How to Owner Finance a House: Dodd-Frank, Taxes, and Default

To owner finance a house, you step into the bank’s role: you sell the property, extend credit to the buyer for the balance after any down payment, and hold a lien until the loan is paid off. Doing it correctly means clearing any existing mortgage on the property, fitting inside one of two federal exemptions for seller financing, vetting the buyer, drafting a promissory note and a security instrument that actually hold up, recording the security instrument with the county, and reporting the sale as an installment sale on your taxes every year until it’s paid.

Clear the Existing Mortgage First

If you still owe a bank on the property, deal with that before anything else. Federal law explicitly authorizes lenders to include a due-on-sale clause, which lets the bank demand full repayment of the remaining balance the moment the property is sold or transferred without the lender’s written consent.¹ If you can’t pay that balance, the bank can foreclose on a property your buyer thought they were purchasing.

The safest arrangement is owning the property free and clear before you offer to carry a note. Sellers with significant equity can sometimes pay off the remaining balance from the buyer’s down payment, but that requires careful coordination at closing. The statutory exceptions to the due-on-sale rule cover transfers to a spouse or child, transfers into a living trust where the borrower stays a beneficiary, and transfers by divorce or death; none of them cover a standard sale to an unrelated buyer.¹ Assume the clause applies to your deal.

Confirm You Qualify Under Dodd-Frank

Most sellers assume that because they’re not a bank, federal lending rules don’t touch them. That’s wrong. The Dodd-Frank Act and Regulation Z impose loan originator requirements on anyone who offers residential mortgage financing, and a seller outside the two available exemptions could face enforcement from the Consumer Financial Protection Bureau.

The One-Property Exemption

An individual, estate, or trust that finances only one property sale in any 12-month period qualifies for the narrower exemption, provided the seller owned the property, didn’t build the home as a contractor, and structures the loan so it doesn’t produce negative amortization.² The rate must be fixed, or if adjustable, can’t reset for at least five years and must be tied to a widely available index with reasonable annual and lifetime caps. Balloon payments are allowed under this exemption, which is why most single-sale owner-financed deals include one.

The Three-Property Exemption

Finance up to three property sales in a 12-month period and stricter rules apply. The loan must be fully amortizing, so no balloon. You also have to make a good-faith determination that the buyer can reasonably afford to repay.² Interest rate rules are the same: fixed, or adjustable only after five or more years with reasonable caps. This exemption is available to any “person,” including LLCs, unlike the one-property exemption, which is limited to natural persons, estates, and trusts.

Finance more than three properties in a year, or sell a home you built, and neither exemption applies. Proceeding legally in that situation requires a mortgage loan originator license under the SAFE Act.³

Check Your State’s Usury Cap

Every state caps the interest rate a private lender can charge, and some states set a different ceiling for seller-financed real estate than for other private loans. Charging above the cap can void the interest obligation entirely or trigger penalties such as forfeiture of all interest collected. Before you set a rate, confirm the ceiling in the state where the property is located. A real estate attorney familiar with local lending rules is the most reliable source.

Vet the Buyer

A bank spends weeks underwriting a borrower. You don’t need that infrastructure, but skipping vetting is how sellers end up chasing payments six months in. Under the three-property exemption, a good-faith ability-to-repay determination is legally required.² Under the one-property exemption it isn’t required, but it’s still common sense.

Pull a credit report to see how the buyer has handled past obligations and whether any judgments or liens are outstanding. Ask for at least two years of tax returns or W-2s to verify steady income. Run those numbers through a basic debt-to-income calculation to get a rough picture of whether the buyer can carry the monthly payment alongside their existing obligations. You aren’t aiming for bank-level precision. You’re trying to avoid a default that forces you into a foreclosure you didn’t want.

Set the Loan Terms

Owner-financed loans are more negotiable than institutional mortgages, but the Dodd-Frank exemptions constrain some of that flexibility. The terms you’ll need to decide:

Down payment. No federal minimum applies. A larger down payment reduces your risk and gives the buyer equity from day one. Ten to twenty percent is common.
Interest rate. Fixed, or adjustable only after five or more years with reasonable caps, to fit either exemption. It also has to stay below the state usury ceiling.
Loan term and amortization. Under the one-property exemption, a five-to-ten-year term with a balloon is standard, with monthly payments calculated on a 30-year amortization and the remaining balance due at the end. Under the three-property exemption, the loan has to be fully amortizing with no balloon.
Prepayment. Federal law prohibits prepayment penalties on residential loans that don’t qualify as “qualified mortgages,” and even on qualified mortgages, penalties are capped at 3% in the first year, 2% in the second, 1% in the third, and zero after that. Most owner-financed deals skip prepayment penalties entirely; sellers generally want to be paid off sooner, not later.⁴

A word on the balloon. The assumption behind a balloon is that the buyer will refinance into a conventional mortgage before the date arrives, and that assumption doesn’t always hold. If property values drop or the buyer’s credit hasn’t improved enough to qualify, refinancing may not be possible.⁵ The buyer defaults on the lump sum, you take the property back through foreclosure, and the property may have depreciated or been poorly maintained in the meantime. Price the balloon risk into your down payment and rate.

