A wrap-around mortgage is a seller-financed instrument in which the seller extends a new note to the buyer that “wraps around” an existing senior lien. The seller retains the underlying loan obligation, collects a single payment from the buyer, and services both debts from that payment — making professional third-party servicing a structural necessity, not an option.

Key Takeaways

• A wrap mortgage is two notes in one transaction: the seller’s existing senior lien and the new wrap note issued to the buyer.
• The seller — now the “wrap lender” — remains personally obligated on the underlying loan while collecting payments from the buyer.
• TILA (Reg Z), RESPA (Reg X), state usury laws, and the due-on-sale clause in the senior note all govern wrap transactions simultaneously.
• Third-party servicers track, allocate, and document every payment across both obligations — a function that self-servicing wrap lenders routinely fail to perform correctly.
• Wrap notes carry legal exposure that materializes the moment a payment is misallocated, a disclosure is omitted, or the underlying lender enforces its due-on-sale clause.

Wrap Mortgage: The Formal Definition

A wrap-around mortgage — also called a wrap loan, all-inclusive deed of trust (AITD), or all-inclusive mortgage — is a form of seller financing in which the seller conveys title (or a contract for deed) to a buyer and simultaneously extends a new promissory note for an amount that equals or exceeds the outstanding balance on the seller’s existing senior mortgage. The wrap note states a new interest rate, payment schedule, and maturity date. The underlying senior lien is not paid off at closing. Instead, it remains in place, and the seller-turned-lender uses the buyer’s monthly payment to fund the senior lender’s required payment before retaining any spread.

The defining characteristic: the buyer’s obligation (the wrap note) wraps around — and is legally subordinate to — a senior lien the buyer never signed. That asymmetry creates the servicing complexity and the legal risk. For a full analysis of how wrap structures function in practice, see The Mechanics of Wrap-Around Mortgages.

The Two-Note Structure That Defines a Wrap

Every wrap transaction produces exactly two promissory notes that must be tracked and serviced independently:

The underlying senior note. This is the original mortgage the seller obtained from a conventional lender, a private lender, or another seller-financer. Its balance, interest rate, payment amount, maturity date, and covenant package — including the due-on-sale clause — remain unchanged. The seller continues to be the named borrower on this instrument. Non-payment triggers the senior lender’s right to foreclose, regardless of whether the buyer is current on the wrap note.

The wrap note. This is the new seller-financed instrument the buyer signs. Its principal balance equals the purchase price minus the buyer’s down payment — which, in a pure wrap, means the face amount of the wrap note exceeds the balance of the underlying senior note by the seller’s equity. The wrap note carries its own interest rate (usually above the underlying rate, creating a yield spread for the seller), its own payment schedule, and its own security instrument recorded against the property.

Professional servicers — including Note Servicing Center — maintain separate ledgers for both obligations, produce payment histories for both, and document the allocation of every dollar received from the buyer across the two instruments. Servicers who treat a wrap as a single note create accounting defects that surface in default and litigation.

Who Holds the Underlying Senior Note in a Wrap?

The seller holds — and remains personally obligated on — the underlying senior note. That obligation does not transfer to the buyer at closing. The buyer’s payment to the seller funds the senior lender’s payment, but the senior lender’s contractual relationship is exclusively with the original borrower: the seller.

This structure creates a dual-principal problem. The buyer’s credit risk falls on the wrap lender (the seller). The senior lender’s credit risk still falls on the original borrower (the seller). If the buyer stops paying the wrap note, the seller must continue paying the senior lender or face foreclosure from above. A third-party servicer provides the audit trail that proves timely payments were made to the senior lender — documentation the seller needs in any enforcement action against the non-paying buyer.

For private lenders acquiring wrap notes from sellers in the secondary market, verifying the payment history on the underlying senior note is an underwriting requirement, not a best practice. That history lives with whoever is servicing the transaction.

Why a Wrap Is Not a Standard Subordinate Note

A subordinate note — a second mortgage or deed of trust — sits behind a senior lien that the borrower is separately obligated to pay. The subordinate lender has no involvement in the senior payment: the borrower writes two checks, to two lenders, from one bank account.

A wrap note inverts that relationship. The wrap lender — not the buyer — writes the check to the senior lender. The buyer writes one check to the wrap lender. This means:

• The wrap lender bears the payment-forwarding obligation and the timing risk. If the buyer pays on the 10th and the senior lender requires payment by the 1st, the wrap lender must front the gap.
• The wrap lender is a pass-through for the senior payment, making servicing records the only defensible evidence that the senior obligation was met.
• Any yield spread the wrap lender earns on the interest-rate differential is income earned by performing a payment-forwarding function — a function regulators scrutinize under TILA and state usury statutes.

A subordinate note carries none of these obligations. That distinction determines which compliance frameworks apply and which servicing protocols are required. See Legal Risks of Wrap Mortgages for a full breakdown of how courts and regulators treat this distinction.

The Servicing Obligations Embedded in the Wrap Structure

The two-note structure generates servicing requirements that exceed those of any single-lien private note:

Payment receipt and allocation. The servicer receives the buyer’s payment, posts it to the wrap note ledger, forwards the required amount to the senior lender on or before the senior note’s due date, and retains or remits the seller’s net spread. Each step requires a dated, time-stamped record.

Escrow management (when applicable). If the senior lender requires escrow for taxes and insurance — a requirement embedded in most conventional loan agreements — the servicer must maintain an escrow analysis for the senior loan, track impound balances, and ensure the senior escrow is funded. If the wrap note also requires the buyer to impound taxes and insurance (a separate escrow), the servicer runs two escrow accounts on one property. 12 CFR §1024.17 (Reg X) governs escrow account practices on federally related transactions.

