How Mortgage Assumption Works in Texas: Steps, Costs, Timeline
Freddie Mac’s Primary Mortgage Market Survey put the average 30-year fixed rate at 6.49 percent for the week ending July 9, 2026. Meanwhile, millions of FHA and VA loans originated in 2020 and 2021 still carry rates near 3 percent. When a Texas seller has one of those loans, a buyer can sometimes step into it through a mortgage assumption instead of financing the purchase at today’s pricing. I get asked about assumptions almost every week now, and most buyers have heard the concept but have no idea how the process actually runs.
That gap matters because assumptions are slow, paperwork-heavy, and full of small tripwires. Buyers who go in expecting a normal 30-day close get frustrated. This post is the checklist I walk people through: the steps in order, what each one costs, and how long the whole thing takes in Texas.
Key points:
- Only certain loans can be assumed. FHA and VA loans generally allow it; most conventional loans do not.
- You qualify with the seller’s loan servicer, with full credit and income review, subject to credit, income, and property qualifications.
- Assumption processing fees are modest: HUD caps the FHA assumption fee at $1,800, and VA assumptions typically involve a 0.5 percent funding fee plus a small processing charge.
- The hard part is the equity gap. You must cover the difference between the price and the loan balance with cash or secondary financing.
- Plan on 45 to 90 days from application to closing, sometimes longer.
- Sellers should insist on a formal release of liability at closing.
What is a mortgage assumption and which loans qualify?
A mortgage assumption is a transaction where the buyer takes over the seller’s existing loan, keeping its rate, balance, and remaining term, instead of originating a new mortgage. In Texas, FHA and VA loans are generally assumable with servicer approval. Most conventional loans contain a due-on-sale clause that blocks assumption, so if the seller has a conventional loan, this path is usually closed.
The buyer still has to qualify. The servicer reviews credit, income, and debt just like a lender would on a new loan. On a VA assumption there is an extra wrinkle: the seller’s VA entitlement stays tied up in the loan unless the buyer is also an eligible veteran who substitutes their own entitlement. I have seen Texas veterans agree to an assumption without understanding that piece, and it limits their ability to use a VA loan on their next purchase.
The assumption checklist: 7 steps in order
1. Confirm the loan is assumable. Ask the seller for their most recent mortgage statement and note the servicer and loan type. FHA case numbers and VA loan numbers are usually visible on the statement. If the listing says “assumable loan,” verify it anyway.
2. Get the payoff and rate details in writing. You need the current balance, the rate, the remaining term, and the monthly payment including escrow. The economics of the whole deal live in these four numbers.
3. Size the equity gap before you fall in love with the house. Purchase price minus loan balance equals the cash you need beyond the loan. A $335,000 home (the Texas statewide median per the Texas Real Estate Research Center’s April 2026 data) with a $220,000 remaining balance leaves a $115,000 gap. If you cannot cover the gap with savings or a second lien, stop here.
4. Request the assumption package from the servicer. The seller usually has to initiate this. Servicers move at their own pace, and some route assumption requests through a dedicated department with its own queue. Get the request in early.
5. Complete the servicer’s underwriting. Expect the same documentation as a normal mortgage application: pay stubs, W-2s or tax returns, bank statements, and a credit pull. A buyer in San Antonio I talked with last month assumed this step would be lighter than a regular approval. The document list matches a regular approval, and the review sits in a slower queue on top of it.
6. Line up the gap funds or secondary financing. Cash is cleanest. Some buyers use a second lien to bridge the gap, but the second comes at today’s rates and needs servicer and lender coordination. Blend the two rates to see the true cost of the deal, and compare that blend against a standard purchase loan at current pricing on my Texas mortgage rates page.
7. Close, and get the release of liability. At closing the buyer signs the assumption agreement and the seller should receive a formal release of liability from the servicer. Without it, the original borrower can remain on the hook if the new owner ever defaults. Sellers, do not skip this document.
What does it cost to assume a mortgage in Texas?
