Can you take over the seller's mortgage rate when you buy a home in Flower Mound?

Sometimes, yes. If the seller's loan is FHA, VA, or USDA, the loan is assumable: you take over the balance, the rate, and the remaining term, with the servicer's approval. Conventional loans, which are most of the loans in Flower Mound, carry a due-on-sale clause and cannot be assumed. The catch is the equity gap. You assume the loan balance, not the price, so the difference between what the seller owes and what you are paying has to come from cash, a second lien, or seller financing. In Texas the deal runs on the TREC Loan Assumption Addendum (No. 41-3), and the servicer, not the title company, controls the clock.

Here is the version of this question I actually hear in Flower Mound: "The listing says the seller has a 2.875% loan. Can we just take that over?" With Freddie Mac's 30-year average sitting at 7.40% the week of October 15, 2026, that is not a dumb question. It is one of the few financing moves left that can cut a payment by several hundred dollars a month without a rate buydown or a bigger down payment.

But an assumption is a specific transaction with its own paperwork, its own fees, and its own ways to fall apart. Let's walk through what is assumable, what the equity gap does to your cash, how the Texas contract handles it, and how to spot one of these loans in the first place.

Which Flower Mound loans can actually be assumed

Three loan types are assumable: FHA, VA, and USDA. That is the whole list. A conventional loan, which is any loan sold to Fannie Mae or Freddie Mac, and every jumbo loan, contains a due-on-sale clause. The lender can call the full balance the moment the title changes hands, and they will, because they would rather lend that money out again at today's rate.

That matters more in Flower Mound than in a lot of places. Jumbo and conventional financing dominates above the conforming limit, and most of the $800,000 to $1.5M homes in Bridlewood and Wellington were bought with loans that cannot be assumed. The assumable inventory here skews toward the $400,000 to $700,000 band, often 2020 and 2021 purchases where an FHA or VA buyer locked a rate under 3.5%. If you are shopping in that band, an assumption is worth asking about on every listing.

A few rules by loan type:

• FHA. Any FHA loan made after December 15, 1989 can be assumed only by a buyer the servicer credit-qualifies. Expect the same kind of underwriting as a new FHA loan: credit, income, debt ratios, and a commitment to live in the home. The annual mortgage insurance premium stays attached to the loan at whatever rate it was set when the loan was made, so your payment includes it. HUD raised the cap on what a servicer can charge for an assumption to $1,800 in 2024.
• VA. You do not have to be a veteran to assume a VA loan, and that surprises people. The buyer pays a VA funding fee of 0.5% of the balance being assumed (unless exempt), plus a servicer processing charge that VA caps in the low hundreds. The complication is the seller's entitlement, which I cover below.
• USDA. Assumable in theory, but most USDA assumptions are "new rates and terms," meaning you lose the old rate. The rate-preserving version is narrow and usually limited to family transfers. There is not much USDA inventory inside Flower Mound town limits anyway.

One more thing to know before you get excited about a listing: the seller usually has no idea their loan is assumable. The first time many of them hear it is from a buyer who asks.

The equity gap is the real test

You are not assuming the purchase price. You are assuming the loan balance. Everything between the balance and the price is the seller's equity, and the seller gets that at closing, in cash, from you.

Here is what that looks like on a real Flower Mound number. Redfin puts the Flower Mound median sale price at $642,694 as of September 2026, so let's use a $640,000 sale.

Say the seller bought in 2021 for $520,000 with an FHA loan at 3.5% down, roughly a $500,000 loan at 2.875%. After five years of payments the balance is about $445,000, and the principal and interest payment is about $2,082 a month.

• The gap: $640,000 price minus $445,000 balance = about $195,000 owed to the seller at closing.
• If you bring 20% down ($128,000): you still need roughly $67,000 more. A second lien on that piece at around 8.5% over 20 years runs about $580 a month.
• Your combined payment: about $2,082 plus $580 = roughly $2,660 in principal and interest.
• The alternative: a new 30-year loan on $512,000 at 7.40% is about $3,545 a month.

That is close to $880 a month in your favor, before taxes, insurance, and FHA mortgage insurance, which apply either way. Over five years it is more than $50,000. That is the reason to go through the extra work.

The gap is also the reason most assumptions never happen. If the seller bought in 2019 and the home has appreciated $250,000, the buyer needs that much in cash or in a second lien, and second-lien lenders who will sit behind an assumed FHA or VA first are not on every corner. Ask early. A buyer who can cover the gap with proceeds from their own sale is the buyer these deals are built for, which is why the bridge loan and sale contingency question usually shows up in the same conversation.

Three ways to fund the gap, from cleanest to messiest:

• Cash. Usually equity from the home you just sold. Simplest, fastest, no second underwriting.
• A second lien from a lender. A home equity loan or a purpose-built assumption second. Current rates apply to that piece only, so the blended rate still beats a new first mortgage as long as the second stays a minority of the total.
• Seller financing on the gap. The seller carries a note for part of their equity. Workable, but it needs a Texas attorney, and a seller who still wants to be paid in full at closing will say no.

How the Texas contract and the servicer's clock work

An assumption still runs on the standard TREC One to Four Family Residential Contract. Paragraph 4 is where the financing is described, and when a loan is being assumed the contract has to attach the TREC Loan Assumption Addendum, No. 41-3. Mandatory, not optional, under 22 TAC 537.48.

