The Due on Sale Clause, Explained in Plain English
The due on sale clause is the one sentence in a mortgage that every subject-to investor knows by heart.
And most of them would really prefer you didn’t read it.
Here’s the short version. Almost every home loan says the lender can demand the full balance if the house is sold or transferred without its OK.
That’s it. One line. It’s the reason a “no money down” house can turn into a “please wire $240,000 by Friday” house.
So let’s read it together, in plain English, before you buy anything built on top of it.

What is a due on sale clause?
It’s a term in your mortgage contract.
The gist: if you sell or transfer the property, the lender gets the option to say “the whole loan is due now.”
Not the next payment. The whole thing.
Lenders like it because it lets them reprice. Say the seller locked a 3% rate years ago. The bank would love that loan gone when rates are higher. The clause is their exit.
Here’s the part people skip: it’s an option, not an alarm. Nothing explodes automatically. The lender may call the loan. It doesn’t have to.
Why does it matter for subject-to?
Subject-to is the strategy SubTo teaches. In SubTo’s own words, it’s “buying a property and leaving the seller’s existing mortgage where it is: you take title by deed, the loan stays in the seller’s name, and you take over the payments.”
Read that again slowly.
You take the deed. The loan stays behind. That’s a transfer. That’s exactly the thing the clause is about.
So every subject-to deal sits on top of a mortgage that, on paper, the lender has the right to call.
To SubTo’s credit, it says this out loud. Its how-it-works page lists the risk that a lender calls the due-on-sale clause, right next to a line I genuinely like: “No money down doesn’t mean no money.”
Fair. Now let’s look at the law itself.
The law: Garn-St Germain, 12 U.S.C. §1701j-3
The federal rule comes from the Garn-St Germain Depository Institutions Act of 1982. The relevant part lives at 12 U.S.C. §1701j-3, and you can read the whole thing free on Cornell’s site.
The key sentence says that notwithstanding any state constitution or law to the contrary, a lender may enter into or enforce a contract with a due-on-sale clause.
Translation: federal law backs the bank. Your state can’t wave the clause away.
But Congress also carved out a list of transfers where the lender is not allowed to call the loan.
Which transfers are exempt from the due on sale clause?
Subsection (d) covers loans on residential property with fewer than five dwelling units (plus co-op units and residential manufactured homes). For those, the lender may not call the loan because of:
- A junior lien. A second lien or other encumbrance that ranks below the lender’s and doesn’t transfer the right to live there.
- An appliance loan. A purchase-money security interest for household appliances. Your financed fridge is safe.
- A joint tenant’s death. A transfer by will, inheritance or operation of law when a joint tenant (or tenant by the entirety) dies.
- A short lease. A lease of three years or less with no option to purchase.
- A borrower’s death. A transfer to a relative because the borrower died.
- Spouse or children. A transfer where the borrower’s spouse or children become an owner.
- Divorce. A transfer from a divorce decree, legal separation agreement or property settlement that makes the spouse an owner.
- A living trust. A transfer into an inter vivos trust where the borrower is and remains a beneficiary, and that doesn’t transfer the right to occupy the property.
- Anything regulators add. Any other transfer described in regulations from the Federal Home Loan Bank Board.
Notice anything missing?
A sale to an unrelated investor is not on the list.
Not “investor who means well.” Not “investor who paid $9,800 for a course.” Not “investor with a really nice spreadsheet.” It’s just not there.
That’s the whole ballgame for subject-to. The exemptions protect families, heirs, divorces and estate planning. They don’t protect a stranger taking the deed.
Can the bank call the loan on a subject-to deal?
Yes. It may.
Will it? Nobody can tell you for sure, and you should be skeptical of anyone who acts like they can.
Here’s how I’d think about it.
It’s a contract right, not a crime
Breaking a due-on-sale clause isn’t illegal. Nobody’s getting arrested over it.
It’s a contract issue between the borrower (the seller, remember, not you) and the lender. The lender’s remedy is calling the loan.
Subject-to itself is legal. I go deeper on that in is subject-to legal?.
“May” means the lender decides, not you
This is the part that bugs me.
The whole deal depends on a decision made by someone who isn’t in the deal. The bank doesn’t attend your closing. It doesn’t care about your exit strategy. It just has a right, and it can use it when it wants.
It’s like building your house on your neighbor’s driveway because he said he “probably won’t” park there.
I’m not a lawyer, and this isn’t legal advice. Talk to a real estate attorney in your state before you sign anything.
What happens if the bank calls the loan?
The balance comes due. Then somebody has to come up with it.
Realistically, that leaves a short menu:
- Pay it off in cash. If you have a spare few hundred grand lying around, you probably weren’t shopping for no-money-down deals.
- Refinance into your own loan. At today’s rate, on your own credit, and only if you qualify.
