Every wraparound mortgage has the same weak point, and it isn't the interest rate. It's a monthly payment that passes through the seller's hands on its way to a bank that doesn't know the house was sold. Get that one flow of money right, with the right paperwork and a third party in the middle, and a wrap is one of the cleanest creative finance structures there is. Get it wrong and the buyer is one missed seller payment away from a foreclosure they never caused.
This is the complete 2026 guide to wraparound mortgages: what they are, how the payments actually flow, a worked example with real numbers, the due-on-sale question, the Texas rules, the risks on each side, the documents a wrap file needs, and how the closing gets coordinated. It's written for investors and the agents who work with them. If you're a homeowner considering a wrap as a buyer, the risk sections apply to you most.
What is a wraparound mortgage?
A wraparound mortgage (a wrap, or an all-inclusive trust deed in deed-of-trust states) is a form of [seller financing](/blog/seller-financing-real-estate-guide) where the seller keeps their existing mortgage in place and gives the buyer a new, larger loan that "wraps around" it. The buyer makes one monthly payment to the seller on the wrap note. The seller uses part of that payment to keep paying the original lender and keeps the difference. The original loan doesn't get paid off at closing, and the original lender isn't a party to the new deal.
The wrap note is secured by a new deed of trust or mortgage recorded against the property, junior to the original lender's lien. So the property carries two liens: the bank's first, and the seller's wrap behind it. That layering is the whole structure, and it's also the source of every risk in it.
How a wraparound mortgage works, step by step
- 1. The seller has an existing mortgage with a balance, a rate, and a lender, typically a low rate locked in years ago. That loan stays exactly as it is.
- 2. Buyer and seller agree on a price, a down payment, and wrap terms. The wrap note covers the full purchase price minus the down payment, at a rate higher than the underlying loan's rate.
- 3. At closing, the deed transfers to the buyer. Title changes hands. The buyer signs a promissory note to the seller and a deed of trust securing it. The seller's original loan is disclosed in the documents and remains in place.
- 4. Each month the buyer pays the wrap payment to the seller, or, in any well-run wrap, to a third-party loan servicer.
- 5. The servicer pays the underlying lender the original mortgage payment out of the buyer's payment and remits the balance to the seller.
- 6. The wrap is paid off when the buyer refinances, sells, or reaches the balloon date. The underlying loan is paid from the proceeds and the seller gets the rest.
A worked example with real numbers
A seller owns a house worth $300,000 with a aria-hidden="true"80,000 mortgage at 3.25%, a principal-and-interest payment of about $783 a month. A buyer who can't or won't qualify for a 7%+ conventional loan agrees to pay $300,000 with $30,000 down. The seller carries a $270,000 wrap note at 7% amortized over 30 years, with a balloon in year 7.
- Buyer's wrap payment: about aria-hidden="true",796 a month (principal and interest on $270,000 at 7%). - Underlying payment the servicer forwards to the bank: about $783. - Seller keeps: about aria-hidden="true",013 a month.
Look at where the seller's income comes from. They earn 7% on the $90,000 of equity they financed, and they also pocket the 3.75-point spread between 7% and 3.25% on the aria-hidden="true"80,000 the bank is still lending. That spread is why sellers agree to wraps and why investors buy houses this way: the buyer gets a purchase they couldn't finance conventionally, and the seller earns more than a bank would pay them for the same equity. When the buyer refinances in year 7, the underlying loan is paid off from the proceeds and the seller collects the remaining wrap balance.
Wraparound vs. subject-to vs. seller carryback
Three creative finance structures get confused with each other. They are not interchangeable:
| | Wraparound mortgage | [Subject-to](/blog/what-is-subject-to-in-real-estate) | Seller carryback (2nd lien) | |---|---|---|---| | Underlying loan | Stays in place; paid out of the buyer's wrap payment | Stays in place; buyer pays it directly | Paid off at closing by a new first loan | | New note to seller | Yes, for the full price minus down payment | No, or a small one for the seller's equity | Yes, for the gap between the new loan and the price | | Who sends the bank its payment | The servicer, from the wrap payment | The buyer | The new lender is the bank | | Seller's ongoing income | Spread plus interest on equity | Usually none after closing | Interest on the carryback only | | Due-on-sale exposure | Yes | Yes | No |
A wrap is essentially a subject-to deal with a seller-held note wrapped around the underlying loan, which is why the two often show up in the same investor's portfolio. The [all-inclusive trust deed](/glossary/all-inclusive-trust-deed) is the wrap's West Coast name; the mechanics are the same.
The due-on-sale clause: the risk everyone asks about
Nearly every conventional mortgage written since the [Garn-St Germain Act of 1982](https://www.law.cornell.edu/uscode/text/12/1701j-3) contains an enforceable due-on-sale clause: if the property is transferred without the lender's consent, the lender may call the full balance due. A wrap transfers the deed, so the clause is triggered. Full stop. Anyone telling you it isn't is selling something.
What happens in practice is a different question. Lenders rarely call performing loans, especially when the payment arrives on time every month from a servicer. The exposure rises when the loan is in a portfolio being audited, when the insurance policy changes names and the lender's mortgagee clause gets updated, or when rates have moved so far that the lender would rather have the money back. Garn-St Germain also lists specific transfers where the clause can't be enforced (certain transfers into a living trust, to a spouse or child, or on death), and some investors structure around those. The honest position: the risk is real, usually small, and never zero. Both parties should sign a disclosure saying they understand it, and the buyer should have a refinance plan before the balloon date.
Risks for the buyer
- Seller default on the underlying loan. If the seller (or a sloppy servicer) misses the bank payment, the bank forecloses on the first lien, and the buyer loses the house even with a perfect payment record on the wrap. This is the risk that third-party servicing exists to eliminate.
