How to structure a Subject-To deal, in five steps
A Subject-To deal is not closed with charm. It is closed by one number — the gap between what the seller owes and what you agreed to pay — and by a closing package that protects the seller's credit and your ownership. Here is the sequence, in the order real leads are run.

Most advice about Subject-To deals starts with the pitch, and that is exactly backwards. A Subject-To is a specific financial fact: the seller’s existing mortgage stays in place and you take title subject to it. Whether that fact is a good deal for you is decided before anyone mentions creative finance. Run the five steps in order and the structure either assembles itself or the lead was never a Subject-To — and if you want the wider test against Seller Finance, Wholesale and a Cash Offer, that is the one-question comparison.
Step 1: start from the loan, not the house
Before you look at the kitchen, get five facts about the mortgage: the payoff balance, the interest rate, the monthly payment (principal, interest, taxes and insurance — the whole PITIA, not the principal and interest line), whether the payments are current, and who the lender is. The payoff figure comes from the seller’s latest statement or a payoff request; the rest they usually know from memory.
Two of those facts carry more weight than the rest. The rate is what you are actually buying: a 3.1 percent loan inherited in 2026 is an asset no lender will write today, and the wider the gap to current rates, the more valuable the structure. The arrears matter to the seller conversation: a seller behind by three payments needs the arrears reinstated at closing, and that number comes out of your cash to close. Also ask whether the loan is FHA or VA — those are assumable with lender approval, which is a different and even better deal than Subject-To, and worth knowing before you price anything.
Step 2: run the equity test
Subject-To rewards low equity, which is the opposite of what most investors instinctively look for. The arithmetic is one subtraction: your agreed price minus the loan balance is the cash you owe the seller at closing. On a $330,000 house with $310,000 owed, you pay the seller roughly $20,000 and the inherited loan carries the deal. On the same house with $40,000 owed, the same structure means finding $290,000 in cash — and the cheap loan you were preserving is now a rounding error. Below roughly 20 percent equity, the structure starts to make sense; below 10 percent, it is usually the best deal on the table for both sides.
The test: cash to seller = agreed price − loan balance. Small number, real deal. Big number, different Structure.
Step 3: make the existing payment service the deal
A Subject-To with no spread is a liability wearing a profit costume. The rent the property earns has to cover the full inherited payment — taxes and insurance included — plus maintenance, plus a vacancy reserve, and still leave cash flow worth holding. If the inherited payment is $1,900 and the rent is $2,050, you are working for the seller’s lender at your own risk. If the payment is $1,350 and the rent is $2,050, the loan itself is the profit.
Do this before the offer, not after closing, because it caps what you can pay the seller. If you already have the four numbers in front of you, the creative finance deal calculator applies exactly these rules to what you type and shows the monthly cash flow and cash-on-cash return beside the Structure.
Step 4: the seller conversation, in the open
The Subject-To conversation has one thing every other structure does not: the seller stays on their loan. That fact has to be said on the first call, plainly, and it is usually the thing that either closes the seller or ends the conversation — both are fine outcomes. Explain it the way it works: their name stays on the note, the payment keeps being made on time through a servicing company they can check, and their credit is serviced rather than damaged.
What you get in exchange for that honesty is the seller who has no better option: they are relocating and would carry two mortgages, they are behind on payments, they inherited a house with a loan on it. What you must not do is let the words “take over the payments” blur into “the loan goes away”. Every ugly Subject-To story you have heard is a concealment story, and the fix costs one clear sentence.
Step 5: the closing package
A Subject-To closing is a normal closing with four additions. One: a title company that has done one before — this is not exotic, but the closer should confirm the loan stays open and the deed records correctly. Two: the deed goes into a land trust, which keeps the seller’s name off the public transfer and keeps your options open for a later sale or refinance. Three: insurance rewritten to the trust, with the lender’s interest preserved — a policy still written to the seller is how a claim gets denied. Four: the servicing company set up before the first payment is due, so there is a history from month one.
That package is also your due-on-sale posture. The transfer gives the lender the contractual right to call the balance; the honest answer to that risk is not a trick but a plan — the payment history, the insurance in order, and the exits mapped out in advance. The mechanism, how often lenders actually enforce, and the three exits from a called loan are all in the due-on-sale guide.
What this looks like on a live lead
The five steps compress into two questions you ask the seller — what they owe or pay monthly, and why they are selling — because those are the two things public data cannot tell you. Everything else, the value, the comps, the rent, the equity gap, is sitting in the address. That is exactly how Propwise runs: you enter the address, answer the two questions, and it names the Structure, the Runner-up, the terms it would offer and the one thing it did not know that you should ask about.

Questions investors ask
How much cash do I need to structure a Subject-To deal?
The cash to the seller is the agreed price minus the loan balance you are taking over, plus closing costs and enough reserves to carry the payment while you stabilise the property. That is why low equity is what makes a Subject-To work: on a $330,000 house with $310,000 owed, you might close with a few thousand dollars instead of a bank-sized down payment. On a house with $40,000 owed, the same structure means handing the seller $290,000 in cash, and at that point the cheap inherited loan is a rounding error and you are just buying a house.
Do I need the lender's permission to take a house Subject-To?
No, and there is no application to make. Taking title Subject-To does not involve the lender at all — the loan stays in the seller's name and the note is not assumed. What the lender holds is the due-on-sale right: the contractual option to call the balance if the property transfers. That is the seller's contract, it is a civil matter rather than a crime, and the honest structure is one where the seller understands exactly what stays on their credit. The mechanics of that clause are in the due-on-sale guide.
Should the property go in a land trust?
Most Subject-To investors close into one, and the reason is privacy and resale, not concealment. A trust keeps the seller's name off the recorded deed, which makes it easier to sell or refinance later without explaining the transfer at the county recorder's office. Be clear with yourself about what it does not do: it does not hide the transfer from the lender, and it does not remove the due-on-sale right. The other thing that must match is insurance — a policy written to the seller's name on a house your trust owns is a claim waiting to be denied.
How do I make sure the mortgage payment actually gets paid?
Third-party servicing, from day one. You pay a loan servicing company a small monthly fee; they collect from you and remit to the lender, and both you and the seller can log in and see the history. This matters for three reasons: the paper trail is what reassures the seller that their credit is safe, it removes the temptation to skip a month during a vacancy, and it protects you from the seller who changes their mind and claims you never paid. Never pay the lender directly by hand and never let the statement go to a house you do not check.
What happens to the seller's credit in a Subject-To deal?
Their name stays on the note, so the loan keeps reporting on their credit file — which is why the deal has to be built so the payment is never late. Handled properly, the seller's credit actually improves while you pay, and many sellers use that as part of the conversation: they walk away with their debt serviced and their credit repaired. Handled badly — one missed payment, or a transfer they did not understand — you have damaged a person's credit on a house they no longer own. Say all of this out loud on the first call, and put it in the disclosure.
How do I know a Subject-To deal works before I make the offer?
Four numbers, in order: what it is worth, what they owe, at what rate, and what it rents for. Low balance against value means little cash to close; a rate well under today's means the financing itself is the profit; and the rent has to cover the existing payment plus taxes, insurance and reserves with room left over, or there is no deal to structure. If you have an address, Propwise runs that sequence and names the Structure in under a minute — two Verdicts are free. If you already hold the four numbers, the calculator applies the same rules to what you type.
