Wrap-around Mortgage
Wrap-around Mortgage is a financing concept describing a form of capital or debt structure used to fund M&A acquisitions.
Full Definition
A wrap-around mortgage (also called an all-inclusive trust deed or AITD) is a seller-financed second mortgage that incorporates and wraps around an existing first mortgage on the property. The buyer makes a single payment to the seller at a blended interest rate; the seller continues making payments on the underlying first mortgage (which is not paid off or assumed) and pockets the spread between the blended rate and the first mortgage rate. The buyer does not directly interact with the original lender — all payments flow through the seller.
In SMB M&A, wrap-around mortgages most commonly appear in real estate-intensive business acquisitions where the underlying property carries an existing mortgage with favorable terms (especially pre-2022 low-rate loans). Rather than requiring the buyer to obtain new financing at higher current rates, the seller wraps the existing mortgage into seller-provided financing, allowing the buyer to benefit from the embedded low-rate debt indirectly.
For example: a seller has a property with a $500K first mortgage at 4% interest (an old SBA-financed loan). A buyer wants to acquire the property-and-business package. Rather than the buyer taking a new $800K loan at 8%, the seller provides an $800K wrap-around mortgage at 6.5%. The buyer pays 6.5% on $800K; the seller uses $500K of that payment to service the existing 4% first mortgage and earns the 2.5% spread on the first $500K plus 6.5% on the incremental $300K.
Wrap-around mortgages carry legal risk: most commercial mortgages contain due-on-sale clauses that require the full mortgage to be paid upon any transfer of the underlying property. A wrap-around that does not satisfy the due-on-sale clause by paying off the first mortgage may technically trigger a lender default — the original lender can accelerate the entire first mortgage balance. Sellers and buyers pursuing wrap-around structures need experienced real estate counsel to navigate due-on-sale exposure.
Seller vs. Buyer Perspective
A wrap-around mortgage lets you earn a favorable spread on the existing low-rate mortgage while providing seller financing to close a deal at a higher blended price. The risks: you remain on the hook for the underlying first mortgage — if the buyer stops making payments to you, you must continue paying the bank or face foreclosure. Ensure you have robust default remedies (acceleration rights, personal guarantee, right to cure and take possession) built into the wrap-around agreement.
A wrap-around lets you benefit from the seller's embedded low-rate debt without refinancing at current market rates — potentially saving significant annual interest cost. However, you are making payments to the seller, not directly to the bank, which introduces intermediary risk: if the seller stops making payments to the underlying lender (using your payments for other purposes), the property could be foreclosed despite your own timely payments. Consider a managed escrow or a direct payment arrangement to the underlying lender to mitigate this risk.
Real-World Example
A buyer acquired a storage facility business including the real property. The seller had a $1.2M SBA first mortgage at 3.5% (originated in 2020). Rather than refinancing at current 8% rates, the parties structured a $2M wrap-around mortgage at 6.25% — $800K of new seller financing wrapped around the existing $1.2M first mortgage. The buyer paid $125K per year to the seller; the seller paid $42K per year on the original SBA loan and kept the $83K spread. Net seller financing cost to the buyer: significantly below what a conventional 8% new loan would have cost.
Why It Matters & Common Pitfalls
- !Due-on-sale clause acceleration. Most commercial mortgages include due-on-sale provisions. A wrap-around that does not pay off the first mortgage technically violates this clause, giving the original lender the right to accelerate the full balance. Obtain written lender consent or payoff before structuring a wrap-around.
- !Seller default on underlying mortgage. If the seller misappropriates the buyer's payments and fails to service the underlying mortgage, the property faces foreclosure even if the buyer is current. Mitigate by escrowing the first mortgage payments through a third party or paying the bank directly.
- !Title complexity. Wrap-around mortgages must be carefully documented — recorded correctly, coordinated with title insurance, and disclosed to all lenders. Improperly documented wraps create title defects that affect future refinancing or sale.
- !Regulatory constraints on SBA loans. SBA loans carry specific restrictions on assumptions and transfers. A wrap-around on an SBA-financed property may violate SBA program rules — obtain SBA approval or a legal opinion before proceeding.
