What Is Seller Financing? 6 Rules That Protect Sellers

What is seller financing? It’s a home sale where you, the seller, act as the bank. Instead of bringing a mortgage lender to closing, the buyer signs a promissory note to you and pays you monthly, with interest, until the balance is paid off or refinanced. You keep a lien on the house until they do.

I’ve been analyzing seller-side deals for years, and “what is seller financing” lands in my inbox more than almost any other seller question, usually with a lot of excitement behind it and not much preparation. Done right, it can get you a higher price, a faster close, and years of interest income. Done casually, it can turn your biggest asset into a part-time job chasing payments. This guide covers the mechanics, the math, the federal rules almost nobody reads, and the six protections I’d insist on before carrying a note.

What Is Seller Financing, Exactly?

In a normal sale, the buyer’s bank wires the purchase money at closing and you walk away. In a seller-financed sale, there is no bank wire for the financed portion. The buyer gives you a down payment, signs a promissory note for the rest, and you record a mortgage or deed of trust against the property. The buyer goes on the deed and owns the home. You hold the debt, exactly the way a lender would.

You’ll hear it called owner financing, seller carryback, or “holding the note.” Same thing. There are messier cousins, too. A land contract (also called a contract for deed) keeps legal title in your name until the buyer finishes paying, and a wraparound mortgage layers the buyer’s payments over your existing loan. I’d steer clear of both in most cases. Contracts for deed have a long history of ending badly, and several states now regulate them hard. The clean structure, note plus recorded deed of trust, is the one title companies, servicers, and courts all understand.

The math on a $400,000 seller-financed sale

Numbers make this concrete. Say you’re selling at $400,000 and a buyer offers 15% down with you carrying the rest.

• Down payment to you at closing: $60,000
• Amount you finance: $340,000
• Terms: 7% interest, payments calculated on a 30-year schedule, balloon due in year five
• Monthly payment to you: $2,262
• Interest you collect in year one: about $23,691

At the five-year balloon, the buyer refinances or sells and pays you the remaining balance, about $320,047. Add it up and you’ve collected roughly $115,769 in interest over those five years on top of your full price. That’s the pull. A bank would have earned that money. Instead, you did.

The structure is negotiable end to end: rate, down payment, amortization period, balloon or no balloon. Which is exactly why the paperwork matters so much. Every term you forget to negotiate is a term that defaults against you. My walkthrough of the real estate purchase agreement clauses that protect sellers applies double here, because the purchase contract and the financing documents have to agree with each other.

Why Would a Seller Ever Agree to This?

Four reasons come up over and over in real deals.

A bigger buyer pool. When mortgage rates are high, plenty of solid buyers, self-employed people, recent retirees with assets but lumpy income, don’t fit the banks’ boxes. Offering terms puts your listing in front of them. Sellers offering financing can also hold firmer on price, because they’re providing something scarce.

Monthly income. For downsizers especially, trading a paid-off house for a note that pays $2,262 a month beats parking the proceeds in a savings account, if you can stomach the risk.

A tax lever. The IRS treats this as an installment sale: a sale where you receive at least one payment after the tax year of the sale. By default you report the gain as the payments come in, on Form 6252, instead of all at once, though you can elect out and report it all in year one. Interest you collect is ordinary income. And if the home was your primary residence, the home-sale exclusion I covered in my guide to capital gains tax on a home sale may shelter most or all of the gain anyway. Run it past a CPA before you sign anything.

Speed. No lender means no underwriting file, no appraisal contingency ordered by a bank, no loan-committee surprises the week of closing.

The honest counterweight: you are taking the risk the bank refused to take, usually with less cushion than a bank has. Price that risk. Don’t give bank-rate terms to a borrower no bank would touch.

The Federal Rules Most Sellers Have Never Heard Of

Here’s the part that surprises almost everyone I talk to. After Dodd-Frank, Regulation Z treats people who extend home financing to consumers as “loan originators,” a category with licensing and compliance duties you do not want. Ordinary sellers escape that only by fitting one of two exclusions spelled out in 12 CFR §1026.36, and the exclusions have teeth.

The one-property exclusion. A natural person, estate, or trust financing the sale of only one property in any 12-month period qualifies if the property secures the loan, you didn’t build the house as part of a construction business, the payment schedule never results in negative amortization, and the rate is fixed, or adjustable only after five or more years with reasonable caps. A balloon payment is allowed here, which is why the five-year balloon shows up in so many of these deals.

The three-property exclusion. Finance two or three properties in 12 months and the bar rises: the loan must be fully amortizing, no balloon at all, and you must determine in good faith that the buyer has a reasonable ability to repay.

