Definition
Subject-to
A real estate transaction where the buyer takes title to a property while leaving the existing mortgage in the seller's name. The buyer contractually agrees to keep making the mortgage payments.
Subject-to in plain English#
A subject-to transaction is one where a buyer takes title to a property while leaving the existing mortgage in the seller's name. The buyer becomes the legal owner. The seller's mortgage is still on the lender's records — but the buyer has contractually agreed to make every payment.
The seller no longer owns the property but remains legally liable for the loan until the buyer either pays it off, refinances, or sells.
Why anyone would do this#
For sellers, subject-to solves a specific problem: getting out from under the mortgage payment when traditional sale, cash offer, or modification don't work. Common scenarios — behind on payments with no equity, low-rate loan worth preserving, or divorce situations where one party needs out fast.
For buyers (typically real estate investors), subject-to acquires property without needing to qualify for new financing — useful when rates are high or when speed matters.
The due-on-sale clause issue#
Almost every modern mortgage contains a due-on-sale clause giving the lender the right to demand full loan payoff if title transfers without their consent. In subject-to, that transfer technically triggers the clause.
In practice, lenders rarely call loans due when payments are on time — they have no financial incentive. The risk increases meaningfully if payments are missed or if interest rates rise dramatically above the existing loan's rate. Real, but historically small in our experience.
Seller protections that matter#
The seller is taking real risk in a subject-to: the mortgage stays on their credit, and if the buyer stops paying, the seller's name catches the foreclosure. A properly structured NJ subject-to includes:
- Third-party loan servicing so the seller sees monthly payment confirmation
- An acceleration clause returning title to the seller if the buyer defaults
- Insurance with the seller as additional insured
- A fixed refinance deadline forcing the buyer to take the loan into their own name within 3–5 years