Default management. A buyer default on the wrap note triggers different remedies than a default on the senior note. The servicer must issue default notices that satisfy the wrap note’s terms and any applicable state foreclosure statute — while simultaneously ensuring the senior lender’s payment is not disrupted. Servicers who handle only one layer of this process expose both the seller and the buyer to compounded liability.

Legal Frameworks That Govern Wrap Mortgages

Wrap mortgages sit at the intersection of four regulatory regimes, each of which imposes independent disclosure and compliance requirements:

TILA / Reg Z (12 CFR Part 1026). The Truth in Lending Act applies to credit extended for personal, family, or household purposes — and under the Dodd-Frank Act’s mortgage originator provisions, seller-financers who extend more than three seller-financed transactions per year to non-owner-occupants, or any transaction to an owner-occupant, face licensing and disclosure requirements. Wrap lenders who structure residential transactions without TILA-compliant disclosures face rescission rights and statutory damages. See CFPB Reg Z (12 CFR Part 1026).

RESPA / Reg X (12 U.S.C. §2605). The Real Estate Settlement Procedures Act governs servicing transfers and escrow account practices on federally related mortgage loans. When a wrap note is serviced by a third party, the borrower (the buyer) is entitled to servicer disclosures, error resolution procedures, and information request responses under RESPA Section 6. See 12 U.S.C. §2605.

State usury and licensing laws. Every state sets its own interest rate ceilings, seller-financing exemptions, and mortgage broker/lender licensing thresholds. A wrap note carrying a yield spread above state usury limits is void or voidable in most jurisdictions. Texas, California, and Florida each have statutes that address wrap transactions directly.

Due-on-sale clause. Federal law (Garn-St. Germain Depository Institutions Act of 1982) permits federally chartered lenders to enforce due-on-sale clauses upon any transfer of title or beneficial interest. A wrap transaction transfers title or equitable interest to the buyer — an event that activates the clause. Lenders enforce this selectively, but the risk of acceleration of the entire senior balance is real and must be disclosed to the buyer.

Common Terms a Lender Sees in a Wrap Note

Private lenders who purchase wrap notes in the secondary market, or who are evaluating a wrap transaction as an investment, encounter term structures that differ materially from conventional single-lien notes:

• All-inclusive principal balance. The face amount of the wrap note equals the purchase price minus the down payment — not the seller’s equity. The note’s balance exceeds the underlying senior balance by the seller’s equity position.
• Blended interest rate. The wrap note carries a stated rate. The seller’s actual yield is the spread between the wrap rate and the underlying rate, applied to the underlying balance — a function the servicer calculates in every payment allocation.
• Underlying loan reference. Well-drafted wrap notes identify the underlying senior loan by lender, loan number, original balance, rate, and maturity. This reference is the servicer’s starting point for boarding the transaction.
• Payment forwarding covenant. The wrap lender (seller) covenants to forward payments to the senior lender. This covenant is the buyer’s primary protection against an undisclosed default on the senior note.
• Due-on-sale disclosure. Sound wrap notes disclose the existence of the due-on-sale clause in the senior instrument and state who bears the risk of acceleration.
• Default cross-trigger. Some wrap notes provide that a senior lender default — triggered by the wrap lender’s failure to pay the underlying — constitutes a default under the wrap note, permitting the buyer to cure the senior default directly and offset those payments against amounts owed to the wrap lender.

Frequently Asked Questions

Is a wrap mortgage legal in my state?

Wrap mortgages are legal in most U.S. states, but the transaction must satisfy the state’s seller-financing disclosure rules, usury limits, and — in some states — mortgage broker licensing requirements. Texas subjects residential wrap transactions to specific statutory requirements under the Texas Finance Code. California requires compliance with the Holden Act and applicable TILA thresholds. Any wrap structured in a state with an active seller-financing statute requires a transaction attorney, not just a note template.

What is the difference between a wrap mortgage and an AITD?

None — functionally. “All-inclusive deed of trust” (AITD) is the California and western-states term for the same instrument. An AITD is secured by a deed of trust rather than a mortgage. The economic structure — a new note wrapping an existing senior obligation — is identical. The servicing requirements and regulatory exposure are the same regardless of which security instrument the jurisdiction uses.

What happens to the wrap if the senior lender calls the due-on-sale clause?

The senior lender accelerates the entire balance of the underlying loan, making it immediately due and payable. The seller — still named on the senior note — must pay off that balance or face foreclosure. The buyer’s wrap note remains in place as a contractual obligation but is now secured by a property in foreclosure jeopardy. Well-drafted wrap notes include a protocol for this scenario: the buyer is notified, the seller has a cure period, and if the seller fails to cure, the buyer retains the right to pay off the senior lender directly and offset that amount against the wrap note balance.

Does a wrap mortgage require a licensed servicer?

Federal law requires servicers of federally related mortgage loans to comply with RESPA Section 6 (12 U.S.C. §2605), which imposes response timelines, error resolution procedures, and transfer-of-servicing notice requirements. Whether a specific wrap note is a “federally related mortgage loan” depends on the transaction’s characteristics. In states with independent mortgage servicer licensing laws — Texas, Florida, and California among them — third-party servicing of wrap notes requires a servicer license. Self-servicing by the note holder is subject to different licensing thresholds that vary by state.

This guide describes the operational servicing setup for a wrap mortgage. Wrap structures interact with state usury statutes, due-on-sale clauses, and TILA disclosure rules that vary by jurisdiction. Consult qualified legal counsel before originating or accepting a wrap mortgage in any state.