Then your state adds its own layer. Texas, for one, regulates executory contracts like contracts for deed far more strictly than a standard note-and-deed-of-trust sale, one more reason I keep steering people to the clean structure. If you’re selling there, my team’s Texas flat fee MLS listing page covers the state-specific selling process. Wherever you are, a local real estate attorney should draft or at least review the note. This is not the document to pull off a template site.

Seller Financing vs. a Traditional Sale

	Seller financing	Traditional sale
Cash at closing	Down payment only	Full proceeds
Who carries lender risk	You	The buyer’s bank
Buyer pool	Wider, includes bank-rejected buyers	Mortgage-approved buyers only
Income after the sale	Monthly principal and interest	None
Sale price	Often a premium for the terms	Market price
If the buyer defaults	You foreclose, at your expense	Not your problem
Taxes on the gain	Spread over years (installment method)	Due for the year you sell

One row on that table outweighs the rest for me: if the buyer defaults, you foreclose. Not “keep the house and re-list it next weekend.” Foreclose, following your state’s process, on your own dime, possibly with the buyer still living there. Every protection in the next section exists because of that row.

6 Rules Before You Carry the Note

1. Get a real down payment. I want 10% at absolute minimum, and 15% or more before I’d feel comfortable. Skin in the game predicts payment behavior, and the cushion is what protects you if you ever have to take the house back in worse condition than you sold it.

2. Underwrite like a bank. Credit report, income documents, tax returns. If you’re using the three-property exclusion, a good-faith ability-to-repay determination is required anyway. Do it even when it isn’t. The buyers who balk at documentation are the buyers who become case studies.

3. Hire a loan servicer. A licensed servicing company collects payments, tracks the balance, sends the tax forms, and keeps an arms-length record for a few hundred dollars a year. When a friendly deal goes sideways, the servicer’s ledger is what stands up in court, not your spreadsheet.

4. Close like a normal sale. Title company or attorney, title insurance, recorded deed of trust, real settlement statements. Skipping the formal closing to save a few hundred dollars is how sellers discover, years later, that their lien was never recorded.

5. Escrow taxes and insurance. Require proof of homeowner’s insurance naming you as an interested party, and collect tax and insurance escrow with the monthly payment. An uninsured fire in a seller-financed house is a total loss with your name on it.

6. Check your own mortgage first. Most mortgages carry a due-on-sale clause letting the lender demand full payoff when the property transfers. Selling with financing while your own loan is outstanding can trigger it. And on family deals, charge at least the IRS minimum rate, the applicable federal rate published monthly, or the IRS can treat the missing interest as a gift. I dug into that trap in my piece on how to sell a house to a family member.

What Is Seller Financing? Common Questions

What is seller financing in simple terms?
Ask ten agents “what is seller financing” and you’ll hear the same core answer: the person selling the home also lends the buyer the money to buy it. The buyer makes a down payment, then pays the seller monthly with interest under a promissory note, while a recorded mortgage or deed of trust lets the seller foreclose if payments stop.

Who holds the title in a seller-financed sale?
In the standard structure, the buyer takes title at closing and the seller records a lien, the same arrangement a bank would have. If the seller keeps title until payoff, that’s a contract for deed, a structure several states restrict and one I’d generally avoid on both sides of the deal.

What happens if the buyer stops paying?
You foreclose under your state’s process, which takes months and costs real money even in fast states. This is why a serious down payment, a loan servicer keeping clean records, and escrowed taxes and insurance matter so much. They turn a default from a disaster into a bad quarter.

Can I offer seller financing if I still have a mortgage?
Usually you shouldn’t. Most mortgages have a due-on-sale clause, so transferring the home can let your lender call the whole loan due. Wraparound structures exist, but they layer your obligation under the buyer’s payments and need an attorney who does them regularly. Sellers who own the home free and clear are who this strategy is really built for.

How is seller financing taxed?
For the IRS, the answer to “what is seller financing” is simple: an installment sale. By default you report the gain as payments arrive, using Form 6252, rather than all in the year of sale. Interest you receive is taxed as ordinary income. If the home was your primary residence, the capital gains exclusion may wipe out most of the gain entirely.

The Bottom Line

So, what is seller financing? It’s you keeping the profit a bank would have made, in exchange for taking the risk a bank would have taken. For a free-and-clear seller who wants income, a wider buyer pool, and a tax bill spread over years, it’s a genuinely strong play. For a seller who needs every dollar at closing, it’s the wrong tool, no matter how tempting the interest math looks.

Either way, terms only help if buyers actually see them. A seller-financed listing sitting on a yard sign reaches the neighborhood; the same listing on the MLS reaches every agent and every portal in your market. That’s the whole point of our for sale by owner program: $95, on the MLS, “seller financing available” right in the listing remarks, and you keep the commission you didn’t pay. Carry the note if the numbers work. Just make sure the whole market gets the chance to bid first.
