the buyer's cash or allowed secondary loan with the title or closing professional.
- Read the final assumption agreement
Confirm the balance, rate, payment, escrow, fees, effective date, and who will service the loan.
- Obtain a release of liability
Ask for the lender or servicer's formal document releasing the seller; a deed transfer by itself does not prove the debt was removed from the seller.
SUMMARY
The bottom line
You normally pay off the old mortgage and obtain a separate loan for the new property. If a buyer may assume the old loan, verify the disclosure and program, price the equity gap and fees, require servicer approval, and do not close without resolving your liability.
Common questions
Before you move on
Can I move my current mortgage rate to a new house?+
Usually not. The mortgage is secured by the existing property, and most U.S. borrowers pay it off at sale and apply for a new loan. Ask your lender if a rare product-specific feature says otherwise.
Are FHA loans assumable?+
FHA-insured mortgages are assumable, but restrictions apply. Many newer loans require the assuming buyer to pass a creditworthiness review and complete the lender's process.
Does an assumption automatically release the seller?+
Do not assume so. Ask the lender or servicer for the formal release-of-liability document and confirm it is part of closing.
Why might an assumption fail even with a low rate?+
The buyer may not qualify, the loan may not permit assumption, the equity gap may be too large, secondary financing may not work, or the parties may not meet the servicer's timing and document requirements.
