Creative finance exists because of a gap. With rates near 7%, a huge share of American homeowners are sitting on mortgages locked in at 3% or less — and a property carrying that debt is worth more with the loan attached than without it. Assuming a $250k balance at 3% instead of borrowing the same money at 7% saves roughly $560 a month in interest alone. That spread is not a gimmick; it is real, recurring money, and traditional financing has no way to capture it.
The other half of the gap is the seller with no urgency and a low basis: the landlord who paid $60k for a property now worth $200k, owns it free and clear, and faces a six-figure capital gain the moment a conventional sale closes. Cash offers do not solve that seller's problem — terms do. Sub-to, seller financing, and wraparounds are the tools that structure those deals. Here is how each one actually works, when it fits, and where the real risk sits.
subject-to: buying the house, leaving the loan
In a subject-to deal, you take title to the property while the seller's existing mortgage stays in place — you buy the house subject tothe existing financing. The deed transfers to you; the loan does not. You make the payments on the seller's mortgage, but the loan stays in the seller's name and on the seller's credit.
The entire economics of sub-to live in the rate spread. A $250k balance at 3% costs about $1,054/mo in principal and interest; the same balance at today's 7% costs about $1,663. That's roughly $600/mo of cash flow that exists purely because you kept the old debt alive — often the difference between a deal that carries itself and one that bleeds. You are not creating value with paint and granite; you are inheriting cheap money.
Now the part most gurus mumble through: the due-on-sale clause is real. Nearly every conventional mortgage gives the lender the right to call the full balance due when the property transfers. That right exists, it is enforceable, and no clever paperwork erases it. In practice, lenders rarely exercise it while payments arrive on time — a performing 3% loan is not a fire the servicer is eager to start — but "rarely" is not "never." If you do sub-to, you underwrite the call risk: reserves to cover a payoff or a fast refinance, a realistic exit (sale, refi, or wrap), and no deal where a called loan would sink you. Buy sub-to assuming the loan could be called, and structure so that surviving it is an inconvenience, not a bankruptcy.
seller financing: the seller becomes the bank
Seller financing is older and simpler: the seller carries the loan. Instead of a bank wiring funds at closing, the seller takes a promissory note and a mortgage (or deed of trust) from you, and you pay the seller monthly. It works best when the property is owned free and clear — no existing lender, no due-on-sale question, just two parties negotiating terms.
The negotiation has three levers: price, rate, and term. Here is the pattern that matters — sellers fixate on price, and investors should let them win it. A seller who gets his $200k number will often accept 4% interest and a 30-year amortization to get it, and that trade is heavily in your favor: paying $10k over market at 4% beats paying market price at 7% by a wide margin over any realistic hold. Concede the headline, take the terms.
Two structural basics. Amortization is the schedule the payment is calculated on — a 30-year amortization keeps the monthly payment low even if the loan doesn't run 30 years. Balloons are how sellers avoid waiting three decades for their money: the note amortizes over 30 years but the remaining balance comes due in full at year 5, 7, or 10. A balloon is a refinance deadline with a date on it, so model it like one — the property must support a conventional refi at realistic rates before the balloon hits, or you are negotiating an extension from a position of weakness.
wraparound mortgages: one payment wraps another
A wraparound (or "wrap") combines the two ideas: the seller has an existing mortgage, and instead of paying it off, they finance you with a new, larger note that wraps aroundthe old one. You pay the seller — say $1,800/mo on a wrap note — and the seller keeps paying their underlying $1,100/mo mortgage, pocketing the spread. Title transfers to you; the underlying loan stays in the seller's name. The risks stack accordingly: the underlying loan's due-on-sale clause still applies, and you carry a dependency the other structures don't have — if the seller pockets your payment and skips theirs, the underlying lender can foreclose on a property you own. Wraps demand third-party loan servicing and airtight documentation, and several states regulate them specifically. This is attorney territory, not handshake territory.
when each tool fits
Creative finance is not a personality; it is a toolbox, and each tool has a matching seller.
- Sub-tofits when there is low-rate existing debt and a motivated seller — pre-foreclosure, divorce, relocation, a landlord done with tenants. The seller needs debt relief more than cash, and the 3% loan is the asset you're really buying.
- Seller financingfits a free-and-clear property with a tax-motivated seller. An installment sale spreads the capital gain across the years payments are received instead of recognizing it all at once — for a long-hold landlord with a low basis, that deferral plus monthly interest income routinely beats a lump sum they'd owe taxes on and then struggle to reinvest at a decent yield. (The tax treatment varies by situation; the seller should confirm it with their CPA.)
- Wraps fit the narrow overlap: existing debt that's worth keeping and a seller who wants income rather than a payoff.
The common thread: high equity and long ownership. A seller who bought two years ago at 95% loan-to-value has nothing to be creative with. Screening for equity and hold time before you write the offer is most of the game.
the honest risk section
Creative finance has a guru problem, so let's be blunt about what can go wrong.
Due-on-sale. Covered above, repeated here because it is the risk: on any sub-to or wrap, the lender can call the underlying loan. Exit plan and reserves are not optional.
Servicing and escrow hygiene.Use a licensed third-party loan servicer on every seller-carried or wrapped note. The servicer collects payments, disburses to the underlying lender, tracks taxes and insurance escrows, and produces the paper trail. "I'll just Venmo the seller" is how these deals die in year three.
Insurance naming.The insurance policy has to reflect who actually owns and who holds a lien — get it wrong and a claim can be denied, or the policy change itself can flag the servicer. How to structure it depends on the deal; have your agent and attorney align it deliberately rather than leaving the seller's old policy in place and hoping.
Do it with an attorney. This is not a no-paperwork strategy — it is a more-paperwork strategy. Proper closing through a title company or attorney, recorded deed, written disclosures to the seller, a real note and mortgage. Several states specifically regulate these transactions (Texas is the best-known example), and the rules vary by state — use licensed professionals in the state where the property sits, every time. The cost of doing it right is a few thousand dollars; the cost of doing it wrong is the deal, and sometimes worse.
running the numbers
Creative structure does not exempt a deal from math. Whatever payment you end up with — assumed, seller-carried, or wrapped — the property's income still has to cover it with margin. Take the rent, subtract taxes, insurance, and realistic operating costs, and divide the remaining net income by the actual all-in payment; the DSCR calculator runs this in a minute, and on a wrap you run it against the wrap payment, not the underlying loan. If the ratio is under 1.2, the cheap debt is decorating a bad deal.
Model the full hold, not just month one: balloon dates, the refi rate you'd realistically face if a loan gets called, vacancy, and capex — the rental property analyzer handles the whole projection. And note that creative finance stacks with everything else: a sub-to acquisition can front-end a BRRRR cycle, with the low-rate debt carrying the property through rehab and seasoning. The tools compound — but only for deals that were sound before the structure got clever. Run the numbers first; get creative second.
