A wrap loan is a form of seller financing in which the seller keeps their existing mortgage in place and issues the buyer a new, larger loan that “wraps around” the original debt. The buyer makes one monthly payment to the seller. The seller uses part of that payment to keep the original mortgage current and keeps the rest. The structure lets buyers purchase without a bank and lets sellers earn the spread between the low rate on their original loan and the higher rate they charge the buyer. It also carries real legal exposure, mostly from the due-on-sale clause in nearly every conventional mortgage and from federal rules that restrict how sellers can structure the financing.
How the Structure Works
The defining feature is that the seller’s original mortgage stays active after the sale closes. The seller does not pay it off. Instead, the seller signs a new promissory note with the buyer at a higher interest rate, covering the remaining balance on the original mortgage plus the seller’s equity, minus the buyer’s down payment. That new note is secured by a deed of trust or mortgage on the property, creating a junior lien that sits behind the original lender’s first lien.
A concrete example makes the math clear. The seller owes $120,000 on the original mortgage at 3.5%. The parties agree on a $200,000 sale with a $30,000 down payment. The seller writes a wraparound note for $170,000 at 6.5%. Each month the buyer pays the seller based on the $170,000 note. The seller forwards enough to the original lender to cover the $120,000 loan’s monthly obligation and keeps the difference.
The seller’s return comes from two places. The seller earns 6.5% on the full $170,000 note while paying only 3.5% on the $120,000 that still sits underneath. The seller also collects principal payments that gradually pay down both notes. That three-point spread on someone else’s debt balance is where wrap loans earn their reputation as high-yield deals.
Why Buyers Agree to Wrap Loans
The main draw is access. A seller acting as lender can accept a lower credit score and lighter paperwork than a bank will. Self-employed borrowers, buyers recovering from foreclosure or bankruptcy, and people with non-traditional income are the usual candidates. When conventional lenders say no, a wrap loan may be the only way in short of waiting years to rebuild credit.
Closing costs generally run lower because the deal skips several bank-required charges such as origination fees and lender-mandated appraisals. Savings vary by deal, but buyers often avoid several thousand dollars in upfront costs.
The rate on the wrap note is negotiable. In some markets a buyer can land a rate below what banks are quoting, most likely when the seller’s underlying loan carries a very low rate that leaves room for a competitive wrap rate and a healthy spread. Most wrap rates, though, sit at or near market because the seller wants the full return.
One tax point catches buyers off guard. A wraparound mortgage counts as “secured debt” for the home mortgage interest deduction only if the deed of trust or mortgage is recorded or otherwise perfected under state law.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction The IRS uses a wraparound mortgage as its example of a debt that fails the secured-debt test when the security instrument is not recorded. If the seller refuses to record the wrap deed (to keep the underlying lender in the dark), the buyer cannot deduct any of the interest paid. For many buyers that loss wipes out much of the financial appeal of the arrangement.
Why Sellers Offer Them
The financial pull for sellers is the spread. A seller carrying a 3.5% mortgage who writes a wrap at 6.5% earns three points on the underlying balance plus the full 6.5% on the equity portion of the note. The sale becomes a high-yield investment secured by the property the seller just handed over.
Sellers who use the installment method under IRC Section 453 can spread capital gains tax over the life of the note instead of recognizing the entire gain in the year of sale.2Office of the Law Revision Counsel. 26 US Code 453 – Installment Method Installment treatment is the default for qualifying sales where at least one payment arrives after the tax year of the sale.3eCFR. 26 CFR 15a.453-1 – Installment Method Reporting for Sales of Real Property and Casual Sales of Personal Property Sellers report installment income annually on Form 6252.4Internal Revenue Service. About Form 6252, Installment Sale Income For a seller sitting on a large gain, the deferral alone can justify the complexity.
Attractive financing terms also give the seller room on price. A buyer who can’t qualify for a bank loan is less likely to argue price with the only lender willing to work with them.
