When you assume a mortgage, you're not just inheriting a lower rate—you're also writing several checks to make the transfer official. The fee structure varies by loan type and lender, but understanding each component helps you model the true cost of stepping into someone else's financing.
Assumption processing fee
The servicer handling the assumption charges a processing fee to underwrite you as the new borrower and transfer the loan. FHA and USDA assumptions typically run $500 to $900; VA assumptions range from $300 to $500, though some servicers charge more. This fee is non-refundable once the servicer pulls credit and begins review. It covers file setup, credit analysis, and legal documentation—not just paperwork shuffling.
VA funding fee
If you assume a VA loan and you are not a veteran or eligible service member, you owe a funding fee equal to 0.5 percent of the remaining loan balance. On a $300,000 balance, that's $1,500 due at closing. Veterans assuming a VA loan pay no funding fee. These figures are illustrative; rates and products are subject to change and this is not a commitment to lend. The fee can be financed into the new loan only if the appraisal supports it and the lender allows—most assumptions close with the fee paid in cash.
Credit-package and third-party fees
You still undergo full credit qualifying. Expect to pay for a tri-merge credit report ($30–$75), an appraisal if the lender orders one ($400–$700), and possibly a verification-of-employment fee. Some servicers bundle these into a flat application package; others itemize. Assumption does not bypass underwriting standards—the servicer evaluates income, debt ratios, and credit score exactly as they would for a purchase.
Gap financing and title charges
If the seller has $80,000 in equity and you assume their $220,000 loan, you need to deliver that $80,000 somehow—either cash or a second mortgage. A second lien carries its own origination fee (often 1 percent), appraisal, title policy, and closing costs. Title and escrow fees for the assumption itself run $800 to $1,500, covering the deed transfer, title search, and recording. Each county charges a different recording fee; your settlement statement will itemize it.
Rate and terms: locked at origination
The interest rate and monthly payment you assume are set by the original loan documents—not by today's market or your credit profile. If the seller's note says 3.25 percent, you pay 3.25 percent. No negotiation, no rate lock, no buydown. Review the original loan agreement before you commit; some older notes contain due-on-sale clauses that technically prohibit assumption even on government loans, though those are rare.
The Alliance take
Assumptions save money when the existing rate sits well below market, but the combined fees, gap financing, and title work can add $5,000 to $10,000 to your acquisition cost. Run the numbers against a conventional purchase before you decide. If an assumption fits your scenario, start an application and we'll coordinate with the servicer from day one.
