Subject-To (Sub2)

Subject-to (often written sub2 or subject-to existing financing) is a creative-financing technique in which a buyer takes ownership of a property while the seller's existing mortgage stays in place — in the seller's name. The buyer takes title 'subject to' that loan and typically makes the payments, but the mortgage is not formally assumed or paid off; it simply remains as-is.

Note: 'subject-to' here means subject to existing financing. The same words also describe a subject-to appraisal (valuing a property as if a rehab were complete) — a different concept entirely.

How a subject-to deal works

1. A seller has a mortgage (often at a low locked-in rate) and wants out — facing distress, relocation, or simply unable to sell conventionally.
2. The buyer acquires the property and takes title, leaving the existing loan in place.
3. The buyer makes the monthly payments on the seller's loan going forward.
4. The buyer may pay the seller little or nothing for their equity, or a negotiated amount.

The buyer effectively controls the property and benefits from the existing financing without qualifying for a new loan.

Why investors use subject-to

• Acquire the seller's low rate. In a higher-rate environment, taking over a 3–4% mortgage subject-to can produce far better cash flow than a new DSCR loan at current rates. This is the biggest driver of sub2's popularity.
• No new qualifying. The buyer doesn't apply for financing — useful for investors who are maxed out or can't easily qualify.
• Little money down. Subject-to deals often require minimal cash, especially when the seller has little equity.
• Speed and flexibility. No loan origination means a faster, simpler close.

The big risk: the due-on-sale clause

Nearly every mortgage contains a due-on-sale clause giving the lender the right to call the loan due in full if the property is transferred without paying it off. A subject-to transfer can trigger this clause. In practice lenders often don't call loans that are being paid on time, but the risk is real — if the lender accelerates, the buyer must refinance or pay off the loan quickly or face foreclosure. This is the central danger of sub2 and must be understood and planned for.

Other risks and considerations

• Seller's credit and liability. The loan stays in the seller's name — late payments hurt their credit, and they remain legally liable. Trust and clear documentation are essential.
• Insurance and escrow must be handled correctly so the existing lender isn't tipped off improperly and coverage stays valid.
• Documentation. Sub2 deals need careful paperwork (often with attorney involvement) — disclosures, authorization to manage the loan, and a plan for the due-on-sale risk.
• Exit. Many investors plan to refinance out of the subject-to loan within a few years, or hold and eventually sell.

Practical takeaway

Subject-to can be a powerful way to acquire property with attractive existing financing and little cash — but it carries genuine legal and due-on-sale risk that casual investors underestimate. Use experienced counsel, document everything, treat the seller's credit and liability with care, and have a refinance or payoff plan for the due-on-sale exposure. It's a legitimate strategy in the right hands, not a no-risk shortcut. This is general information, not legal advice.