- Undisclosed liens or an inaccurate underlying balance. The buyer is paying on a wrap that assumes a certain underlying balance and rate. If those numbers are wrong, the payoff math at the balloon is wrong.
- Refinance risk at the balloon. A buyer who couldn't qualify conventionally today has to qualify in five or seven years. Credit repair and income documentation should start in year one, not year six.
- Insurance and tax gaps. If the underlying loan had an escrow account and the wrap doesn't replicate it, taxes and insurance can lapse.
Risks for the seller
- Buyer default on the wrap. The seller still owes the bank every month whether or not the buyer pays. A seller with no reserves is one missed payment from a late notice on their own credit.
- Foreclosure cost and time. Foreclosing a wrap deed of trust is a real legal process with real cost, and in judicial foreclosure states it can take a year or more.
- Servicing burden. Statements, escrow, 1098s, payoff demands. Done by hand, this is where sellers make mistakes that turn into disputes. Done by a servicer, it's a line item.
- Regulatory exposure. Federal rules treat some sellers as loan originators once they finance more than a small number of properties in a year; the [CFPB's seller-financer provisions](https://www.consumerfinance.gov/rules-policy/regulations/1026/36/) spell out the thresholds. Sellers doing more than a couple of wraps a year should talk to an attorney about licensing and ability-to-repay requirements.
Texas and state-specific rules
Texas is the biggest wrap market in the country and the most regulated. Since January 1, 2022, [Chapter 159 of the Texas Finance Code](https://statutes.capitol.texas.gov/Docs/FI/htm/FI.159.htm) has required a written wrap disclosure to the buyer at least seven days before closing (listing the underlying loans, their balances, rates, and payment status), required most wrap lenders to be licensed as residential mortgage loan originators unless an exemption applies, and given the buyer specific remedies if the disclosure isn't made. A wrap closed in Texas without the Chapter 159 disclosure is a file that can be unwound.
Other states don't have a wrap-specific statute, but their seller-financing, usury, and foreclosure rules all apply. Deed-of-trust states (Texas, Arizona, California, Colorado, and most of the West) make wraps easier to secure and to foreclose than mortgage states with judicial foreclosure. Whatever the state, the wrap note and security instrument should be drafted by a local real estate attorney, not pulled from a course PDF.
The documents a wraparound file needs
A wrap closing carries the standard purchase paperwork plus a layer that a conventional file never sees:
- Purchase agreement with a seller-financing addendum spelling out the wrap terms and the underlying loan
- Wrap [promissory note](/glossary/promissory-note): price, rate, amortization, balloon, and late-payment terms
- Wraparound deed of trust or all-inclusive trust deed, recorded junior to the existing lien
- Underlying loan disclosure: lender, balance, rate, payment, escrow status, and a recent statement (mandatory in Texas; smart everywhere)
- Due-on-sale acknowledgment signed by both parties
- Authorization to release information, so the buyer and the servicer can verify the underlying loan with the bank
- Third-party servicing agreement naming the servicer, the payment split, and who receives year-end statements
- Insurance: a new policy in the buyer's name with the seller and the underlying lender as loss payees, and confirmation that the underlying lender's mortgagee clause is handled
- Title commitment and an owner's policy for the buyer
- Escrow or closing instructions covering how the underlying loan, taxes, and insurance are handled after closing
Miss the servicing agreement or the release authorization and the wrap can still close. It just can't be verified afterward, which is where disputes start.
Third-party servicing is not optional
Here's our opinion, formed over a lot of wrap files: a wraparound mortgage without a third-party loan servicer is not a financing structure, it's a trust exercise. A servicer receives the buyer's payment, pays the underlying lender, remits the spread to the seller, sends statements to both sides, and keeps the ledger everyone will need at payoff. It costs a small monthly fee. It removes the single biggest risk to the buyer (seller default) and the single biggest administrative burden on the seller. We won't coordinate a wrap without one in the file, and we recommend investors write it into the purchase agreement so the seller can't skip it later.
How a wraparound mortgage closes: the coordination workflow
A wrap is one of the deal types Gold Key TC handles in-house, not farmed out. The workflow our coordinators run on [investor](/investors) wrap files:
- File open, same business day. Contract, addendum, and the underlying loan statement collected up front; if any of the three is missing, that's the first chase.
- Underlying loan verification. Release authorization signed, balance and status confirmed with the lender in writing, escrow status noted.
- Document coordination with the attorney and title. Wrap note, security instrument, disclosures, and in Texas the Chapter 159 disclosure with its seven-day clock tracked on the deadline calendar.
- Servicer setup before closing, with the payment split, first payment date, and statement schedule confirmed so nothing depends on the seller remembering a due date.
- Insurance and title lined up: buyer's policy bound with the right loss payees, title commitment reviewed for anything that would sit ahead of the wrap lien.
- Closing and post-closing. Funding and recording confirmed, recorded documents delivered to both parties and the servicer, and a payoff-planning note in the file for the balloon date.
Wraparound coordination is a flat Wraparound Finance package on our [pricing page](/pricing), with the same refund-in-credits guarantee as every other file: if the deal doesn't close, the fee comes back as credits. Full details are on the [wraparound mortgage coordination page](/services/wraparound-mortgage-coordinator).
When a wraparound is the wrong tool
Don't wrap a loan that's already in default or in forbearance; the due-on-sale question becomes a foreclosure question. Don't wrap when the seller needs cash out today; a wrap pays over time by design. Don't wrap an FHA or VA loan without checking the assumption rules first, because a formal assumption may be cleaner. And don't wrap without a servicer, an attorney-drafted note, and a written exit plan for the balloon. If any of those are missing, a straight subject-to with a small seller carryback, or conventional financing after a credit-repair window, is usually the better deal for everyone.
