What Is a Wraparound Mortgage?

Published 2026-09-09 Last reviewed 2026-09-09 By Lisa C Hamilton, REALTOR®

Quick Answer

A wraparound mortgage is a seller-financing arrangement in which the seller provides financing to the buyer while an existing underlying mortgage remains in place. The buyer generally pays the seller under the new wraparound obligation, and the seller remains responsible for paying the underlying lender. Because title may transfer while the original lender's loan remains outstanding, wraparounds can create substantial due-on-sale, servicing, default and legal risks.

How Does the Math Work?

Seller's existing mortgage

$250,000 at 3%

Sale price

$500,000

Buyer down payment

$100,000

Seller creates wraparound financing

$400,000

The buyer pays the seller according to the $400,000 wrap. The seller continues making payments on the underlying $250,000 mortgage. The spread between the two obligations may create income for the seller.

Why Would Seller Do This?

Potential reasons: earn interest, expand the buyer pool, create income, or sell a property with low existing financing.

Why Would Buyer Do This?

Potential reasons: the buyer cannot obtain traditional financing, the negotiated terms are attractive, or the existing low-rate debt indirectly supports the economics.

Major Risk: Due-on-Sale

Transfer of ownership can trigger the existing lender's due-on-sale rights unless an exception applies.

“Seller is still making the payment”

does not mean

“Lender has no right to accelerate.”

Federal law generally permits enforcement of due-on-sale clauses outside specified exceptions.

Major Risk: Buyer Pays Seller, Seller Doesn't Pay Bank

Imagine the buyer faithfully pays $3,000 each month, but the seller stops paying the underlying mortgage. The underlying lender forecloses.

The buyer can face devastating consequences. That is why third-party servicing and controls are so important.

Major Risk: Underlying Loan Changes

If the underlying loan is an ARM, the payment can change. If escrow rises, the seller's required payment changes. The wraparound agreement needs to address these realities.

This Needs Attorneys

A wraparound should not be created from a downloadable template.

Frequently Asked Questions

Is wraparound the same as subject-to?

Related but different. In a wrap, seller typically creates a new financing obligation to buyer while underlying loan remains.

Does lender know?

That depends on structure and communications, but due-on-sale rights cannot simply be ignored.

Can wraparound be used if seller owns property free and clear?

If there is no underlying mortgage, there is nothing to 'wrap'; that becomes ordinary seller financing.

A wraparound should never be created from a downloaded template.
