Assumable mortgages are the one legitimately powerful buyer strategy that has emerged from the rate cycle. The math is simple: if a seller took out a VA or FHA loan at 2.5 to 4 percent during the 2020 to 2022 window, and you can take that loan over instead of getting a new one at today's 6 to 7 percent market rate, you save hundreds of dollars a month and tens of thousands over the life of the loan. In Austin, the inventory on this page updates from ACTRIS MLS every fifteen minutes, and the list above is what is currently available.
What almost no other page on this topic will tell you honestly: assumption is not free money. There is an equity gap between the loan balance and the sale price that has to be paid at closing, the timeline is materially longer than a standard purchase, and the servicer holds veto power on the approval. This page walks through the real mechanics so you know what you are actually buying into.
Which loans are actually assumable in Austin
VA
Any VA loan is assumable subject to servicer approval. Non-veteran buyers can assume but the seller's VA entitlement stays tied to the property until the loan is paid off. A veteran buyer with entitlement can substitute their own, freeing the seller.
FHA
FHA loans originated after December 1989 are assumable subject to full FHA underwriting of the buyer. Owner-occupancy is required. Simpler than VA on the entitlement side but the same 45 to 90 day timeline.
USDA
USDA loans are assumable but only exist on rural-designated properties, which in the Austin metro means a handful of Bastrop, Lockhart, and Elgin properties. Rare inventory, subject to USDA rural eligibility.
Conventional Fannie Mae and Freddie Mac loans are almost never assumable in real practice. Their notes carry a due-on-sale clause that lenders enforce whenever a home changes hands. If a seller advertises a conventional loan as assumable, verify with the specific servicer before you get excited. Nine times out of ten the advertised assumption falls apart when the servicer says no.
How an Austin assumption actually closes
Verify the loan is actually assumable and get the current balance
Before writing an offer, the seller (or listing agent) gets a written statement from the loan servicer confirming the assumable status, current principal balance, interest rate, remaining term, and monthly PI. This is not the same as what the seller says at the kitchen table. Servicer-confirmed.
Do the equity-gap math and decide how to fund it
Assumed balance plus your funds equals purchase price. If the assumed balance is $325K and the price is $500K, you need $175K plus closing to make the numbers work. Options: cash, seller financing on the gap, a small first-position purchase-money second lien, or some combination. Blended-rate math on the second-lien piece changes the true cost.
Write the offer with an assumption contingency
Texas contract with a financing addendum that specifies loan assumption rather than new financing. The addendum needs to reflect the actual assumed rate and terms, and the option period should be long enough to survive step 4.
Servicer underwrites you at the assumed balance
VA and FHA servicers run credit, income, and asset underwriting on the buyer for the assumed loan amount. This is a full underwrite, similar in scope to a refinance. It takes what it takes, and most sellers who go into contract without pre-arranging the assumption package waste 30 to 60 days here.
Fund the equity gap and close at the Texas title company
Once the assumption is approved, closing runs like any other Texas purchase. Title commitment, survey, settlement statement, funding of the equity gap, funding of any second lien, recording. The Texas title side is not the constraint here. The servicer is.
The single biggest mistake I see on assumable deals in Austin is a buyer who writes an offer on the advertised rate before verifying it with the servicer. Verify first, offer second. That order is not optional.
The equity gap is the real question
Every Austin buyer who calls me about an assumable listing asks the same first question, which is a version of "how do I get the rate." The right first question is different: how do I fund the equity gap. On a $500K Austin home with a $325K assumable balance, you need $175K plus roughly $8K to $15K of closing costs. That is real cash. Buyers cover the gap through three main paths:
- All-cash gap. If you have $175K plus closing in cash, the assumption is pure upside. You inherit the low rate and your effective rate on the whole purchase equals the assumed rate. This is the cleanest path and it produces the biggest lifetime savings.
- Purchase-money second lien. A second-position loan from the same or a different lender covers the gap. Second liens today run 8 to 10 percent, materially higher than a first mortgage, so your blended rate on the total purchase price is a weighted average of the assumed rate and the second-lien rate. The math still often works, but it needs to be run before you write the offer.
- Seller financing on the gap. Some sellers will carry a note on the equity gap at a rate between the assumed rate and market. This is a real option, especially on longer-listed inventory, but it depends on the seller's own cash needs and their comfort holding paper.
Which path is right depends on your specific cash position and the specific listing. My default when I represent a buyer on an assumable is to run all three paths on paper before we write the offer so you know what you are actually committing to.
What is different about doing this in Texas
Federal loan assumption rules are the same in Texas as anywhere else in the United States. What is different is the transaction wrapper around it.
- Texas title company handles the close. Standard title work, standard settlement, standard funding. The title company will need the assumption approval package from the servicer before they can prepare the CD (Closing Disclosure) and coordinate funding.
- Texas homestead protections still apply. Homestead law affects some second-lien loan products, particularly home equity loans and HELOCs. If you plan to cover the gap with a homestead-secured second, know the Texas 80 percent LTV cap and the specific home equity loan rules before you commit.
- Property tax reassessment still hits. Assuming a loan does not exempt you from Texas property tax reassessment on the purchase. Travis County and surrounding counties will reassess to your purchase price in the following tax year, and the tax carry adjustment is real.
- No state income tax. Texas has no state-level income tax, which is a rounding error on an assumption specifically but is meaningful context for out-of-state buyers looking at Austin assumable listings as part of a broader relocation.
Bottom line
Assumable mortgages are one of the few genuinely powerful buyer strategies in a high-rate market, and the Austin inventory that supports them is real if thin. What separates a successful assumption from a wasted 90 days is doing the servicer verification and the equity-gap math before you write the offer, not after.
