Seller financing vs subject-to: what's the difference?
Last updated 2026-07-17
In seller financing, the seller owns the property free and clear and carries a new note for the buyer. In a subject-to deal, the buyer takes over payments on the seller's existing mortgage, which stays in the seller's name. Seller financing suits high-equity sellers; subject-to targets low-equity or distressed sellers.
Two structures, opposite sellers
The creative-finance world often lumps these together, but they serve opposite situations. Subject-to exists because the seller has little equity and an attractive existing loan: the buyer steps into the payments and the debt stays in the seller's name. Seller carry exists because the seller has full equity and no debt: they can be the bank on a brand-new note with terms both sides choose.
That difference drives everything else: risk, legality, seller motivation, and which owners to even approach.
The comparison
Due-on-sale risk: subject-to deals transfer ownership while the old mortgage remains, which nearly always violates the loan's due-on-sale clause; the lender can call the loan. Seller carry has no existing loan, so there is nothing to call.
Seller profile: subject-to fits distress (pre-foreclosure, job loss, low equity). Seller carry fits success (long ownership, paid-off property, a landlord ready to retire from tenants but not from income).
Paper: subject-to leaves the seller liable on debt for a property they no longer own. Seller carry gives the seller a secured note and first lien position, the same position a bank holds.
History: seller carry is the proven half. In the early 1980s, when bank rates hit the high teens, a large share of home sales closed with owner financing. High-rate environments always revive it.
Frequently asked questions
Is subject-to legal?
Transferring a deed subject to an existing mortgage is generally legal, but it almost always breaches the loan's due-on-sale clause, giving the lender the right to demand full payoff. The structure carries real risk for both parties, especially the seller who remains liable on the debt.
Which is safer for the seller?
Seller financing. The seller holds a secured note and a first lien on a property they no longer manage. In subject-to, the seller stays personally liable on a mortgage they no longer control.
Why do investors prefer seller financing at high rates?
The note rate is negotiated between the parties rather than set by a bank, terms are flexible, and there is no lender underwriting timeline. When bank money is expensive, a negotiated seller note often beats it.
