Assumable Loans in San Diego: A Guide for Buyers and Sellers
With the average 30-year fixed rate at 7.28% as of October 1, 2026 (Freddie Mac), an assumable loan can be the single biggest money-saver in a San Diego purchase. Thousands of local homeowners hold FHA and VA loans written at 2.5%–3.5% in 2020–2021. In the right deal, a buyer can take over that rate instead of starting fresh at today's prices.
San Diego is unusually rich in these loans. Our large military and veteran community means a meaningful share of homes, from Clairemont to Carmel Valley to University City, carry VA financing. This guide explains how assumptions work, what buyers and sellers should watch for, and walks through a sample assumption on a detached home in the UTC area.
What is an assumable loan?
An assumable loan is an existing mortgage that a buyer takes over from the seller, keeping the original interest rate, remaining balance and remaining term. There is no new loan. The buyer signs assumption documents, the servicer approves them, and the loan continues in the buyer's name.
Which loans can be assumed?
VA loans: yes. Any qualified buyer can assume one, veteran or not. The buyer pays a 0.5% VA funding fee on the remaining balance, plus a capped processing fee.
FHA loans: yes. Any creditworthy buyer who will live in the home can assume one. The servicer's processing fee is capped at $1,800, and FHA mortgage insurance carries over to the new owner.
USDA loans: yes, with approval. The buyer must meet USDA program rules. Processing fees commonly run $300 to $500.
Conventional loans: generally no. Most Fannie Mae and Freddie Mac loans have a due-on-sale clause, which requires the loan to be paid off when the home sells.
One important catch: you assume the loan balance, not the home's price. The difference between the price and the balance, called the equity gap, must be paid in cash or covered with a second loan. In San Diego, where values have climbed since 2020–2021, that gap is often large.
For buyers: what to know
The payoff is a rate you can't get today. Taking over a 2.75% loan instead of borrowing at 7%+ can cut a San Diego payment by thousands of dollars a month.
You still have to qualify. The servicer underwrites your credit, income and debt-to-income ratio, much like a new loan.
Plan for the equity gap. Bring cash, or pair the assumption with a second mortgage. The second carries today's rates, so the blended rate is what matters.
Costs are lower than a new loan. No origination fee or points. A VA assumption costs a 0.5% funding fee on the balance, which cannot be financed. FHA processing is capped at $1,800, but FHA mortgage insurance usually transfers with the loan.
You inherit a shorter term. A 2021 loan has about 25 years left, so you build equity faster.
Expect a longer escrow. Servicers must decide on a complete package within 45 days, but 60–90 days from acceptance to closing is realistic. Build that into your contract and rate expectations.
It must be your home. FHA and VA assumptions require owner-occupancy; investors don't qualify.
For sellers: what to know
A low-rate assumable loan is a marketing asset. It can widen your buyer pool and support a stronger price, because buyers are shopping by monthly payment.
Advertise it. Most listings never mention assumability. Put "assumable VA loan at 2.75%" in the remarks and marketing.
Get a Release of Liability. Without a formal release from the servicer (or VA), you can stay on the hook if the buyer later defaults. Make it a condition of closing.
VA sellers: protect your entitlement. If a non-veteran assumes your VA loan, your entitlement stays tied to that loan until it is paid off. That can limit your next VA purchase, which matters for military families on PCS orders. If the buyer is an eligible veteran who completes a Substitution of Entitlement (VA Form 26-8106), your entitlement is restored.
Expect a longer timeline. Plan your move and any next purchase around a 60–90 day escrow.
Price for the gap. Buyers need cash or a second loan to cover your equity. Pricing and terms that make the gap workable will widen your buyer pool.
Example: assuming a VA loan on a detached home in UTC
In this example, my buyers save about $1,670 a month versus a new loan, roughly $20,000 a year. Names and figures are illustrative, but the structure is exactly how these deals come together.
The home. A 4-bedroom detached home in University City, a few minutes from UTC, Westfield UTC and the UCSD/Torrey Pines biotech corridor. The seller, a Navy officer with PCS orders, bought in early 2021 with a $1,150,000 VA loan at 2.75%. After 67 payments the balance was about $1,001,000.
My buyers. A veteran and his spouse, both working in Sorrento Valley. They had $250,000 in savings and were comparing new jumbo financing at today's rates.
Option 1: Assume the VA loan plus a second loan. On a $1,725,000 purchase with $250,000 down, my buyers take over the $1,001,000 balance at 2.75%. A $474,000 second loan at an assumed 8.75% covers the rest of the equity gap. The blended rate is about 4.68%, and principal and interest come to about $8,420 a month. Upfront loan costs are a $5,005 VA funding fee (0.5% of the balance) plus the servicer's processing fee.
Option 2: Get a new loan at today's rate. Same price, same $250,000 down, but a new $1,475,000 loan at 7.28%. Principal and interest come to about $10,090 a month. Upfront costs include origination, any points and a new VA or jumbo loan fee.
The difference: about $1,670 a month, or roughly $20,000 a year, in favor of the assumption.
Payments exclude taxes and insurance. The 7.28% figure is the Freddie Mac national average for the week of October 1, 2026; jumbo pricing varies.
How the deal came together.
Found the loan. The listing mentioned the VA loan, and I confirmed the rate, balance and servicer with the listing agent before we wrote.
Wrote the offer around the assumption. We made it contingent on servicer approval and gave a 75-day escrow to fit the seller's orders.
Lined up the second loan early. My buyers' lender approved a second mortgage to cover the equity gap, coordinated with the servicer's timeline.
Submitted the assumption package. Income, assets, credit and my buyer's Certificate of Eligibility went to the servicer in week one.
Substituted entitlement. Because my buyer is a veteran, he substituted his VA entitlement, restoring the seller's for his next purchase. That made our offer stronger than a non-veteran's.
Closed. The seller received a Release of Liability, my buyers took over the 2.75% loan with about 25 years left, and the second loan funded the gap.
The takeaway. Even with a second loan at a higher rate, the blended cost beat a new loan by more than 2.5 points. And because the assumed loan has a shorter remaining term, my buyers build equity faster from day one.
How to find an assumable home in San Diego
Most assumable loans are hiding in plain sight, because listings rarely flag them. Here's how to surface them:
Search listing remarks for "assumable," "VA loan" or "FHA loan."
Focus on homes bought or refinanced in 2020–2022, when rates were lowest.
Look near military hubs and first-time-buyer neighborhoods, where VA and FHA loans are common.
Ask the listing agent directly for the loan type, rate, balance and servicer before you write an offer.
