Is taking over the seller’s 3% loan worth it?

Assume the loan

$232,099

Assuming the seller’s 3.25% loan saves $232,099 in lifetime interest vs a new 6.75% loan of the same size over the same remaining term (you cover the equity gap in cash). You’ll need $122,200 in cash at closing ($120,000 equity to the seller + $2,200 in fees).

How loan assumption works

Only VA, FHA, and USDA loans are assumable. Conventional loans contain a "due-on-sale" clause that triggers the full balance when the property transfers.

You still have to qualify. The lender will run your credit, verify income/assets, and either approve or deny the assumption. Standards are similar to a new loan.

You inherit the seller’s remaining term. If the seller is 5 years into a 30-year loan, you start with 25 years left, not a fresh 30. This often shrinks the savings substantially because the rate-arbitrage period is shorter.

The equity gap: if the home has appreciated, the sale price often far exceeds the loan balance. You make up the difference in cash at closing. Example: $500k home with $200k loan balance = you bring $300k cash. This is why assumptions often only work in flat markets or with a second mortgage to bridge the gap.

If a non-veteran assumes a VA loan, the seller’s VA entitlement stays tied up until the loan is paid off. Most veteran sellers won’t agree to this. A veteran buyer can free the seller’s entitlement only by substituting their own entitlement as part of the assumption.

Millions of homeowners locked in sub-3.5% rates in 2020-2021, and with new-loan rates well above that, those loans are worth a lot, which is why assumptions picked up in 2024-2026. The hard part is finding a deal where the equity gap is bridgeable.

Process: seller’s servicer must approve the assumption. Typical timeline 30-60 days. Costs modeled at each program’s maximum: VA, a $300 processing fee (VA has also allowed a regional add-on since 2024) plus the 0.5% funding fee unless you’re exempt; FHA, a processing fee capped at $1,800; USDA, a new 1% upfront guarantee fee on the remaining balance plus the servicer’s processing fee (not capped by USDA, not included here). For FHA the servicer must complete a full creditworthiness review. USDA buyers must also meet USDA’s income and property eligibility rules.
