Mortgage contract provision that lets the lender demand payoff when ownership changes without approved loan transfer.
A due-on-sale clause is a mortgage contract provision that lets the lender demand full repayment if the property is sold or transferred without lender-approved treatment of the existing loan.
Due-on-sale clauses matter because they control whether an existing mortgage can stay in place after a transfer. They are one of the main reasons Assumption of Mortgage and Subject to Mortgage carry very different risk profiles.
If title changes hands, the lender reviews whether the transfer is allowed under the loan documents and applicable law. If the transfer is not protected by an exception and the lender does not approve an assumption, the lender may accelerate the loan and require payoff.
| Transfer structure | What happens to title | Lender risk under due-on-sale clause |
| — | — | — |
| Approved assumption | Title transfers and buyer is approved on the debt | Lower, because lender consents to the new borrower |
| Subject-to transaction | Title transfers without full approved debt transfer | Higher, because lender may call the loan |
| Ordinary sale with payoff | Title transfers and old loan is repaid | Clause is satisfied because debt is paid off |
The clause is related to acceleration, but it is more specific. It is triggered by transfer of ownership rather than by missed payments or another ordinary default.
A homeowner sells a property to a buyer who wants to keep the old low-rate mortgage in place. The buyer takes title without completing a formal assumption. If the mortgage contains a due-on-sale clause and the lender objects, the lender can demand immediate payoff even if the monthly payments are still being made.
An Acceleration Clause can be triggered by several kinds of default. A due-on-sale clause is the transfer-specific version tied to ownership change.
Actual enforceability depends on the contract, the loan type, and the governing legal exceptions. The practical question is whether the transfer is one the lender can challenge and whether the lender chooses to do so.
