A subject-to deal is exactly what it sounds like. The buyer takes ownership of a property subject to the existing mortgage staying in place. The seller's loan does not get paid off at closing. The deed transfers to the buyer, but the loan remains in the seller's name and the buyer takes over the payments. In Nashville and across Tennessee, this structure has become more common as investors look for ways around 7.25 percent investor mortgage rates.
The math is what makes subject-to attractive in 2026. A seller who bought in 2021 has a 3.0 to 3.5 percent fixed rate. An investor borrowing today pays more than double that. If the investor can take over the existing loan, the cash flow works on properties where it would not at current rates. A $340,000 Madison rental at 3.25 percent has a payment under $1,500. The same property at 7.25 percent has a payment over $2,300. That $800 a month is the entire reason subject-to exists.
The legal structure varies by state but the core elements are the same. The seller signs a deed transferring ownership. The buyer signs a performance agreement to make the mortgage payments. Most deals also include a power of attorney, an authorization to release information so the buyer can communicate with the lender, and a structure for handling insurance and escrow. In Tennessee, these documents are recorded with the county register and the deed transfer triggers a transfer tax of $0.37 per $100 of value.
The biggest risk on every subject-to deal is the due-on-sale clause. Almost every conventional mortgage written in the last forty years contains a clause that allows the lender to call the loan due in full if the property transfers ownership. Lenders rarely call the loan as long as payments are current and the buyer's insurance keeps the lender as the loss payee. But the clause exists, and a missed payment, an insurance lapse, or a property tax delinquency can trigger the lender to look at the file and see the transfer.
The second risk is the seller. The seller's name is still on the loan. Their credit takes the hit if the buyer misses a payment. Their debt-to-income ratio still includes the mortgage if they try to qualify for a new house. If the buyer defaults, the seller gets the foreclosure on their record. This is why subject-to deals work best with sellers who do not plan to buy again soon, who are moving for life reasons, or who already have a new mortgage in place.
The third risk is insurance. The existing homeowner's policy has the seller as the named insured and the original lender as loss payee. The buyer needs to add themselves as an additional insured or replace the policy with one that names the buyer as owner. Some lenders flag a policy change to the loan file. Some do not. The cleanest approach is a landlord policy in the buyer's name with a mortgagee clause that names the existing lender. That structure preserves the lender's interest without exposing the deal.
A common entity structure in Tennessee is to set up a land trust. The seller transfers the property into a trust, and the buyer becomes the beneficiary of the trust. The Garn-St. Germain Act of 1982 specifically protects transfers into the seller's own revocable trust from triggering the due-on-sale clause. Whether a beneficial interest assignment after the trust is formed counts as a triggering event is legally murky and depends on the lender's interpretation.
For investors who use subject-to in Tennessee, the practical playbook is consistent. Stay current on payments. Pay extra on principal when you can. Keep the insurance clean. Communicate with the seller every month for the first year. Have a replacement loan in your back pocket in case the lender calls the loan, and have a plan for what you would do if the seller declared bankruptcy or got divorced. The strategy works, and the cash flow can be excellent, but the structure is fragile and one missed payment unwinds every benefit you built. Most experienced subject-to investors carry six months of payments in reserve for every property. That reserve is what separates the operators from the ones who lose properties when something goes wrong.
For sellers being approached with a subject-to offer, the questions to ask are direct. Who pays the mortgage every month and how do I verify it. What happens to my credit if you miss a payment. How long until you can refinance into your own name. Will you carry insurance with my lender as loss payee. The answers to those four questions tell you whether you are working with an operator who knows the structure or someone who watched a YouTube video last week. The strategy works for both sides when both sides go in with eyes open. It collapses badly when either side is winging it, and the collapse always costs more than whatever the deal saved.
