Most people assume that getting a mortgage means going through a bank. Full stop. That assumption costs some buyers real opportunities, and I’ve watched it happen more times than I’d like to count.

Seller financing, sometimes called owner financing or a purchase money mortgage, is an arrangement where the person selling the house acts as the lender. Instead of you getting a loan from a bank and handing the proceeds to the seller, you make monthly payments directly to the seller over a set term, according to a promissory note you both sign. The seller holds a lien on the property until you’ve paid off the agreed balance. Simple in concept, complicated in execution.

I’ll be honest: when I was underwriting at a regional bank in the mid-2000s, I thought seller financing was mostly a tool for buyers who couldn’t qualify anywhere else. People in credit trouble, self-employed borrowers with messy tax returns, that kind of thing. What surprised me, after years of seeing how deals actually get made, is how often seller financing makes sense for buyers who could qualify conventionally but choose not to, because the deal structure works better for them. And sellers who have low or no mortgage balances can generate steady income from a note instead of parking cash in a money market account.

That said, this isn’t a magic workaround. There’s real risk on both sides, and most of the explainers out there skip right over the parts that can wreck you.

How the Mechanics Actually Work

The seller and buyer negotiate a sale price, a down payment, an interest rate, and a loan term. Those get written into a promissory note, which is the buyer’s legal promise to repay. Separately, a mortgage or deed of trust is recorded against the property, which gives the seller a security interest, meaning they can foreclose if you stop paying.

Loan terms vary widely. Some seller-financed deals run 30 years, just like a conventional mortgage. Most don’t. What you see far more often is a shorter amortization, say 20 or 25 years, with a balloon payment due at year 5 or 7. The buyer pays monthly as if the loan were fully amortizing, but at the end of the balloon period, the remaining balance comes due all at once. The assumption is that by then, the buyer will have improved their credit, grown their income, or built enough equity to refinance into a conventional loan.

That balloon structure is the single biggest risk for buyers. If you can’t refinance when the balloon comes due, and the seller won’t extend, you’re facing foreclosure. This isn’t theoretical. I’ve seen it happen.

There are also hybrid structures. Land contracts (also called contracts for deed) are common in the Midwest: the buyer takes possession but the seller retains legal title until the loan is paid in full. The risk there is asymmetric and severe for buyers. If you miss a payment, in many states the seller can cancel the contract and keep everything you’ve paid. No foreclosure proceeding required. Read that again.

The appeal is speed and flexibility. No appraisal required by an outside lender. No weeks of waiting for underwriting. No debt-to-income ratio being computed against Freddie Mac guidelines. The seller can decide to lend based on whatever criteria they choose, including your job stability, your story, your track record with the property if you’ve been renting it from them.

Interest rates on seller-financed deals are typically above conventional market rates. That’s the tradeoff for the flexibility. How much above? It depends entirely on negotiation, but don’t expect the seller to charge you below what they could earn in a reasonably safe investment. They’re taking on credit risk and holding an illiquid asset.

Down payments also tend to be higher than conventional minimums. A seller carrying a note usually wants 10 to 20 percent down, sometimes more, because their protection against default is that down payment equity. They’re not Fannie Mae. They don’t have mortgage insurance programs. The skin in the game is what keeps you paying.

One thing buyers miss entirely: you still need an attorney. Not a real estate agent, not just a title company. An actual real estate attorney who reviews the promissory note, the mortgage or deed of trust, the due-on-sale clause situation, and the exact terms of any balloon payment. The Consumer Financial Protection Bureau (CFPB) has published guidance on seller financing that’s worth reading before you sign anything, specifically around balloon loans and your right to receive a proper loan disclosure.

The Seller’s Side of This Equation

Sellers who consider owner financing are almost always in one specific situation: they own the property free and clear, or close to it. If there’s an existing mortgage on the home, a conventional due-on-sale clause means the bank can demand full repayment the moment title transfers. Selling via owner financing while a mortgage exists on the property is a serious legal risk that most sellers (and, frankly, some agents) don’t fully think through.

Why would a seller want to do this? A few reasons that are legitimate. First, an installment sale can spread capital gains tax liability across multiple years rather than triggering a large one-time tax event, which matters a lot to sellers with low basis in the property. They should run this by a CPA, not take my word for it. Second, the interest income can be attractive compared to CD rates. Third, seller financing can attract more buyers and potentially justify a higher sale price, since you’re offering something a conventional market doesn’t.

The risk to sellers is obvious: the buyer stops paying. Unlike a bank with a full servicing operation and legal team, an individual seller has to pursue foreclosure themselves. That takes time, money, and nerves. It’s also worth knowing that under the Dodd-Frank Act, sellers who offer financing on more than one property in a 12-month period are generally subject to mortgage origination regulations, including requirements around a buyer’s ability to repay. The Federal Housing Finance Agency (FHFA) doesn’t regulate seller financing directly, but the federal framework matters here, and ignoring it creates liability.

Negotiating a Deal That Doesn’t Blow Up Later

The term that tends to get glossed over is the interest rate adjustment provision. Some seller-financed notes have fixed rates for the full term. Others have adjustable provisions, where the rate can change after a certain period. Read the note language, not just the term sheet.

Title insurance is non-negotiable. Get it. The seller may push back, but you need an owner’s policy. A title search should happen before closing, full stop.

Loan servicing is another thing most people don’t think about until there’s a problem. Who tracks the payment history? Who issues year-end statements for your tax records? Who handles the payoff statement when you refinance? There are third-party loan servicing companies that handle this for a modest monthly fee (often $25 to $50). Using one protects both sides. It creates a paper trail that matters if there’s ever a dispute.

If any of this sounds complex, consider picking up a resource like The Complete Guide to Real Estate Finance for Investment Properties (Amazon, commission may apply), which covers the mechanics of non-conventional financing in more depth than most deal-specific guides.
