Subject-To Financing in Real Estate: What MLOs Need to Know

Subject-to financing involves purchasing a property while the existing mortgage remains in place and the seller stays on the note. The buyer takes title and makes payments on the existing loan without formally assuming it. MLOs typically encounter subject-to transactions when a seller proposes them as an alternative to a conventional sale, or when an investor buyer is structuring a creative acquisition.

The Due-on-Sale Clause

Virtually every conventional mortgage originated since the early 1980s includes an acceleration clause that allows the lender to demand full repayment if the property is transferred without their consent. This is commonly called the due-on-sale clause. A subject-to transaction triggers this clause because title transfers to the buyer while the existing loan does not formally transfer. In practice, lenders rarely call loans current on subject-to transfers, but the risk exists and is real.

Why Borrowers Pursue Subject-To

• ✦Sellers with below-market rate mortgages can offer buyers effectively subsidized financing without refinancing
• ✦Buyers avoid the need to qualify for a new loan, which benefits those with credit challenges
• ✦Closing costs are lower because there is no origination or title insurance on a new loan
• ✦Investors use subject-to as an acquisition strategy in high-rate environments to preserve low-rate existing debt

What MLOs Should Understand

MLOs are not typically involved in originating subject-to transactions because no new mortgage is being originated. However, MLOs may encounter them when a listing discloses an existing assumable mortgage, or when a client describes a prior purchase that was done subject-to and asks whether it can be refinanced. The existing loan must be paid off in a cash-out refinance, and the seller of record (who may not be the occupant) must participate in the transaction.

Formal Assumptions vs. Subject-To

A formal assumption involves the lender's written consent and typically a credit qualification of the buyer. VA loans are assumable with lender approval, and FHA loans originated before a certain date were also assumable. Subject-to transactions have no lender approval, which distinguishes them from a formal assumption. MLOs helping clients navigate properties with existing low-rate mortgages should understand both paths.
