A subject-to deal in real estate is a purchase where the buyer takes title to the property but leaves the seller’s existing mortgage in place, in the seller’s name, and continues making payments on it. The deed changes hands. The loan does not. The buyer becomes the legal owner at the county recorder’s office, while the seller remains personally liable to the bank for a debt secured by a house they no longer own. That split is the entire appeal and the entire risk.
How the Ownership and Loan Split Works
At closing, the seller signs a deed transferring title to the buyer, and that deed gets recorded. The buyer now owns the property. The original promissory note stays exactly where it was: in the seller’s name, on the seller’s credit report, enforceable against the seller if payments stop.
The buyer’s obligation to pay comes from a private agreement with the seller, not from any contract with the lender. The lender doesn’t approve the deal and, in most cases, doesn’t know it happened. If the buyer walks, the lender pursues the seller on the note, because the seller is the one who signed it.
That separation is what makes the structure attractive on both sides. A buyer picks up a loan at whatever rate the seller locked in, which can be years below current market rates and can turn a thin rental deal into a working one. A seller who needs out fast — behind on payments, relocating, divorcing, carrying a house they can’t sell at a price that clears the loan — gets immediate relief without waiting for a traditional buyer to qualify. Neither side gets what a conventional closing gives them: a clean break for the seller and a direct relationship with the lender for the buyer.
The Due-On-Sale Clause
Nearly every residential mortgage contains a due-on-sale clause. Federal regulations define it as a contract provision allowing the lender to declare the entire remaining balance immediately due and payable when the property is sold or transferred without the lender’s written consent.1eCFR. 12 CFR Part 191 – Preemption of State Due-on-Sale Laws Recording a new deed is the kind of transfer that triggers it.
If the lender calls the loan, the full balance becomes due at once. If it isn’t paid, the lender can foreclose. The buyer loses the property and whatever money went into it. The seller takes a foreclosure on their credit and possible liability for any deficiency.
How Often Lenders Actually Call the Loan
Having the right and using it are different things. Foreclosure is expensive, and a lender watching a loan where every payment arrives on time has little reason to disturb it. Acceleration on a performing loan is uncommon in practice, but the decision belongs entirely to the lender and the buyer has no legal right to prevent it.
Interest rates shape the risk. If the seller locked in a 3.5% rate and current rates are above 6%, the lender has a reason to call the loan and redeploy the capital at today’s rate. If the loan rate is close to market, the lender has almost no reason to look. That math can shift, and so can a servicer’s internal policy or the result of a routine audit that flags the ownership transfer.
The Garn-St. Germain Trust Workaround
The Garn-St. Germain Depository Institutions Act of 1982 lists specific transfers on residential properties with fewer than five units where lenders cannot enforce the due-on-sale clause. These include transfers to a spouse or children, transfers resulting from divorce, transfers after a borrower’s death, and transfers into a living trust where the borrower remains a beneficiary and occupancy doesn’t change.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions
Investors often try to use the trust exemption by having the seller first transfer the property into a land trust (a protected transfer), then later changing the beneficiary to the buyer. The theory is that the second step isn’t a title transfer at all. Whether it holds up depends on the lender. The statute requires the original borrower to remain a beneficiary, and federal regulations add that the borrower should remain an occupant.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions A lender that looks and finds the original borrower is neither has a strong argument that the exemption doesn’t apply.
What the Seller Is Really Taking On
The mortgage stays on the seller’s credit report and counts against the seller’s debt-to-income ratio for as long as it exists. Sellers often don’t think this through until they try to buy their next house and find that a loan they thought they’d walked away from is still blocking them.
Fannie Mae underwriting guidelines allow a lender to exclude that mortgage from the seller’s debt-to-income ratio, but only if the person actually making the payments is obligated on the mortgage debt, there have been no late payments in the most recent 12 months, and the seller isn’t using rental income from that property to qualify.3Fannie Mae. Monthly Debt Obligations The seller needs 12 months of canceled checks or bank statements from the buyer to prove consistent payment. USDA loan guidelines apply a similar 12-month rule for debts transferred without a release of liability.4U.S. Department of Agriculture. HB-1-3555, Chapter 11 – Ratio Analysis
The practical effect: during the first year after closing, a seller almost certainly cannot qualify for a new mortgage at competitive terms, because the subject-to loan still inflates their debt ratio. After 12 months, the exclusion depends on clean documentation. A single late payment by the buyer in that window wipes out the DTI relief. That is why the servicing arrangement matters so much to the seller — not just for getting paid, but for preserving the paper trail that eventually frees them to borrow again.
