What is Subject-To Financing?
Subject-to (also written as "sub-to" or "subject to existing financing") is a creative acquisition strategy where a buyer takes ownership of a property while the seller's existing mortgage stays in place. The buyer takes title to the property via deed and makes the mortgage payments, but the loan remains in the seller's name. The property transfers "subject to" the existing financing.
Subject-to deals are used when conventional purchases don't work -- most commonly when the seller has little or no equity, making a traditional wholesale transaction impossible. If the seller owes $180,000 on a property worth $190,000, there's no room for a below-market purchase and a wholesale fee. But a subject-to acquisition lets the buyer take over the payments, potentially at a favorable interest rate, and either rent the property for cash flow or hold it until enough equity builds to sell profitably.
How subject-to works
- Agreement: Buyer and seller agree on terms. The buyer gets the deed; the seller transfers ownership. The existing mortgage stays in the seller's name.
- Title transfer: The seller signs a warranty deed or quitclaim deed transferring ownership to the buyer. This is recorded at the county.
- Payment arrangement: The buyer begins making the mortgage payments directly to the lender, or the payments are handled through a servicing company.
- Insurance update: The buyer obtains a new insurance policy naming themselves as the insured and the lender as an additional interest.
When subject-to makes sense
- Low/no equity sellers: The seller can't sell conventionally because closing costs would exceed their equity. Subject-to lets them walk away from the mortgage payments without a short sale or foreclosure.
- Favorable existing rate: If the seller has a 3% mortgage from 2021 and current rates are 7%, taking over that loan is significantly cheaper than getting new financing.
- Pre-foreclosure saves: The seller avoids foreclosure and the credit damage. The buyer gets a property with minimal cash out of pocket.
- Rental strategy: The below-market interest rate creates stronger cash flow than a new loan would allow.
The due-on-sale risk
The biggest risk in subject-to transactions is the due-on-sale clause. Almost every mortgage includes this clause, which gives the lender the right to call the loan due (demand full repayment) if the property is transferred. In practice, lenders rarely exercise this right as long as payments are being made on time -- they'd rather collect interest than foreclose on a performing loan. However, the risk is real and should be understood by both parties.
Mitigation strategies include using a land trust to hold title (may avoid triggering automated due-on-sale detection), keeping payments current (the primary factor -- lenders monitor payments, not ownership changes), and having a refinance exit plan (ability to pay off the loan if called).
Subject-to vs seller financing
Subject-to and seller financing are both creative financing strategies, but they work differently. In subject-to, an existing bank loan stays in place. In seller financing, the seller IS the lender -- they hold a promissory note and the buyer makes payments directly to them. Seller financing requires the seller to own the property free and clear (or have enough equity to pay off their mortgage at closing).
Subject-to and wholesaling
Most traditional wholesalers don't deal with subject-to transactions because they require more complex structuring and the assignment model doesn't apply the same way. However, some wholesalers specialize in creative finance deals and can assign or JV on subject-to opportunities. Understanding subject-to expands the types of deals you can pursue, especially in markets where equity is thin and traditional wholesale spreads are hard to find.
