What a Wraparound Mortgage Is — and How the Spread Works

A wraparound mortgage — sometimes called an all-inclusive trust deed (AITD) in western states — is a form of seller financing where the seller does not pay off their existing mortgage when they sell. Instead, they carry a new, larger note to the buyer that wraps around the existing debt. The seller collects payments from the buyer at the new interest rate, then continues making payments to the underlying lender at the original rate.

The spread between the two rates is profit for the seller. If the existing loan carries a 3.5% interest rate and the seller wraps the new note at 7%, the seller earns the 3.5% spread on the original principal balance. On a $200,000 underlying loan, that spread generates meaningful passive income every month — on top of any cash they receive at closing.

For investors, wraparound mortgages solve a different problem: they provide a path to acquire a property with existing below-market financing without triggering a due-on-sale clause through a formal assumption. The buyer takes subject-to the underlying mortgage as part of a fully documented wraparound structure, with the seller's attorney crafting the note and security instrument to reflect the wrapped terms.

Joette Trinh has structured wraparound transactions across Connecticut and Massachusetts. She understands the mechanics from the inside — how to build the wrap so it protects the seller's security interest, how to give the buyer enforceable rights, and how to document the transaction so there's no ambiguity about who is responsible for what.

The wraparound note must be drafted carefully. It sets out the purchase price, the interest rate, the monthly payment, the balloon date, and the buyer's rights to prepay. The underlying loan details are disclosed in full — not because disclosure is always legally required, but because hidden encumbrances create problems that surface at the worst possible moment. Joette builds clean documents from the start so neither party has a surprise three years into the deal.

Connecticut and Massachusetts both recognize seller financing structures including wraparounds. The regulatory considerations differ slightly by state — CT has specific usury caps and disclosure requirements; MA has its own consumer protection frameworks that can apply to residential transactions. Joette's dual-state practice means she knows which rules apply to which transaction.

Consultant oversight is not optional on a wraparound. The existing lender's note almost certainly contains a due-on-sale clause. The legal risk of a technical default must be assessed. The buyer's rights in the event of seller default on the underlying must be documented. Escrow procedures for the monthly pass-through must be clear. These are not template problems — they require analysis of the specific deal, the specific existing loan, and the specific state law.
