TEXAS HOME BUYING AND SELLING GUIDES
Subject-to vs. seller financing vs. mortgage assumption
These arrangements differ in who owes the debt and whether the existing lender agrees to a change.
Before comparing interest rates or monthly payments, ask whose name remains on each loan and when ownership transfers.
A deed and a mortgage obligation are separate parts of the transaction.
Quick answer
Subject-to, seller financing and assumption describe different obligations.
Subject-to generally leaves the existing debt in the seller’s name; seller financing creates a buyer debt to the seller; an assumption involves the lender accepting the buyer under its requirements.
Always verify any release of the seller in writing.
Subject-to: the existing loan remains
In a subject-to purchase, the buyer takes ownership subject to an existing mortgage while the original borrower remains responsible to that lender.
A private promise by the buyer to make payments does not substitute the buyer as the lender's borrower.
A due-on-sale clause may allow the lender to demand repayment after a transfer.
Federal law protects certain types of transfers, but do not assume an ordinary subject-to sale qualifies.
Obtain independent advice about the actual loan and proposed transfer.
Seller financing: the buyer owes the seller
The seller finances some or all of the purchase price under a new repayment agreement.
The parties need to specify when the deed transfers and how repayment is secured.
If an earlier mortgage remains, it introduces additional obligations and may create a wrap structure.
Texas regulates wrap mortgage lending separately.
A label such as owner finance does not explain whether another lender can foreclose or whether the transaction complies with the applicable rules.
Assumption: the lender accepts a new borrower
For a mortgage assumption, the creditor expressly agrees in writing to accept a new consumer as a primary obligor on the existing residential mortgage transaction.
Merely accepting payments from someone else does not automatically create that agreement.
Ask the servicer whether the loan permits assumption, what review is needed, and which terms remain.
Separately confirm whether the original borrower receives a written release from liability.
Check the cash needed as well as the payment
A loan balance may be far below the agreed price.
Ask how the difference will be funded, which costs are due at closing, and whether any additional financing is allowed.
Compare the complete payment obligations if more than one loan is involved.
| Structure | Who owes whom? | What to verify |
|---|---|---|
| Subject-to | Original borrower still owes the existing lender | Transfer restrictions and ongoing seller liability |
| Seller financing | Buyer owes the seller; any old debt needs separate treatment | Deed timing, loan security and existing-loan payoff plan |
| Lender-approved assumption | Buyer takes over the loan under lender requirements | Approval terms and whether the original borrower is released |
Ask about the seller's remaining liability
For a VA loan, assumption approval, release of liability, and restoration of the veteran's entitlement are distinct questions.
Have the servicer explain each one for the proposed transfer.
A release of liability does not by itself restore entitlement.
Request answers before choosing a structure
Ask who owns the home after closing, who owes each lender, and who can demand repayment.
Request the payment schedule, insurance arrangements, and the process for missed payments in writing.
Have your own attorney review the documents, including what happens if a promised refinance fails.
Compare the arrangement with a sale that pays off the existing mortgage.
A lower payment can come with continuing obligations that matter more to your decision.