The Due-on-Sale Problem
Nearly every conventional mortgage contains a due-on-sale clause allowing the lender to demand full repayment when the borrower transfers any interest in the property. The Garn-St. Germain Depository Institutions Act of 1982 gives lenders broad federal authority to enforce these clauses and preempts state laws that might restrict them.5Office of the Law Revision Counsel. 12 US Code 1701j-3 – Preemption of Due-on-Sale Prohibitions
A wrap loan transfers a property interest in a way that almost always violates the original mortgage. Recording the wraparound deed of trust creates a public record the lender can find. Once the lender knows and chooses to enforce, the seller typically has 30 days to pay the entire remaining balance. If the seller cannot, the property moves toward foreclosure.
The buyer takes the hardest hit. The original lender’s first lien has priority. If that lender forecloses, the buyer’s junior lien is wiped out along with any equity and down payment. The buyer’s only recourse is a breach-of-contract claim against the seller, which is slow, expensive, and may recover nothing if the seller is broke.
Exemptions That Don’t Cover Wrap Loans
Garn-St. Germain lists nine categories of transfers that lenders cannot use to trigger the due-on-sale clause, including transfers on the borrower’s death, transfers to a spouse or children, transfers from divorce, transfers into a living trust where the borrower stays a beneficiary, and the creation of a subordinate lien that does not involve a transfer of occupancy rights.6GovInfo. 12 US Code 1701j-3 None of them protect a wrap loan. A wrap is an arm’s-length sale with a new occupant, which is exactly what the clause is designed to catch.
The subordinate-lien exemption sometimes confuses people. It covers a lien “which does not relate to a transfer of rights of occupancy.” A home equity line fits because the same borrower still lives there. A wrap loan does not, because the entire point is to put someone else in the property.
The “Silent Wrap” Bet
Some sellers try to hide the transaction by not recording the deed of trust, leaving the original hazard insurance in place, and continuing to make payments as if nothing changed. This delays detection but does not eliminate risk. Lenders can find the transfer through property tax records showing a new mailing address, changes in insurance, mismatches in Form 1098 reporting, or a routine loan-file audit. The lender’s right to accelerate lasts for the entire life of the underlying loan. A silent wrap is a bet on lender inaction across 15 or 30 years, and the bet can lose at any point during that window.
Federal Rules Limiting How Sellers Can Structure a Wrap
The Dodd-Frank Act layered another set of rules on top of the due-on-sale problem. Under Regulation Z, anyone who offers and negotiates residential mortgage loan terms is generally a loan originator and must be licensed. Sellers financing their own property sales can sidestep that requirement only inside two narrow exemptions:
- One property in any 12-month period. A natural person, estate, or trust financing a single sale is exempt. The loan cannot have negative amortization, and any interest rate must be fixed or adjustable only after five or more years with reasonable caps.7eCFR. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
- Three or fewer properties in any 12-month period. Available to any person including a business entity, but the financing must be fully amortizing, the seller must make a good-faith determination that the buyer can repay, and the rate must be fixed or adjustable only after five or more years.7eCFR. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
The practical effect is significant. A seller financing more than three sales in a year needs a mortgage loan originator license. The three-property exemption’s “fully amortizing” requirement effectively bans balloon payments, which used to be standard in seller financing. Sellers who built their approach around a five-year balloon on a 30-year amortization schedule cannot use that structure inside the three-property exemption. State law adds another layer on top, so consulting a real estate attorney familiar with seller financing in your state is worth the fee.
Tax Consequences on Both Sides
The Buyer’s Interest Deduction
A buyer paying interest on a wrap loan can deduct it like any other mortgage interest, but only if the wraparound deed of trust is recorded or otherwise perfected under state law. Publication 936 uses a wraparound mortgage as its example of a debt that fails the secured-debt test when the security instrument is not recorded, in which case none of the interest is deductible.1Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction
That creates the central tension in most wrap deals. Recording protects the buyer’s lien priority and preserves the deduction, but it creates the public record most likely to trigger the due-on-sale clause. Not recording keeps things quiet, but the buyer loses the deduction and stands on weaker legal ground if anything goes wrong. Both sides need to see the tradeoff clearly before closing.
