Should You Assume a Seller's 3.25% FHA Loan, or Take a New One at 7.18%? The Real 5-Year Cost

Correction November 11, 2026: The rate gap between the assumed 3.25% FHA loan and the 7.18% new-loan rate was given as roughly 394 basis points; 7.18% minus 3.25% is 393 basis points. The paragraph on approval risk also stated FHA’s underwriting thresholds as a flat “580 or higher” score and “43% or lower” debt-to-income; HUD publishes the manual-underwriting limits as a grid (31%/43% with no compensating factors, 37%/47% with one, 40%/50% with two), and that passage has been rewritten to match.

A seller's FHA mortgage rarely comes up in a home search, but it should. Assuming an existing FHA loan means taking over the seller's balance, rate, and repayment schedule instead of applying for a new loan. In the worked scenario below, a buyer who assumes a seller's $280,000 FHA loan at 3.25% comes out roughly $49,000 ahead over five years, and about $290 a month ahead, versus a new $280,000 loan at the 7.18% rate Freddie Mac reported as the national average on November 5, 2026. The math only works if the buyer can clear two hurdles a new loan doesn't impose: covering the equity gap in cash or a second loan, and getting a lender to approve the assumption at all.

Key takeaways

• Assuming a seller's $280,000 FHA loan at 3.25%, five years into its term, carries a combined payment (assumed first lien plus a second lien covering the equity gap) of about $1,606.77 a month, versus $1,896.82 a month for a new $280,000 loan at the 7.18% rate Freddie Mac reported as the national average for November 5, 2026.
• Over the next five years, the assumption scenario costs roughly $54,474 in interest and fees combined, against roughly $103,478 for the new-loan scenario — a difference of about $49,005 in favor of assumption, before accounting for mortgage insurance.
• Both FHA's $1,800 cap on servicer assumption-processing fees and the underwriting standard that a buyer must still qualify for the loan (credit score, debt-to-income ratio, owner-occupancy) are confirmed as currently in force for 2026, not legacy figures.
• The entire advantage depends on the buyer being able to fund the equity gap — the difference between the purchase price and the remaining loan balance — without a financing structure that erases the rate savings, and on a lender approving the assumption in the first place.

How FHA loan assumption actually works

An FHA-insured mortgage is one of the few home loans that can legally transfer from a seller to a buyer, keeping the original rate, balance, and repayment schedule intact — something a conventional loan generally cannot do. The process is not automatic and does not bypass underwriting. Per loan-assumption guidance published by Quicken Loans, the lender, not the seller, approves the transfer, and a buyer must clear essentially the same bar as a new FHA borrower.

In broad strokes, the steps a buyer and seller go through are these:

1. The seller confirms the mortgage is assumable and requests lender approval, since the lender — not the seller — decides whether the assumption proceeds.
2. The buyer applies to the servicer for assumption underwriting, which checks credit score, debt-to-income ratio, employment history, and an intent to occupy the home as a primary residence.
3. The buyer and seller agree on how the equity gap — the purchase price minus the remaining loan balance — will be covered, typically cash at closing or a second loan.
4. The servicer processes the transfer, charging an assumption fee of up to $1,800, and the seller requests a release of liability so they are no longer responsible for the loan.

Sellers generally need to have held the loan at least a year and be current on payments. None of this is discouraged by HUD — the agency doubled its assumption-fee cap specifically to speed these transactions along, per a May 2024 National Association of Realtors policy update that remains the governing figure cited in 2026 guidance.

The scenario: a $280,000 FHA loan, five years in

Here is the household situation this analysis runs the numbers on. Five years ago, a seller financed a home with a $280,000 FHA loan at a 3.25% fixed rate on a 30-year term. Monthly principal-and-interest is $1,218.58. After 60 payments, standard amortization leaves a remaining balance of $250,058.92 — roughly $250,000. The seller is now listing the home for $280,000, meaning a buyer who wants to assume the loan rather than finance the full price would need to cover a $29,941.08 equity gap, which this analysis rounds to $30,000 for a clean second-lien structure.

These figures are deliberately plain: a round starting balance, a fixed rate, and a sale price equal to the original loan amount with no appreciation built in. A seller who has owned longer, or in a market with meaningful price appreciation, would show a wider equity gap and a smaller remaining balance — both of which change the comparison, sometimes substantially. This is one illustrative case, not a universal result.

Scenario A: assuming the seller's loan

Under assumption, the buyer takes over the $250,058.92 remaining balance at the seller's original 3.25% rate for the 25 years left on the term, keeping the $1,218.58 monthly payment unchanged. The $30,000 equity gap is financed here with a second-lien loan at 9.5% over 10 years, a representative rate for a small, subordinate-position consumer loan in November 2026 — a buyer with cash on hand to cover the gap outright would skip this piece and come out further ahead. That second lien carries its own payment of $388.19 a month, for a combined payment of $1,606.77.

On top of that, the buyer owes FHA's assumption-processing fee, capped at $1,800 per HUD's 2024 policy update, plus closing costs for title work, recording, and the second-lien origination, estimated here at $3,000 — a figure that varies by state and title company and should be confirmed locally. Over the first five years, the first lien generates $37,898.27 in interest and the second lien $11,775.29, for a combined five-year interest-and-fee total of $54,473.55.