- Sell the property. Hopefully for more than the balance, after costs.
And if none of that happens? The loan is still in the seller’s name. Missed payments and a foreclosure would show up on their credit, not yours. That’s the part sellers find out too late. More on that in subject-to risks nobody mentions.
Run the numbers: what a called loan does to cash flow
Here’s a calculator. The defaults are a made-up but typical example: a seller’s old loan with a $1,300 principal-and-interest payment, $350 a month in taxes and insurance, $2,300 in rent, a $240,000 balance, and a 7% rate if you had to refinance. It also counts the $9,800 SubTo charges to learn the strategy.
Subject-to deal calculator (with the "bank calls the loan" stress test)
The defaults are a made-up but typical example. Swap in your own numbers to see what the deal looks like if the bank calls the loan.
With those defaults, the deal cash-flows about $121 a month on the seller’s loan.
That’s about 81 months, almost seven years, just to earn back what you paid to learn it.
Now hit the stress test. If the bank calls the loan and you refinance $240,000 at 7%, your payment jumps to about $1,947 with taxes and insurance. Cash flow goes to roughly negative $176 a month.
You’d be paying for the privilege of owning a house that a stranger’s old loan used to make work.
Change the numbers. Maybe your deal is better. But run the called-loan line every time.
How do subject-to investors handle the due on sale clause?
The honest answer: mostly by accepting the risk and planning an exit.
The common ideas you’ll hear are keeping payments perfectly on time, keeping reserves, and having a plan to refinance or sell if the loan gets called. SubTo, per its site, offers deal reviews, document review and “experts on call from offer to close.”
That’s all reasonable. None of it removes the clause.
You’re managing a risk, not eliminating it. Reserves mean you can survive the call. They don’t mean the call won’t come.
Which is why I always ask: what does all of this cost before you even get to the risk? The SubTo cost and refund page has the official $9,800 number and the checkout fine print. And if you want the bigger picture on the program itself, here’s my full Pace Morby review and my SubTo review.
The bottom line on the due on sale clause
Let me be fair about this.
Subject-to is legal. Pace Morby really does deals. The clause is a risk, not a death sentence, and plenty of loans never get called.
But “plenty never get called” isn’t a business plan. It’s a weather forecast.
Every subject-to deal you’ll ever do sits on a loan in a stranger’s name, governed by a clause that federal law lets the lender enforce, with an exemption list that doesn’t include you.
Me? I’d rather own real estate that has no loan to call.
The stuff I own now is websites. Little sites that rank on Google for things like “tree service in [city],” then get rented to a local business that wants the phone calls. No mortgage. No seller. No title company. No due-on-sale clause, because there’s no sale and no loan.
You found this page on Google. That’s the proof the model works.

Q&A
- Q: What is a due on sale clause?
- A: A line in most mortgages that lets the lender demand the whole remaining balance if the property is sold or transferred without its permission. It's an option the lender has, not an automatic trigger.
- Q: Is it illegal to violate a due on sale clause?
- A: No. It's a contract term, not a criminal law. Breaking it gives the lender the right to call the loan. It doesn't send anybody to jail. More in is subject-to legal?
- Q: What federal law covers due on sale clauses?
- A: The Garn-St Germain Depository Institutions Act of 1982, at 12 U.S.C. §1701j-3. It lets lenders enforce the clause even where state law says otherwise, with a list of exemptions.
- Q: Does selling to an investor trigger the due on sale clause?
- A: It can. A sale to an unrelated investor isn't on the federal exemption list, so the lender keeps its right to call the loan.
- Q: Can I put my house in a living trust without triggering it?
- A: The statute exempts a transfer into an inter vivos (living) trust where the borrower is and remains a beneficiary, for homes with fewer than five units. Ask an estate attorney how that applies to you.
- Q: Will the bank definitely call the loan?
- A: Nobody can promise that either way. The law says the lender may. Whether it does is up to the lender, and you don't get a vote.
- Q: What happens if the bank calls a subject-to loan?
- A: Someone has to pay off the balance, usually by refinancing at today's rates or selling. If nobody does, the seller's loan can head toward foreclosure. Run the numbers in the calculator on this page.
- Q: Can I just not tell the bank?
- A: That's the strategy, more or less. It's also why I'd rather own an asset where the whole plan isn't "hope the lender doesn't look up."
- Q: Is the due on sale clause the same as a prepayment penalty?
- A: No. A prepayment penalty charges you for paying early. A due-on-sale clause lets the lender demand you pay everything now. One's a fee, the other's an eviction notice for your loan.
- Q: So what would you do instead of a subject-to deal?
- A: Own the kind of real estate that has no mortgage at all, so there's no clause to worry about. I rent out websites to local businesses. Watch this video and thank me later.
