How to assume a mortgage in 2027: step-by-step process, costs, and lender requirements
Mortgage assumption lets a buyer take over the seller's existing loan — including its original interest rate. With many sellers holding 3–4% mortgages, assumptions are the most talked-about strategy in 2027's high-rate market. This guide covers eligibility, the full process, timeline, lender approval, and the gap-financing problem.
Assuming a seller's 3.25% FHA mortgage when new loans are priced at 6.75% saves roughly $700–$1,200 per month on a $300,000 balance. That premium is driving a surge in assumption requests — but the process is slow, lender-dependent, and has a significant gap-financing problem most buyers underestimate.

Step-by-step: how to assume a mortgage
- 1Find a property with an assumable FHA, VA, or USDA mortgage
Work with an agent to identify listings with low-rate government loans. Public records in many counties show loan origination date and lender — cross-reference with 2019–2022 origination dates for the best rate vintage.
- 2Confirm assumption is permitted and calculate the equity gap
Ask the seller's servicer whether the specific loan allows assumption. Verify: current balance, remaining term, and rate. Calculate the gap (purchase price − loan balance) — this is what you must cover in cash or secondary financing.
- 3Apply with the servicer's assumption department
Submit your credit, income, and asset documentation directly to the loan servicer (not a new lender). The servicer underwrites you against the same standards as new origination. Use the CFPB mortgage application checklist for what to prepare.
- 4Arrange gap financing
Options for the equity gap: personal savings, home equity loan from a separate lender (uncommon on assumptions), seller financing (seller holds a second mortgage), or a bridge loan. The gap must be funded at closing — it cannot be included in the assumed loan.
- 5Close and record the assumption
At closing, the title transfers to you, the assumed mortgage is recorded in your name, and the seller is released from the obligation (request formal release of liability in writing). Pay assumption fees and standard closing costs — total typically $2,500–$5,000.

Common questions
What mortgages are assumable in 2027?
Three loan types are assumable by law: FHA loans, VA loans, and USDA loans. Conventional loans are generally not assumable — they include a due-on-sale clause requiring full payoff when the property transfers. The HUD FHA assumption guidelines and VA assumption rules both require lender approval and credit qualification. The key draw: if the seller's FHA or VA loan carries a 3.0–3.5% rate from 2020–2021, assuming it saves thousands per year vs a new loan at 6.5–7%.
What is the gap-financing problem in mortgage assumptions?
The most common obstacle: the assumable loan balance is typically much lower than the purchase price — especially when prices have appreciated. Example: seller bought in 2020 at $350,000 with a 3.25% FHA loan; current balance is $310,000; home now sells for $550,000. You must cover the $240,000 gap between the assumed loan and the purchase price with cash or a second loan. Second mortgages on assumed FHA loans are allowed but rare — most lenders do not offer them. You cannot get a new first mortgage on a property with an assumed loan. This means assumptions work best when the buyer has substantial equity or cash.
How long does a mortgage assumption take?
FHA assumptions typically take 45–90 days to close — significantly longer than a standard purchase. VA assumptions can take 60–120 days. The timeline is driven by the servicer's assumption department, which is separate from origination and often slower. Some servicers have improved processing with dedicated portals. Budget at least 90 days when writing an assumption offer, and build that timeline into your purchase contract. Resources: HUD FHA assumption process and the VA loan assumption page.
Does a VA loan assumption release the veteran seller from liability?
Not automatically. If a VA loan is assumed by a non-veteran buyer without a formal release of liability, the original veteran borrower remains on the hook if the assuming buyer defaults — and the veteran's VA entitlement remains tied up. To avoid this, the selling veteran must request a formal release of liability and substitution of entitlement from the VA lender. This requires the assuming buyer to have sufficient VA entitlement (if a veteran) or to get lender approval for a non-veteran assumption with a concurrent release. Always confirm this step with the VA servicer before accepting an assumption offer. See VA.gov loan assumption guidelines.
What fees are involved in a mortgage assumption?
Assumption fees are regulated by loan type: FHA assumption fee: capped at $900 (processing) + up to $500 in credit/legal fees; VA assumption fee: capped at 0.5% of the loan balance (maximum $300 for non-supervised lenders); USDA assumption fees: vary but are regulated. You also pay standard closing costs: title search, title insurance, recording fees, and potentially a gap-financing origination fee. Total assumption transaction cost: typically $2,500–$5,000 vs $8,000–15,000 for a new loan origination. The CFPB Closing Disclosure itemizes all fees.
Can I assume a mortgage if my credit is below 620?
FHA assumptions require the assuming buyer to meet FHA's credit requirements: minimum 580 credit score for maximum financing, 500–579 with higher down payment. VA assumptions require the lender to determine creditworthiness — no fixed minimum, but most VA servicers apply similar standards to origination. If your credit is below these thresholds, you are not eligible to assume — but you can work on building credit for a mortgage first. Also note: the lender approves the assumption, not HUD directly, so some lenders apply overlays above minimums.