What the Buyer Is Really Taking On
Insurance is where these deals quietly fall apart. The seller’s homeowner’s policy names the seller as insured. Once title transfers, that policy no longer matches ownership, and most insurers will cancel it when they learn of the change. The buyer needs a new policy bound before or at closing, with the existing mortgage lender named as loss payee, because the loan documents require it. For a rental, that means a landlord policy rather than a standard homeowner’s policy.
Timing is everything. Any gap in coverage shows up to the lender through the escrow account and can prompt either a force-placed policy or a closer look at the loan, either of which can lead to the due-on-sale clause being triggered. A claim filed against a policy whose named insured no longer owns the property can be denied outright.
Federal Equity Skimming Liability
Buying properties subject-to and then collecting rent without making the mortgage payments is a federal crime when the loans are insured by HUD or guaranteed by the Department of Veterans Affairs. The equity skimming statute reaches anyone who purchases one-to-four-unit dwellings with a federally insured or VA-guaranteed loan in default, or that goes into default within a year of purchase, fails to make the mortgage payments, and diverts rental income for personal use. The penalty is a fine of up to $250,000, up to five years in prison, or both.5Office of the Law Revision Counsel. 12 USC 1709-2 – Equity Skimming; Penalty; Persons Liable; One Dwelling Exemption
The statute exempts a buyer who purchases only one such property, so it targets investors running a pattern rather than a one-time buyer who falls behind. It applies regardless of whether the buyer is formally obligated on the loan; the “whether or not the purchaser is obligated on the loan” language was written with these deals in mind.5Office of the Law Revision Counsel. 12 USC 1709-2 – Equity Skimming; Penalty; Persons Liable; One Dwelling Exemption For buyers taking FHA or VA properties this way, payment discipline is not optional.
The Documents That Make It Enforceable
A subject-to closing requires several documents that work together. Missing any of them leaves one side or both exposed.
The deed transfers legal title and gets recorded at the county recorder’s office. A special warranty deed is common, with the seller guaranteeing clear title only against defects that arose during their ownership, not against earlier problems.
A promissory note between buyer and seller, separate from the one the seller signed with the bank, documents the buyer’s promise to make the mortgage payments and spells out what happens on default. Without it, the seller has no written recourse if the buyer walks. The note typically mirrors the existing loan’s schedule and balance and should give the seller real remedies, such as the right to reclaim the property through a deed held in escrow or a privately recorded deed of trust.
A servicing agreement sets up how payments flow. The most protective version uses an independent third-party loan servicer that collects from the buyer, remits to the original lender, and sends monthly statements to both parties. The seller gets verification without having to trust the buyer’s word; the buyer gets a documented payment history that will later matter for both the seller’s DTI relief and any refinance.
A limited power of attorney from the seller lets the buyer deal with the lender on insurance updates, escrow questions, payoff requests, and payment issues, since the lender will only speak to the borrower of record. The scope should stay narrow: account inquiries and insurance, not loan modifications or new borrowing against the property.
Because no new financing is being originated, the transaction doesn’t require the Closing Disclosure that accompanies conventional mortgage originations.6Consumer Financial Protection Bureau. What Is a HUD-1 Settlement Statement? Closings commonly use a modified HUD-1 settlement statement, which itemizes the purchase price, the existing loan balance being taken subject-to, and prorations for taxes and insurance.7HUD. Fill-able HUD-1 Settlement Statement Line 203 on that form is labeled “Existing loan(s) taken subject to,” which is why it remains the standard.
Planning the Exit
A subject-to deal doesn’t end at closing. The seller’s name stays on the loan until something retires it. Most buyers plan to refinance into their own name within a few years, sell the property at a profit that pays off the original loan, or hold it until the loan is paid down. Each path shortens or extends the seller’s credit exposure.
Before signing, the seller should know how long their name is expected to stay on the loan and what triggers the buyer’s obligation to refinance them out. A well-drafted promissory note sets a deadline by which the buyer must either refinance or return the property. Without one, the seller has agreed to carry a liability on an open-ended timeline, which is the version of this deal that ends badly.
