Subject-To Real Estate: How It Works, and What You Owe the Seller
Buying subject-to (subto) in real estate means you take title to a property while the seller's existing mortgage stays open, and you take over making the payments.
No underwriting
No appraisal
I have closed many of these. I have also watched people get hurt by them, and almost every time the damage traced back to the same thing: the buyer treated a subto as a trick for getting a house cheap instead of what it really is: a financing structure built on somebody else's credit.
I teach a lot of classes, and I'm known for this saying:
"It's cool to do deals with no money out of pocket. It's unethical to do deals with no money in your pocket."
^ Especially when someone else's credit is on the line.
^ Even if you're not buying subto, you need cash reserves. It's irresponsible to the point of negligence, and therefore, it's unethical to do these deals with no money in your pocket.
^ That means you can't be using all your available cash just to close...
👏 HAVE 👏 SOME 👏 RESERVES people!
So let's get a good understanding of what's going on so you can make sure your own deals are safe, legal, and ethical.
What Does Buying Subject-To Real Estate Mean?
The full phrase is "subject to existing lien(s)." Basically, the house comes with baggage from a previous relationship. The loan is not assumed or paid off, so the seller stays legally liable on the debt while the buyer holds title and makes the payments.
A loan assumption is different: The lender evaluates and approves the new borrower, their planned use of the property, and may approve the loan assumption, which releases current borrower from the debt. A subto gets you the rate without the release, and the release is the part that protects the seller.
So the seller is handing you their credit, with no mechanism to take it back if you stop performing. This is what I call a "naked subto," and I much prefer a wraparound mortgage closing, because that gives sellers the right to foreclose for nonpayment. This article is only about subto, but you can read more about wraps here.
How Does a Subject-To Purchase Work, Step by Step?
A subto closing runs through 6 stages.
Agree to price. Total price = current loan balance + cash to seller. There can be other items in that formula (add solar & water softener liens, judgments, catching up arrears on the loan, or even some seller finance in the mix).
Agree to terms. Terms may include mandatory payoff date (balloon), allowed use of the property, rights to reclaim the house, the amount of cash reserves required, who makes the payments to the mortgage company, etc.
Now get the contract signed! Don't forget the subto disclosures... That's where the seller acknowledges they understand the nature of the transaction and that their credit is tied to your performance.
Open Escrow. If you're in Colorado or Tennessee, send your signed contract to [email protected]. Otherwise, select a title company that's familiar with subto transactions (not all title companies will close them, and some won't tell you that until days before closing when they suddenly realize what they've said yes to).
Verify the loan. Get a current mortgage statement and confirm the balance, rate, escrow balance and payment status yourself.
Pro Tip: To avoid getting tricked by an edited PDF (yes, I've seen this happen), check the online mortgage portal on a screenshare so you can see the balance/status live.Prepare documents, close & record. Sign the deed, disclosures, debt, new insurance, limited power of attorney, and any additional special terms. Docs and dollars flow through escrow (your title company), and the deed gets recorded.
Take over servicing. Update the auto-pay on the mortgage portal and make sure to manually schedule the first one. (Don't mess it up like I did once!)
Why Do Sellers Ever Agree to This?
Sellers agree because a subto solves a problem that a conventional sale cannot. Relocation, divorce, a property that will not appraise for what is owed, or a rental they are done managing. In each case, the seller needs the payment off their plate faster than a listing can deliver, and at a higher price than a cash buyer will pay.
For a seller already behind, a buyer who brings the loan current can be the difference between a foreclosure and a usable credit score.
It is also the reason the ethics matter more here than in a cash purchase. A seller in that position is not negotiating from strength, and the gap between what they understand and what they signed is where the worst people play games.
Put the disclosure in writing, in plain language, and make sure they can repeat it back to you.
(At Creative Title, if a seller can't explain the nature of their own subto transaction, we won't close it. Our mission is to bring stewardship to real estate transactions.)
What Does the Due-on-Sale Clause Really Do?
Every conventional mortgage has a due-on-sale clause, which gives the lender the right to call the full balance due if the property transfers without consent. A subto transfer triggers that condition. Anybody telling you an investor purchase is immune to the due on sale clause is lying or ignorant (or both).
What is genuinely uncertain is whether the lender will enforce the due on sale clause. Lenders have had little reason to disturb a performing loan, but "has not so far" is a different claim from "cannot." The acceleration timeline, the right to cure and what the mail looks like when a lender moves are all covered in my other article: What Happens When a Lender Calls the Due-On-Sale Clause (which is the one piece of reading I wouldn't skip before closing a subto).
A land trust does not actually prevent due on sale, I don't care what your mentor, TC, or YouTube told you. The risk comes with the deal, so if the heat's too high, stay out of the kitchen.
If a due on sale letter ever does arrive, remediation is its own skillset: our sister company does that work directly through Creative TC's due-on-sale remediation.
What Are the Risks the Courses Skip?
The due-on-sale clause gets all the airtime because it is dramatic and easy to teach. The real risks that cost investors money are quieter: insurance written wrong, no cash reserves, the payment gap after closing.
Insurance written wrong. A policy naming only the seller can produce a denied claim. The new owner's interest belongs on the policy and the lender still belongs on it as mortgagee.
No reserves. Escrow shortages, tax increases and a furnace all arrive on somebody's timeline and not yours. A subto with no cash behind it is a seller's credit file waiting to be damaged.
The payment gap at closing. Servicing does not transfer on the day you close and new autopay takes weeks to activate, which is exactly how the first payment gets missed.
No exit. Have a plan in case the deal doesn't work the way you planned. If it doesn't cash flow, are you OK eating the monthly loss (sometimes it's OK if you have a longer-term play in mind). Also, have a plan for how the loan comes off the seller's name eventually; that could be a refinance, a sale, or by letting the loan run its full course.
A wrap is a subto with better accountability controls. Creative TC laid out the difference between a subto and a wrap better than I could restate it here. (Oh yeah, I wrote that article too... 😉)
PRO TIP: Write the seller a plain-English summary of what stays in their name, what happens to their credit if you miss a payment, and how the loan eventually comes off. If you can't write that page comfortably, you are not ready to close the deal.
How Do These Files Close Cleanly?
Plenty of title companies will not touch a subto, and the reason is rarely legality. Underwriter appetite and internal policy differ at every company, so the same contract gets declined in one office and closed as routine work in another. Finding that out during closing week makes it tough for you to look competent, and is an expensive way to learn that lesson.
Creative finance closings are core competencies at Creative Title, rather than an exception we accommodate. The underwriting relationship and the staff experience are already built around subto files.
There are deals we turn down. It's not that they're complicated or messy; those are just part of the job work. It's the ones that will only close if the seller never fully understands what they signed up for. That's an easy no for me. One thing I'm really good at is standing on principle.
The Takeaway
Subto is a financing structure, not a loophole for accountability. It works when the loan is verified, the seller understands what it means for the loan to stay in their name, and the buyer holds enough reserves to never miss a payment.
Do it that way and it is one of the most useful tools in real estate. Do it another way and become some Attorney General's case study.