That addendum does four things you need to understand before you sign it:

• You deliver your credit package to the seller. Within a stated number of days after the effective date, you hand over a credit report, employment and income verification, verification of funds, and a current financial statement. The seller then gets a short window to reject your credit in their sole discretion and terminate. Miss the deadline and the seller can terminate and keep your earnest money.
• The balance and rate are pinned. The addendum states the loan balance and rate you are assuming. If the actual payoff balance at closing differs, the price adjusts by the difference, and past a stated variance either side can terminate. If the servicer requires a higher rate than the one written in, you can walk with your earnest money.
• The assumption fee has a ceiling. The addendum names a fee amount. If the servicer wants more and the seller will not pay the excess, you can terminate.
• The seller stays liable unless released. This is the part sellers miss. Assuming the loan does not take the seller's name off the note. The seller stays on the hook for your payments unless the servicer issues a written release, which is why the addendum requires a vendor's lien and a deed of trust in the seller's favor unless that release is in hand.

The release lives on a second form, the TREC Addendum for Release of Liability on Assumed Loan and/or Restoration of Seller's VA Entitlement, No. 12-3. It sets a deadline to apply, makes the seller pay for the release, and lets the parties pick what happens if the release is not approved by closing: terminate with earnest money back to the buyer, or close anyway. A seller who closes without the release has handed a stranger their credit.

The VA entitlement problem. If a non-veteran assumes a VA loan, the seller's VA entitlement stays tied to that loan until it is paid off. The seller may not be able to use a VA loan on their next purchase, or may only have partial entitlement left. The only way to restore it is for the buyer to be an eligible veteran who substitutes their own entitlement. Form 12-3 covers that request, and it is a real negotiating point for a veteran seller in Flower Mound who is planning to buy again with VA.

The servicer controls the clock. HUD's servicing rules give an FHA servicer 45 days from a complete file to finish the credit review, and VA assumptions commonly run 45 to 90 days. In practice both run longer, because servicers have little incentive to hurry. A buyer in NPR's February 2026 reporting was told 1,500 people were ahead of him in one servicer's queue. Plan for 60 to 90 days to close, write that into Paragraph 9, and expect to request an extension at least once. Your option period runs the same as any other contract, so get the inspection done early rather than waiting on the servicer.

For sellers, an assumption changes the net too. You still owe the costs in the Flower Mound net proceeds math, and you are adding the release fee and a longer timeline. What you gain is a buyer who may be willing to pay closer to list because the payment works. On a listing with a sub-4% assumable loan, I will say so in the MLS remarks on purpose, because it widens the buyer pool.

How to spot an assumable loan on a Flower Mound listing

You will rarely see "assumable" in the public remarks. Here is how to find one:

• Ask the listing agent two questions: what type of loan does the seller have, and when did they buy? A 2020 or 2021 FHA or VA purchase is the profile you want.
• Check the deed of trust. Denton County deed records are public. An FHA or VA deed of trust is labeled as such on the first page, and the recording date tells you the era of the rate.
• Use the search tools. Roam and AssumeList both flag assumable listings from loan records. NPR's reporting found Roam listed 433 Houston homes with assumable loans at 3% or lower while a Zillow search of the same kind returned three, because Zillow relies on sellers to self-report.
• Read the MLS financing fields. The NTREIS listing form carries proposed financing and the seller's loan type when the agent fills it in. Most do not. The ones who do are telling you something.

Then run the gap math before you fall in love with the rate. A 2.875% loan with a $300,000 equity gap and no second-lien source is a nice story, not a plan.

This is exactly the kind of question I walk buyers through before we write the offer. The rate is the headline, but the cash to close, the seller's release, and a 90-day timeline are the parts that decide whether the deal actually happens. If you are selling a Flower Mound home with an FHA or VA loan from 2020 or 2021, your loan may be one of the most marketable things about your house, and almost nobody is telling you that.

Frequently Asked Questions

Can I assume a conventional mortgage in Texas?

Almost never. Conventional loans sold to Fannie Mae or Freddie Mac, and all jumbo loans, carry a due-on-sale clause that lets the lender call the full balance when the home is sold. The exceptions are family transfers, divorce, and inheritance, not an arm's-length sale. Only FHA, VA, and USDA loans are assumable in a normal purchase.

Do I have to be a veteran to assume a VA loan in Flower Mound?

No. A non-veteran can assume a VA loan if the servicer approves their credit and income and they will occupy the home. The buyer pays a 0.5% VA funding fee on the balance assumed. The seller's VA entitlement stays tied to the loan until it is paid off unless the buyer is an eligible veteran who substitutes their own entitlement.

How long does a mortgage assumption take to close?

Plan on 60 to 90 days. HUD gives an FHA servicer 45 days from a complete file to finish the credit review, and VA assumptions commonly run 45 to 90 days, but servicer backlogs regularly push both past that. Write a realistic closing date into the contract and expect to extend at least once.

What is the equity gap on an assumable mortgage?

It is the difference between the loan balance you assume and the price you pay, and it goes to the seller in cash at closing. On a $640,000 Flower Mound home with a $445,000 balance, the gap is about $195,000. You cover it with cash, a second lien at current rates, or seller financing on part of it.

Does the seller stay liable after I assume their loan?

Yes, unless the servicer issues a written release of liability. The TREC Loan Assumption Addendum (41-3) requires a lien in the seller's favor until that release exists, and TREC Form 12-3 is how the parties apply for it and decide what happens if it is not approved by closing. Sellers should never close an assumption without the release in hand.

Where this leaves you

An assumable loan can shave hundreds of dollars a month off a Flower Mound payment, but only if you can cover the equity gap, the servicer approves you, and the seller gets a written release. Those three things are the whole deal.
