Wraparound Mortgage 2026: Mechanics, Legal Risk, and When MLOs See This Structure

A wraparound mortgage is a seller-financed instrument where the seller extends a new note to the buyer that includes the outstanding balance on the existing underlying mortgage. The seller continues paying the underlying mortgage while the buyer makes payments on the larger wraparound note. The seller earns a spread between the rate on the underlying loan and the rate charged on the wraparound.

Example Structure

• ✦Seller has a $200,000 balance at 3.5% on the existing mortgage
• ✦Seller extends a $300,000 wraparound note to the buyer at 6%
• ✦Buyer pays the seller on the $300,000 note each month
• ✦Seller uses those payments to service the underlying $200,000 mortgage
• ✦Seller earns the rate differential on the wrapped portion and the full return on the equity portion

Legal and Compliance Risks

The primary risk is the due-on-sale clause in the underlying mortgage. If the lender discovers the title transfer and accelerates the loan, the seller must pay off the underlying mortgage immediately, which can collapse the wraparound arrangement. If the seller fails to make payments on the underlying mortgage, the buyer's collateral is at risk even if the buyer is current on the wraparound note. SAFE Act and Dodd-Frank ability-to-repay rules apply to the seller acting as a lender on the wraparound. Some states have specific recording and disclosure requirements for wraparound transactions.

When MLOs Encounter Wraparound Structures

• ✦Investor-to-investor sales where the seller has favorable underlying financing to monetize
• ✦Rising rate environments where the underlying rate is significantly below current market rates
• ✦Properties with assumable loans where the seller wants to capture profit on the rate spread
• ✦Installment sale structures where the seller wants to defer capital gains treatment over time
