Subject To
A “subject to” deal means you’re buying a property while the seller’s existing mortgage stays in place — your name goes on the deed, but the old loan keeps ticking under the seller’s name. It’s one of the most creative (and misunderstood) ways to acquire real estate without qualifying for a brand-new mortgage.
How Subject-To Actually Works
In a standard purchase, the seller pays off their mortgage at closing and you get a fresh loan. In a subject-to transaction, the seller’s mortgage doesn’t get paid off. You take ownership of the property, make the monthly payments on the existing loan, and the seller walks away — ideally with some cash or at least relief from a payment they can’t afford.
Say a seller owes $220,000 on a mortgage with a 3.25% rate. Current rates are 7%. By buying subject-to, you inherit that 3.25% payment of roughly $957/month instead of paying $1,350/month on a new loan at today’s rates. That’s $393/month in savings — $4,716 per year.
Why Sellers Agree to This
Most subject-to deals happen when sellers are distressed. They’re behind on payments, facing foreclosure, relocating fast, or upside-down on the property. A subject-to offer solves their problem quickly without the hassle of a traditional sale. They get their name off the deed and stop bleeding money.
Sellers in good financial shape rarely agree to subject-to because they’d rather pay off the mortgage and pocket equity the normal way.
The Due-on-Sale Clause Risk
Here’s the big catch. Nearly every mortgage written after 1982 contains a due-on-sale clause. This gives the lender the right to demand full repayment if ownership transfers. In theory, buying subject-to could trigger this clause and the lender could call the entire loan balance due immediately.
In practice? Lenders rarely enforce it as long as payments keep arriving on time. They’d rather collect interest than deal with foreclosure. But “rarely” isn’t “never.” If the lender does call the loan, you’d need to refinance, pay it off, or risk losing the property.
Watch out for: The seller’s credit is still tied to the loan. If you miss payments, the seller’s credit gets destroyed — and they could sue you. Make sure your agreement spells out exactly who’s responsible for what.
Subject-To vs. Loan Assumption
These get confused constantly. A loan assumption means the lender formally approves you to take over the mortgage. Your name replaces the seller’s on the loan documents. The lender checks your credit, income, and DTI ratio just like a new application.
Subject-to has zero lender involvement. The lender doesn’t know (or at least isn’t formally notified) that ownership changed. That’s what makes it faster — and riskier.
When Subject-To Makes Sense
- Rate arbitrage: The seller’s existing rate is significantly below current market rates
- Low equity deals: The seller owes close to what the home is worth, so there’s not much profit in a traditional sale
- Quick closings: No lender approval means you can close in days, not weeks
- Credit challenges: You can’t qualify for a conventional loan right now but can afford the monthly payment
Most subject-to buyers are investors, not first-time homebuyers. It takes experience to manage the risks properly. If you’re just getting started, a conventional purchase through an FHA or conventional loan is a safer bet.
Frequently Asked Questions
Is buying subject-to legal?
Yes, in all 50 states. It’s not illegal, shady, or a loophole — it’s a standard contract structure. The due-on-sale clause is a lender’s contractual right, not a legal prohibition on the sale itself. That said, you need a real estate attorney to draft the paperwork. Don’t try this with a handshake deal.
How much does a subject-to deal cost?
Closing costs are minimal because there’s no new loan origination. You’ll typically pay $1,500–$3,000 for title transfer, attorney fees, and recording costs — compared to $8,000–$15,000 on a traditional purchase with a new mortgage. Use our closing cost calculator to compare.