Assumption scenario	Amount
Assumed first-lien balance	$250,058.92
First-lien rate / remaining term	3.25% / 25 years
Second lien (equity gap)	$30,000 at 9.5% / 10 years
Combined monthly principal and interest	$1,606.77
Assumption fee + estimated closing costs	$4,800
Five-year interest paid (both liens)	$49,673.56

Scenario B: a new loan at 7.18%

The alternative is financing the full $280,000 price with a new 30-year fixed loan. Freddie Mac's Primary Mortgage Market Survey put the national average 30-year fixed rate at 7.18% as of November 5, 2026, down for a third straight week from 7.24%. At that rate, principal-and-interest on a new $280,000 loan runs $1,896.82 a month — $290.05 more than the combined payment under assumption. Closing costs, estimated at a common rule-of-thumb of 2% of the loan amount, add $5,600 upfront. Interest paid over the first five years totals $97,878.26.

New-loan scenario	Amount
Loan amount	$280,000
Rate / term	7.18% / 30 years (Freddie Mac PMMS, Nov. 5, 2026)
Monthly principal and interest	$1,896.82
Estimated closing costs (2%)	$5,600
Five-year interest paid	$97,878.26

The real 5-year numbers, side by side

Add fees to interest and the comparison is stark: $54,473.55 in total interest-and-fee cost under assumption against $103,478.26 under a new loan — a five-year difference of $49,004.71 favoring assumption. Monthly, the buyer who assumes pays $290.05 less for principal and interest alone. Neither figure includes FHA mortgage insurance premiums, property taxes, homeowners insurance, or HOA dues, which apply similarly to both scenarios if the new loan is also FHA-insured, or would be absent from scenario B entirely on a conventional loan — a variable this analysis holds constant by comparing principal-and-interest only.

My own read is that the dollar gap is real and large enough to matter, but it is not, by itself, a reason to chase an assumption on any home that has one. The $49,000 figure assumes the buyer can produce $30,000 for the equity gap on terms no worse than a 9.5% second lien; borrowing that gap at a materially higher rate, or stretching to an interest-only structure, gives back a meaningful share of the advantage. Assumption is worth pursuing when the gap is small relative to the price, the buyer has cheap financing for it, and the rate differential is as wide as the 393-basis-point gap here (7.18% minus 3.25%) — not simply whenever a seller mentions their loan is assumable.

Where this can go wrong

Three things can erode or erase the advantage above. First, the equity gap is the binding constraint: Quicken Loans' assumption guide describes gaps that "often exceed the amount required for a down payment on a new loan," and financing that gap at a rate materially above the 9.5% used here shrinks the advantage — a gap financed at 13% instead of 9.5% adds roughly $60 a month to the second-lien payment alone. Second, approval is not guaranteed or fast: buyers must still clear FHA credit, debt-to-income and employment-history underwriting, and HUD publishes the debt-to-income limit as a grid rather than a single number. For manually underwritten FHA mortgages the maximum housing-payment and total-debt ratios are 31%/43% of effective income with no compensating factors, 37%/47% with one documented compensating factor (cash reserves, a minimal increase in the housing payment, or residual income) and 40%/50% with two, while a file whose minimum decision credit score is below 580, or that has no score, may not exceed 31%/43% at all (HUD FHA FAQ, updated October 8, 2026). And the Realtors' association has flagged that assumption processing routinely takes 30 to 60 days or longer, which can jeopardize a purchase timeline. Third, assumed FHA mortgage insurance premiums carry over with the loan — if the seller rolled an upfront premium into the balance, the buyer inherits that obligation along with the rate.

The underwriting standards above are set federally by HUD and apply nationwide. Closing-cost estimates, by contrast, vary by state and by title or escrow company, so the $3,000 and $5,600 figures should be treated as planning estimates, not quotes, and confirmed locally before a purchase contract is signed.

FAQ

Can anyone assume a seller's FHA loan?

No. The lender, not the seller, must approve the assumption, and the buyer must meet underwriting standards similar to a new FHA loan — generally a credit score of 580 or higher, a debt-to-income ratio of 43% or lower, and an intent to occupy the home as a primary residence.

How much does it cost to assume an FHA loan in 2026?

The servicer's assumption-processing fee is capped at $1,800, per FHA's 2024 policy update, which remains the current figure cited in 2026 guidance. On top of that, buyers typically pay title and recording closing costs, and must cover the equity gap between the purchase price and the remaining loan balance.

What is the equity gap in a loan assumption?

It is the difference between the home's purchase price and the remaining balance on the assumed loan. In the scenario above, a $280,000 sale price against a $250,058.92 remaining balance leaves a roughly $30,000 gap, which the buyer must cover in cash or with a separate loan.

Is assuming a 3.25% FHA loan always better than a new loan at 7.18%?

Not automatically. This analysis finds about $49,000 in five-year savings in one specific scenario, but the result depends heavily on how cheaply the buyer can finance the equity gap and on the size of that gap relative to the purchase price. A larger gap financed at a high rate can erase much of the advantage.

Where does the 7.18% comparison rate come from?

From Freddie Mac's Primary Mortgage Market Survey, which reported a 30-year fixed-rate mortgage averaging 7.18% nationally as of November 5, 2026, the third consecutive weekly decline.

Tip: Before you commit to either path, run the five-year numbers on your own loan balance — a financial calculator handles amortization and the equity-gap payment, and a budget planner keeps the closing costs and monthly difference in one place.
