Selling Subject-To: The Honest Seller's Guide

A subject-to sale means you deed the house to a buyer who takes over your existing mortgage payments, while the loan itself stays in your name. It can rescue a sale when you have little equity or face foreclosure. It also carries real risks, and any buyer who will not explain them is not a buyer you should work with.
Best for: Little or no equity, behind on payments, or facing foreclosure with a good loan worth keeping alive.
How does a subject-to sale actually work?
You transfer the deed to the buyer, but your mortgage stays in place and in your name. The buyer takes over the monthly payments, brings the loan current if you are behind, and typically maintains, rents, or resells the property. Ownership changes. The loan does not.
Subject-to exists because of a gap in how real estate works: deeds and loans are separate legal objects. The deed says who owns the house. The loan says who owes the bank. A subject-to purchase transfers the first without touching the second. For a seller with 5 percent equity and 2 months of missed payments, this can be the difference between a foreclosure on your record and a clean exit, because there is no requirement to pay the loan off at closing.
What are the risks to me as the seller?
Three real ones. The loan stays on your credit, so a buyer who stops paying damages you. The lender can call the loan due under the due-on-sale clause. And your name stays tied to a property you no longer control. Every one of these deserves a written protection in the agreement.
Here is what most creative buyers will not volunteer. Nearly every mortgage has a due-on-sale clause, which lets the lender demand full payoff when the property transfers. Lenders rarely call performing loans, but rarely is not never. Your protections should be in writing: proof of every payment to you or a third-party servicer, a deed-back or performance clause if the buyer defaults, and full disclosure signed by both sides. We put all three in our agreements because we would demand the same in your chair.
When does subject-to beat a cash offer?
When the math beats it. A cash offer must clear your loan payoff, so low equity means low or negative cash to you. A subject-to offer is not limited by payoff math, so it can be thousands higher, stop a foreclosure faster, and preserve your credit while the loan gets paid on time every month.
Say your house is worth 700,000 dollars and you owe 660,000. A cash offer at a fair investor price leaves you nothing, or worse, requires you to bring money to closing. A subject-to buyer can pay you for your equity position, take over the 660,000 loan, and make the payments. Every on-time payment after that actually helps the credit history attached to that loan. This is exactly the kind of trade-off we show you in writing, next to a plain cash offer, so you choose with real numbers.
What paperwork should a seller expect at a subject-to closing?
Five documents, minimum: the purchase agreement naming the loan and responsibilities, a recorded deed through a title company, a third-party servicing agreement you can monitor, a signed disclosure that both sides understand the due-on-sale clause, and a written default remedy. A kitchen-table deed signing with none of these is how horror stories start.
The paperwork is the difference between a legitimate subject-to transaction and an expensive lesson. Escrow and title make the transfer clean and insurable. The servicing agreement gives you a live window into every payment on a loan that still carries your name. The default remedy, often a deed-back provision, defines your worst day in advance. Bring the stack to a real estate attorney before signing. A buyer with nothing to hide will encourage exactly that.
Questions sellers ask us
Is subject-to legal?
Yes. Buying and selling subject to an existing loan is legal and appears in standard California purchase contract language. The due-on-sale clause makes it a lender's contractual option to call the loan, not a prohibition on the sale. Have your own attorney review any agreement. We encourage it.
Will this hurt my ability to buy my next home?
The mortgage still shows as your debt until it is paid off or refinanced, which can affect your debt-to-income ratio. Some lenders will offset it with 12 months of proof that someone else pays it. Plan this with your next lender before you commit, and we will provide the documentation trail.
What happens if the buyer stops paying?
With us, the agreement says you get notified immediately and have written remedies, including taking the property back. That is also why payments run through a neutral third-party servicer you can check anytime. Any subject-to buyer who resists a servicer is telling you something. Listen to that.
