Assumable Mortgages in California: How to Take Over a Low-Rate FHA or VA Loan

I’m Michael DiVita — DRE #01372066 | NMLS #241655, DiVita Home Finance (DRE #01818285 | NMLS #323700), Tiburon, CA. I’ve been in California mortgage lending since 2000 and founded DiVita Home Finance in 2007. I’m known as a creative mortgage broker: when a bank says no, I find the lender and the loan structure that can say yes. Assumptions only work when the equity-gap math works — I run those numbers before you write the offer. Call (800) 239-1103.

Millions of homeowners locked in rates around 3% in 2020–2021. With an assumable mortgage, a buyer can take over the seller’s existing loan — rate, remaining balance, and remaining term — instead of borrowing at today’s rates. The catch is that you have to qualify with the servicer and cover the difference between the loan balance and the price. This guide explains which loans are assumable, how FHA and VA assumptions work, how to find them, and how to finance the gap.

Which Loans Are Assumable?

• FHA loans — assumable by a buyer who qualifies with the servicer and will live in the home. For FHA loans originated since December 15, 1989, the servicer must review the buyer’s creditworthiness; investors generally can’t assume them.
• VA loans — assumable by a qualified buyer, veteran or civilian, with servicer (or VA) approval.
• USDA loans — assumable with approval, subject to USDA’s eligibility rules.
• Conventional loans — most fixed-rate conventional loans have a due-on-sale clause and aren’t assumable by a buyer. Some adjustable-rate loans allow assumption, and transfers between spouses or to heirs are handled under separate rules.

What It Can Save

Principal and interest on 30-year schedules, for illustration. On the same $700,000 balance, the 3% loan charges about $186,000 of interest over the first ten years versus about $460,000 at 7% — roughly $273,000 less. In real life the assumed loan has already been paid down for a few years, so its balance and remaining term will be smaller.

The Equity Gap — the Real Challenge

You take over only the existing balance. If the seller owes $450,000 and the price is $750,000, you need $300,000 at closing through cash, a second loan, or both. Assumptions pencil out best when:

• The seller bought recently with a small down payment, so the balance is close to the price.
• The price hasn’t risen far above the original purchase price.
• You have significant cash, or a second loan whose rate still leaves the blended cost well below a new first mortgage.

Financing the gap: a second mortgage behind the assumed loan is possible in many cases, but the servicer must allow it and the combined loan-to-value has to work. Some buyers use a HELOC on another property or other assets instead. I compare the blended payment — assumed first plus second — against a new loan so you can see whether the assumption actually wins.

How the Process Works

1. Find the loan. Confirm the seller’s loan type, servicer, balance, rate, and remaining term — ideally with a recent mortgage statement.
2. Contact the servicer early. Get the assumption package and fee information. FHA allows servicers to charge an assumption processing fee of up to $1,800; VA sets its own caps.
3. Write the offer with enough time. Assumptions usually take longer than a new loan; many take 45 to 90 days or more depending on the servicer. Build the timeline and an assumption contingency into the contract.
4. Qualify. You submit income, asset, and credit documentation; the servicer reviews you under FHA or VA credit standards.
5. Arrange gap funding in parallel.
6. Close through escrow. The seller should obtain a written release of liability — without it, the seller can remain liable for the loan.

VA Assumptions: What Buyers and Veteran Sellers Should Know

• Civilians can assume. You don’t need to be a veteran or have a Certificate of Eligibility.
• Seller’s entitlement: if a non-veteran assumes, the seller’s VA entitlement stays tied to the loan until it’s paid off. If a veteran buyer assumes and substitutes their own entitlement, the seller’s entitlement can be restored. Veteran sellers who plan to use a VA loan again should weigh this carefully.
• Funding fee: VA charges a 0.5% funding fee on assumptions unless the buyer is exempt.
• Approval: servicers with VA automatic authority can approve the assumption; others send it to VA.

FHA Assumptions: What to Know

• You’ll generally need to occupy the home as your primary residence.
• The loan’s FHA mortgage insurance continues. For loans with case numbers assigned on or after June 3, 2013 and less than 10% originally down, annual MIP lasts for the life of the loan.
• You step into the remaining term — you don’t restart a 30-year clock.

How to Find Assumable Homes

• Ask listing agents directly about the seller’s loan type, rate, and balance. MLS “financing” fields usually describe the financing a seller will accept, not the seller’s existing loan, so don’t rely on them alone.
• Use assumable-listing services such as Roam or AssumeList, which track listings with assumable FHA and VA loans.
• Target homes bought in 2020–2022 with FHA or VA financing — the lowest-rate vintage.
• Look near military communities — San Diego, Riverside, Monterey, Solano, and other base-adjacent areas have more VA loans.
• Sellers: if you have an assumable low-rate loan, advertise it. It can widen your buyer pool.

Frequently Asked Questions

Which mortgages are assumable?

FHA, VA, and USDA loans are generally assumable with approval from the servicer. Most fixed-rate conventional loans have a due-on-sale clause and can’t be assumed by a buyer, though some adjustable-rate conventional loans allow it.

Can a civilian assume a VA loan?

Yes. A non-veteran who qualifies can assume a VA loan. The veteran seller’s entitlement stays tied to the loan until it’s paid off, unless a veteran buyer substitutes their own entitlement.

How long does an assumption take?

Usually longer than a new loan — commonly 45 to 90 days or more, depending on the servicer. Contact the servicer early and give yourself enough time in the purchase contract.

How do I cover the equity gap?

With cash, a second mortgage behind the assumed loan if the servicer allows it, or other assets. Compare the combined payment on the assumed loan plus the second against a new loan to make sure the assumption actually saves money.

What does an assumption cost?

FHA allows servicers to charge an assumption processing fee of up to $1,800. VA charges a 0.5% funding fee unless the buyer is exempt, and servicers charge a capped processing fee. You’ll also pay normal escrow, title, and recording costs.

Does the seller stay liable after an assumption?

Only if they don’t get released. The seller should obtain a written release of liability from the servicer as part of the assumption; for VA loans, a veteran buyer substituting entitlement is what restores the seller’s entitlement.