The Seller’s Installment Sale Reporting
Under the installment method, only the profit portion of each payment received is taxable in the year received. Sellers who want to recognize the whole gain up front (to use capital losses in the same year, for instance) can elect out. Sellers receiving $600 or more in mortgage interest during the year in the course of a trade or business must file Form 1098 reporting the interest received.8Internal Revenue Service. Instructions for Form 1098 Using a professional loan servicer makes this reporting cleaner for both parties.
Structuring the Deal to Reduce Risk
A wrap requires two core documents. The wraparound promissory note sets out the buyer’s repayment obligation: principal, rate, payment schedule, maturity, and what counts as default. The wraparound deed of trust or mortgage secures the note against the property.
The written agreement should reference the original loan’s balance, rate, payment amount, and remaining term. The buyer needs to know exactly what underlying debt they are layering on top of. It should also specify who pays property taxes and insurance, whether those items are escrowed, and how changes in those costs are handled.
Third-Party Loan Servicing
Using a neutral third-party servicer to collect and distribute payments is the single most important protection in a wrap deal. The buyer pays the servicer, who forwards the correct amount to the original lender and remits the rest to the seller. That eliminates the risk that the seller pockets the payment and skips the underlying mortgage. That scenario is the nightmare case in wrap loans and it happens more often than either party expects.
A servicer also keeps payment records, handles escrow for taxes and insurance, and issues year-end tax documents. Fees for private mortgage note servicing typically run $20 to $45 per month depending on loan size and whether impound services are included. The agreement should require the servicer to notify the buyer immediately if the underlying loan payment goes unpaid.
Hazard Insurance
Insurance needs to protect both the buyer’s and the seller’s interests, which is harder than it looks. The original lender is usually named as a loss payee on the existing policy. If the buyer opens a new policy in their own name and the old one is cancelled, the lender will notice and may force-place expensive coverage or investigate. If the old policy stays in place but the named insured is no longer the occupant, a future claim can be denied for misrepresentation. Getting this right generally means working with an insurance agent who understands seller-financed transactions.
Protections the Buyer Should Insist On
Because the buyer carries the most risk, the contract should give the buyer specific rights:
- Monthly proof that the underlying mortgage payment was made. A servicer handles this automatically, and the contract should still require it.
- The right to pay the original lender directly if the seller ever misses a payment, and to deduct that amount from what the buyer owes the seller.
- A defined outcome if the original lender accelerates the loan under the due-on-sale clause. Options include giving the buyer time to refinance, requiring the seller to pay off the underlying loan, or letting the buyer rescind.
- Immediate notice of any default, missed payment, or communication from the original lender.
What Happens When Someone Defaults
If the Buyer Stops Paying
The seller’s remedy depends on how the transaction was structured and on state law. With a deed of trust, the seller as beneficiary can start foreclosure. Most states require a notice-and-cure period before the sale, and judicial foreclosure states can extend the process well past a year. Throughout, the seller must keep paying the original mortgage or face a separate foreclosure from the first lien holder.
If the Seller Stops Paying the Underlying Loan
This is the scenario that makes wrap loans genuinely dangerous for buyers. The buyer can make every payment on time and still lose the property because the seller failed to forward the money. The original lender does not care about the wrap and will foreclose on its first lien, wiping out the buyer’s position.
A buyer who discovers this has narrow options. A direct-payment clause in the contract lets the buyer start paying the original lender directly. Breach-of-contract claims against the seller are available but slow and often uncollectible. This is why third-party servicing is not optional in a wrap loan. It is the one reliable way to make sure the underlying mortgage actually gets paid.
When a Wrap Loan Is Worth Considering
Wrap loans work best under a narrow set of conditions. The seller’s underlying mortgage carries a low rate and no prepayment penalty. The buyer cannot qualify for conventional financing but has a credible plan to refinance within a few years. Both parties hire separate attorneys. A professional servicer handles all payment flows. When those conditions hold, the deal creates a genuine win on both sides.
Outside those conditions the risks stack up quickly. A buyer who cannot refinance before a balloon comes due, a seller who commingles buyer payments with personal funds, or either party who skips the attorney review is heading toward an outcome much worse than the deal simply falling through. The spread that makes wrap loans attractive is compensation for real risk, and both sides need to price that risk honestly before signing.
