Seller Financing a House: How to Carry the Mortgage Yourself

What seller financing actually is

Seller financing a house means you, the owner, act as the lender instead of a bank. The buyer gives you a down payment and signs a promissory note promising to pay the rest over time, with interest. You keep a lien on the property, usually through a mortgage or a deed of trust, until the balance is paid in full. People also call this owner financing, a seller carryback, or holding the note.

This is not the same as renting or a lease option. In a true seller-financed sale, title transfers to the buyer at closing. They own the home, pay the property taxes and insurance, and can sell or refinance it, exactly as if they had a bank loan. You simply hold the debt. If they stop paying, you have the same remedy a bank has: you enforce your lien.

Owner financing is rare for a reason. Most buyers use a mortgage, and most sellers want their cash. The National Association of Realtors reports that buyers continue to finance their home purchases similar to years past, with 74 percent of home buyers financing the purchase, a share that decreases as the buyer's age increases. The homes that get owner-financed tend to be paid-off properties sold to buyers who cannot qualify for a conventional loan, or sales between people who already know and trust each other. If you are considering it for a relative, read our guide to selling a house to a family member first, because the tax rules stack together.

The two documents that make it work

A seller-financed deal runs on two legal instruments. Get them wrong and you can lose your security in the house.

The promissory note

The note is the buyer's written promise to pay. It spells out the loan amount, the interest rate, the payment schedule, the term, any balloon date, late fees, and what counts as default. This is the IOU. Without a clean, enforceable note, you are relying on a handshake.

The mortgage or deed of trust

The security instrument ties that promise to the house. It is what lets you take the property back if the buyer defaults. Whether you use a mortgage or a deed of trust depends on your state, and that choice drives how you foreclose later. If you want to understand how ownership documents differ, our explainer on the warranty deed versus quitclaim deed covers the basics of what actually transfers at closing.

The IRS recognizes these instruments directly. It notes that the buyer's obligation to make future payments to you can be in the form of a deed of trust, note, land contract, mortgage, or other evidence of the buyer's debt.

How a seller-financed deal is structured

Every carryback comes down to four numbers: the sale price, the down payment, the interest rate, and the term. A fifth, the balloon date, only appears in some deals and is heavily restricted for owner-occupant buyers.

Down payment

Because you are taking the buyer's default risk instead of a bank, sellers usually ask for more money down than a mortgage lender would. A larger down payment does two things: it gives the buyer real equity to lose if they walk, and it gives you a cash cushion. Down payments of 10 to 20 percent or more are common in owner-financed deals, though there is no legal minimum. The more the buyer puts down, the less likely they are to hand the keys back the first time money gets tight.

Interest rate

You set the rate, but you cannot set it at zero. The IRS requires a minimum. If the contract does not provide adequate stated interest, part of the stated principal may be recharacterized as unstated interest or original issue discount for tax purposes, and you must use the applicable federal rate to figure the amount. The applicable federal rates are published monthly. In a high-rate market, many sellers price their carryback a point or two above or below prevailing mortgage rates, depending on how badly the buyer needs the deal.

Term and balloon

You can amortize the loan over a long schedule, say 30 years, to keep the buyer's monthly payment affordable, then set a balloon payment that forces them to refinance or pay you off in five to ten years. That structure is popular with investors. But if your buyer will live in the home, the balloon is usually off the table under federal rules, which we cover next. A rent-to-own arrangement solves a different problem; see our breakdown of how rent-to-own homes really work if the buyer is not ready to own yet.

Not sure owner financing is your best move?

A top local agent can price your home, tell you whether a normal cash sale would clear faster, and structure a carryback only if it truly serves you.

Enter a sale price, down payment, interest rate, and amortization term to see the monthly payment the buyer would owe you and the total you would collect with interest. The last input compares that against selling for cash today and investing the proceeds at a market return. Change the numbers to see the tradeoff for your own deal.

Notice what the default numbers show: on a $400,000 house, holding the note nets a big pile of interest, but a lump-sum cash sale invested at a steady return can end up worth more in nominal dollars over 30 years. That is the honest tradeoff. Owner financing wins on income and tax deferral, not on raw total dollars, unless you cannot get a cash buyer at all.

The Dodd-Frank and CFPB rules you cannot skip

If your buyer will live in the home, federal consumer-protection law treats you a bit like a bank. The Dodd-Frank Act and the CFPB's Loan Originator Rule restrict seller financing of residential property secured by a mortgage, potentially treating the seller as a loan originator subject to ability-to-repay and licensing requirements, unless the seller qualifies for an exclusion.

Two exclusions matter for ordinary homeowners. There is a one-property exclusion, in which a natural person, estate, or trust provides seller financing for only one property, and a three-property exclusion for a seller financing entity that finances three or fewer properties. The single-property route is the one most individual sellers use.

