Are conventional loans assumable? In almost every case, no. Nearly every conventional mortgage written today contains a due-on-sale clause that lets the lender demand the full balance the moment the property changes hands. The narrow exceptions are certain adjustable-rate loans whose notes specifically permit assumption, and a set of family-related transfers that federal law shields from acceleration.
Why the Due-on-Sale Clause Blocks Assumption
A due-on-sale clause is a standard provision in conventional mortgage contracts that gives the lender the right to call the entire remaining balance due if the property is sold or transferred without written consent. Federal law defines it as a contract term authorizing the lender “to declare due and payable sums secured by the lender’s security instrument” when all or part of the property is transferred.1Office of the Law Revision Counsel. 12 USC 1701j-3 Preemption of Due-on-Sale Prohibitions
Lenders include the clause to keep a new buyer from inheriting a below-market interest rate. Because conventional loans are packaged and sold into the secondary market through Fannie Mae and Freddie Mac, the clause is standardized across virtually all non-government-backed mortgages. Transfer the property without permission and the lender can accelerate the loan, meaning the full balance becomes due right away.
When a Conventional Loan Can Actually Be Assumed
Fixed-rate conventional mortgages backed by Fannie Mae or Freddie Mac almost never include assumption provisions. Some adjustable-rate mortgages do, but only while the loan remains in its adjustable phase. If the ARM has been modified or has exited that phase, the servicer will likely deny the request.
When the note permits assumption, the new borrower goes through what amounts to a fresh underwriting. The servicer pulls credit, verifies income and assets, and checks debt-to-income. Conventional underwriting generally calls for a minimum credit score around 620 and a debt-to-income ratio no higher than 43 to 49 percent. Expect the review to take 60 to 90 days.
Family and Estate Transfers Federal Law Protects
The Garn-St. Germain Depository Institutions Act of 1982 bars lenders from accelerating a loan during certain non-arm’s-length transfers on residential property with fewer than five units.1Office of the Law Revision Counsel. 12 USC 1701j-3 Preemption of Due-on-Sale Prohibitions The protected situations most homeowners run into:
- The death of a joint tenant, with the surviving owner inheriting by operation of law.
- Inheritance of the home by a relative after the borrower dies.
- A transfer to the borrower’s spouse or children.
- Transfers under a divorce decree, legal separation agreement, or related property settlement.
- Moving the property into a revocable living trust where the borrower stays a beneficiary and continues to occupy the home.2eCFR. 12 CFR Part 191 – Preemption of State Due-on-Sale Laws
- Granting a lease of three years or less with no option to purchase.
These aren’t traditional assumptions. The new owner steps into the existing mortgage, but the lender doesn’t approve a new borrower or re-underwrite. The loan simply stays in place on its original terms.
The Equity Gap Is the Bigger Problem
Even when a conventional loan is technically assumable, the buyer runs into a financial wall. You can only assume the remaining balance, not the home’s full value. The difference is the equity gap, and the buyer has to cover it.
Say a home is worth $450,000 and the remaining mortgage balance is $250,000. The buyer needs $200,000, paid in cash at closing or through a separate second mortgage. Finding a lender willing to sit behind an assumed first lien adds complexity and cost, and the combined payments can easily wipe out the interest-rate savings that made the assumption attractive in the first place.
Costs and Paperwork If You Qualify
The servicer charges a fee to process an assumption. Under Fannie Mae’s servicing guidelines, the fee is $100 when no credit review is required, or the greater of $400 or one percent of the unpaid principal balance when the servicer must underwrite the new borrower.3Fannie Mae. Fees for Certain Servicing Activities On a $300,000 balance, one percent runs $3,000. On top of that, expect a title search and new title policy, county recording fees, and, in some states, attorney or settlement agent fees.
Before you contact anyone, confirm which investor owns the loan. Fannie Mae and Freddie Mac both offer free online lookup tools. Once you know the investor, the current servicer prepares the assumption documents. The prospective borrower should have recent pay stubs, W-2s (or two years of returns if self-employed), bank statements, and credit authorization ready.
Get the Release of Liability in Writing
If you’re the seller, the closing package needs a formal release of liability from the lender. Without it, you remain personally responsible for the mortgage even after someone else takes over the payments. If the new borrower later defaults, the lender can come after you for the full unpaid balance, and a missed payment years down the road can wreck your credit and trigger collection against you. Insist on the written release.
Once the servicer signs off, the release frees the original borrower, the new borrower signs a modified mortgage or assumption agreement, and the paperwork is recorded with the county.4Fannie Mae.

What Happens to PMI After an Assumption
Private mortgage insurance follows the loan. If the mortgage carried PMI before the assumption, it still does after, and the new borrower can’t ask for termination based on current appraised value until they’ve built a 24-month payment history on the loan.6Fannie Mae. Termination of Conventional Mortgage Insurance Even after that, the borrower needs a clean recent payment record (no 30-day lates in the last 12 months, no 60-day lates in the last 24) and has to meet loan-to-value thresholds: 75 percent or less on a one-unit primary residence or second home if the loan is between two and five years old, 80 percent or less if seasoned beyond five years, and 70 percent or less for investment or multi-unit properties with more than two years of seasoning. PMI removal after an assumption generally takes longer than it would for a borrower who originated a new loan.
Government-Backed Loans Are the Assumable Ones
If assumability is what you’re looking for, government-backed mortgages are a different world. Every FHA loan is assumable; loans originated on or after December 15, 1989 require the new borrower to qualify through the lender, generally with a credit score of at least 580 and a DTI of 43 percent or less. VA loans are assumable by anyone, including non-veterans, as long as the new borrower qualifies with the servicer, and the VA charges a funding fee of 0.5 percent of the loan balance on assumptions.7Veterans Benefits Administration. VA Home Loan Guaranty Buyers Guide USDA Rural Development loans are assumable too, provided the new borrower meets USDA income and property eligibility rules.
Servicer fees on government-backed assumptions are also capped much lower. The VA caps its assumption processing fee at $300 for assumptions handled with automatic authority, or $250 for those requiring VA prior approval.8Veterans Benefits Administration. Circular 26-23-10 – VA Assumption Updates
Don’t Try an Unauthorized Transfer
Transferring a property without telling the lender, sometimes called a quiet assumption, is risky. If the lender finds out, it can invoke the due-on-sale clause and send a notice of acceleration. Standard Fannie Mae and Freddie Mac mortgage documents give the borrower at least 30 days from the notice to pay the full balance. Miss that window and the lender can start foreclosure without further notice.
There’s a title problem too. The original owner’s title policy was issued based on ownership at closing, and an undisclosed transfer can leave the new occupant with gaps in coverage against title defects. Any buyer looking at a home with an existing mortgage should confirm in writing that the loan is genuinely assumable before going any further.