Assumption fees are small compared with the closing costs on a new loan. HUD caps the fee a servicer can charge to process an FHA assumption at $1,800 under its 2024 policy update. VA assumptions carry a funding fee of 0.5 percent of the loan balance plus a processing fee that VA rules keep modest, typically around $300 plus the cost of a credit report. You will still pay for title work, escrow setup, and recording. Here is how the two programs compare:
| Item | FHA assumption | VA assumption |
|---|---|---|
| Servicer processing fee | Capped at $1,800 by HUD | Typically around $300 plus credit report |
| Government fee | None beyond ongoing MIP | 0.5% funding fee on the balance (unless exempt) |
| Mortgage insurance | Existing FHA MIP continues with the loan | None |
| Buyer qualification | Full credit and income review by servicer | Full review; entitlement substitution if buyer is an eligible veteran |
| Appraisal | Generally not required | Generally not required |
One item buyers overlook: an assumed FHA loan keeps its existing mortgage insurance premium (MIP, the monthly insurance charge on FHA loans). If the loan closed after mid-2013 with less than 10 percent down, that MIP runs for the life of the loan. Factor it into the payment comparison. If you are weighing a fresh FHA loan instead, the 2026 FHA loan limits in Texas give you the current ceilings.
How long does a mortgage assumption take?
Plan on 45 to 90 days from the assumption application to closing, and build that into the purchase contract. Servicers process assumptions in a separate queue from new originations, they earn no origination revenue on them, and staffing for assumption departments is thin. Sixty days is a realistic midpoint; I have seen Houston deals stretch past 90 when the servicer asked for documents twice.
Two things protect you. First, write a realistic closing date into the contract, with the seller’s agreement on what happens if the servicer runs long. Second, submit a complete document package the first time. Most assumption delays trace back to underwriting requests that sat unanswered in someone’s inbox.
When an assumption beats a new loan, and when it does not
The bigger the rate spread and the smaller the equity gap, the better the assumption looks. Taking over a 3.25 percent loan when the market is near 6.5 percent can cut hundreds of dollars from the monthly payment on the same house. At Mortgage Austin we see the opposite case just as often: the seller’s balance is low, the gap is enormous, and the buyer would need a large second lien at today’s rates to bridge it. Once you blend the old first with a new second, the advantage can shrink to nothing.
Run both versions of the deal side by side: the assumption with its blended cost and 60-day-plus timeline, and a standard Conventional, FHA, or VA purchase at current pricing with a 30-day close. If you want help with that comparison, my Texas down payment breakdown covers the cash-to-close side of a traditional purchase.
Frequently Asked Questions
Can I assume a conventional mortgage in Texas?
Usually no. Most conventional loans include a due-on-sale clause that lets the lender demand full payoff when the property transfers, which blocks assumption. FHA and VA loans are the main assumable types, and both require the servicer to approve the new borrower.
Do I need good credit to assume a mortgage?
Yes. The servicer runs a full credit and income review, similar to a new mortgage application. Approval is subject to credit, income, and property qualifications, and each servicer sets its own minimum credit standards within FHA or VA guidelines.
How much does it cost to assume an FHA loan?
HUD caps the servicer’s assumption processing fee at $1,800 under its 2024 policy update. You will also pay standard title, escrow, and recording charges, and the loan’s existing FHA mortgage insurance premium continues with the loan after you assume it.
How do I cover the difference between the price and the loan balance?
You bring the difference as cash at closing or finance it with a second lien. On a $335,000 Texas home with a $220,000 assumable balance, that gap is $115,000. A second lien prices at today’s rates, so blend the two rates before deciding the assumption is a better deal.
Does the seller stay liable after I assume their loan?
Only if the release of liability is skipped. A formal release from the servicer at closing removes the seller from responsibility for the loan. Sellers should treat that document as a hard requirement of the deal.
How long does a mortgage assumption take in Texas?
Most assumptions run 45 to 90 days from application to closing, with 60 days as a realistic midpoint. Servicers work assumptions in a separate, slower queue than new loans, so write a realistic closing date into the purchase contract from the start.
