"Subject to financing" and "subject to mortgage" both describe a transaction where the buyer takes ownership of a property while an existing loan stays in place. The key is that the loan itself is not paid off or replaced at closing. Instead, the buyer purchases the property subject to that existing mortgage.
In a classic subject to deal:
This is different from a formal loan assumption. With a true assumption, the lender reviews and approves the buyer, then formally transfers responsibility for the mortgage to that buyer. In a subject to arrangement, the lender typically is not a direct party to that understanding between buyer and seller, so the original borrower (the seller) remains liable to the lender.
Because of this structure, the mechanics of a subject to transaction usually include:
The term "subject to mortgage" is often used interchangeably with "subject to financing" in this context. Both focus on the same core idea: the buyer takes title to the property without paying off or refinancing the existing loan, and that existing loan continues under the seller's name.
Subject to financing can be very attractive, but it is not a fit for every situation. Understanding both the upside and the tradeoffs is critical before you use it.
Subject to financing most often makes sense when:
Because subject to financing shifts risk without formally changing the underlying loan, careful structure and discipline matter more than in a standard sale. A few practical steps can help protect everyone involved.
Subject to financing and subject to mortgage arrangements can solve real problems and unlock opportunities when used carefully. The key is to treat them as sophisticated transactions that require clear agreements, aligned expectations, and professional input, not as a shortcut around sound financial and legal planning.