Here is the catch that surprises people. Under the three-property exclusion, the loan must meet strict structural rules. The Dodd-Frank definition of mortgage originator exempts an individual, estate, or trust that provides mortgage financing for no more than three properties in any 12-month period only if the seller did not construct the home, the loan is fully amortizing with no balloon mortgage allowed, and the seller documents in good faith that the buyer has a reasonable ability to repay. The loan must also have a fixed rate, or be adjustable only after five or more years, subject to reasonable annual and lifetime caps.

Two more limits apply broadly. Builders are prohibited from using owner financing under these exemptions. And under either exception there can be no mandatory arbitration, and the parties cannot waive the Dodd-Frank requirements or restrictions.

How the installment sale tax break works

This is the reason many sellers carry a note. Instead of paying capital gains tax on your entire profit in the year you sell, you can spread the gain across the years you actually collect payments.

An installment sale, defined by Internal Revenue Code section 453 and IRS Publication 537, is a sale of property in which the seller receives at least one payment after the close of the tax year of the sale, which allows the seller to report and pay tax on the gain proportionally as payments are received rather than recognizing the entire gain in the year of sale. By default, this treatment is automatic. If a sale qualifies as an installment sale, the gain must be reported under the installment method unless you elect out, which means recognizing the entire gain in the year of sale.

Each payment you receive is split into three parts. In each year you receive a payment, you include in income both the interest part and the part that is your gain on the sale, and you do not include the part that is the return of your basis in the property. The gain slice is calculated with a gross profit percentage. Under the installment method, income is recognized over the years payments are received by multiplying the payments received during the year by the gross profit percentage, which is the gross profit on the sale divided by the total contract price.

The interest is taxed differently from the gain. You must report interest as ordinary income. So the monthly checks you collect are part tax-free return of your money, part capital gain, and part ordinary-income interest. An installment sale is reported on Form 6252, Installment Sale Income.

Where the break does not apply

The installment method has hard limits. Installment method rules do not apply to sales that result in a loss. And it does not erase depreciation recapture. You must report any portion of the gain from the sale of depreciable assets that is ordinary income under the depreciation recapture rules in the year of the sale. That matters if you rented the house out. Read the primary source, IRS Publication 537 on installment sales, and pair it with our guide on saving on real estate capital gains taxes before you commit.

How to vet a buyer's ability to pay

You are lending a person hundreds of thousands of dollars secured only by a house you would rather not get back. Vet them the way a lender would. Federal law effectively requires it for owner-occupant deals anyway, since you must document a reasonable, good-faith determination that the buyer can repay.

What happens if the buyer defaults

This is the part sellers underestimate. When the payments stop, you do not get an instant refund. You get a legal process, and which process depends on your state and your security instrument.

Foreclosure

If you hold a mortgage or deed of trust, you foreclose the same way a bank does. In states that allow non-judicial foreclosure through a deed of trust, the process can be relatively fast. In judicial-foreclosure states, you go to court, which can take many months and real legal fees. Either way, you may take the house back, but its condition after a distressed owner leaves is often worse than when you sold it.

Forfeiture under a land contract

Some sellers use a land contract, also called a contract for deed, where title stays with the seller until the buyer pays in full. In some states, that lets you use forfeiture, a faster remedy to cancel the contract and keep payments already made. But many states have curbed forfeiture and require a foreclosure-style process anyway, and the buyer may have accrued significant equity a court will not let you simply erase. This route is legally treacherous and varies enormously by state.

• The buyer stops paying property taxes or insurance. A tax lien can jump ahead of your mortgage. Require proof of payment every year and consider escrowing.
• A tiny down payment. If the buyer has almost nothing to lose, default is cheap for them and expensive for you.
• Balloon due date with no refinance plan. If the buyer cannot qualify for a bank loan now, betting they will in five years is a gamble you are financing.
• Deferred maintenance you cannot see. Once they own it, you cannot control upkeep. If you foreclose, you inherit whatever they let slide.

If a default does happen, understanding your options early saves money. Our guide on the alternatives to foreclosure is written for borrowers, but it shows you the moves a struggling buyer might make and how a workout can beat a court fight.

The honest case against seller financing

Here is the counterpoint the seminar gurus skip. Seller financing is a good fit for a narrow set of situations, and a bad idea for the rest.

If you owe money on the property, look at other paths first. Our guides on selling when you still owe on the mortgage and marketing an assumable mortgage often solve the same buyer-can't-qualify problem without turning you into a lender for the next 30 years.

Frequently asked questions

The bottom line

Seller financing is a legitimate tool, not a magic trick. It shines when you own a house outright, you have a specific buyer a bank turned down for a fixable reason, and you want interest income plus a spread-out tax bill. It fails when you still owe a mortgage, when you need your cash now, or when you are using it to prop up a price the market will not pay. The federal rules are real, the tax rules are specific, and the downside of a default lands entirely on you. Before you decide, get an honest read on whether a normal sale would work, and put a real estate attorney and tax pro on your team. If the math and the buyer both hold up, carrying the note can be a smart, deliberate choice. If they do not, it is an expensive way to learn what a bank already knew.