Draft the Promissory Note and Security Instrument

Two documents do the heavy lifting. The promissory note is the buyer’s written promise to repay the loan, spelling out the principal amount, interest rate, payment schedule, and any balloon date. The security instrument, called a mortgage in some states and a deed of trust in others, gives you a lien on the property. If the buyer stops paying, the lien is what lets you foreclose.

Both documents should include clear default and late-fee provisions. Define exactly what counts as a default: missed payments, failure to maintain homeowner’s insurance, failure to pay property taxes. Late fees in residential financing are commonly set as a percentage of the overdue payment, often around 4% to 5%. Spell out the grace period before a late fee kicks in and your right to accelerate the full loan balance if a default isn’t cured within a specified timeframe. Without an acceleration clause, you can only pursue the missed payments, not the full loan amount, which dramatically weakens your position.

Templates are available through title companies and legal document services, but having a real estate attorney review the documents before signing is worth the cost. An error in the legal description, a missing acceleration clause, or a rate that violates usury law can make the entire arrangement unenforceable. Attorney review of closing documents typically runs from a few hundred to a couple thousand dollars depending on complexity.

Sign, Notarize, and Record

Both parties sign the promissory note and security instrument in front of a notary, who verifies identities and witnesses the execution. The notarized security instrument then gets recorded at the county recorder’s or register of deeds office. Recording creates a public record of your lien, which protects your interest against later buyers or creditors who might otherwise treat the property as unencumbered. Many counties now accept electronic submissions alongside in-person filings.

Recording fees vary by jurisdiction. Some counties charge a flat fee per document, others charge by the page, and a few add surcharges for housing programs or fraud prevention funds. Budget for these at closing. Beyond recording, consider title insurance. An owner’s policy protects the buyer against hidden liens, ownership disputes, and errors in the public record; a lender’s policy protects your security interest. Neither is technically required, but going without either is a gamble that gets expensive if a title defect surfaces later.

Some states and localities also impose transfer taxes, typically ranging from a fraction of a percent to a few percent of the sale price, though more than a dozen states charge nothing at all. Check with the county recorder’s office or a local title company for the exact figure.

Handle Taxes Each Year

Owner financing creates tax obligations that catch many sellers off guard. The IRS treats the sale as an installment sale, which means you report a portion of the capital gain each year as payments come in rather than all at once in the year of the sale.⁶

Installment Sale Income

Each payment has three components: a return of your basis in the property (not taxable), your gain on the sale (taxable as capital gain), and interest income (taxable as ordinary income). The taxable gain portion is determined by a gross profit percentage. Divide the total gain by the contract price, and that percentage applies to the principal portion of every payment you receive.⁷ Report installment sale income on Form 6252 every year you receive payments, and expect to attach Schedule D and possibly Form 4797.⁶

Interest Income and Form 1098

The interest you collect each year is ordinary income, reported on Schedule B of Form 1040.⁸ A common misconception is that every seller carrying a note must file Form 1098 to report the interest the buyer paid. Form 1098 is only required if you receive the interest in the course of a trade or business and the amount exceeds $600 per year. A homeowner selling a single former personal residence and carrying back a mortgage is specifically exempt from the Form 1098 requirement.⁹ Investors who regularly finance property sales will likely meet the trade-or-business threshold and need to file.

Exchanging TINs With the Buyer

Your buyer can deduct the mortgage interest they pay you, but the paperwork is slightly different from a bank mortgage. The buyer reports the interest on Schedule A, line 8b, and must include your name, address, and taxpayer identification number. You’re required to provide your TIN, and the buyer is required to provide theirs. A failure on either side can trigger a $50 penalty per failure.¹⁰

If the Buyer Defaults

The default provisions in the promissory note aren’t boilerplate. They’re your roadmap if payments stop. The two basic options are foreclosing to take the property back or suing the buyer for the money owed. Which path is available, and how long it takes, depends on whether the state uses mortgages or deeds of trust and whether it requires judicial foreclosure.

In states that use deeds of trust, a non-judicial foreclosure is often possible and typically moves faster because it doesn’t require a court proceeding. In states that require judicial foreclosure, you file a lawsuit and wait for the court to authorize a sale. Either way, the process takes months and costs money in legal fees, which is why upfront vetting and a meaningful down payment matter. The down payment gives the buyer a financial stake that discourages walking away, and the vetting reduces the odds of default in the first place.

Reporting Payments to Credit Bureaus

One thing worth telling your buyer up front: payments on an owner-financed mortgage don’t automatically show up on credit reports. Banks and large mortgage servicers report to the major bureaus as a matter of course, but individual sellers have no obligation to do so and rarely set up reporting on their own. A buyer who makes five years of on-time payments may have nothing to show for it when they apply to refinance into a conventional loan, which is a problem for both sides of a balloon deal. Third-party loan servicing companies can handle payment collection and credit bureau reporting for a monthly fee. The buyer builds a documented payment history, and you get professional tracking of payments and any escrow accounts.
