To write an owner finance contract, you assemble three matched documents — a purchase agreement, a promissory note, and a security instrument (mortgage or deed of trust) — that together sell the property, create the debt, and give the seller a lien to enforce it. Before you draft, you have to pick a legal structure, confirm you qualify for a Dodd-Frank exemption, set an interest rate that clears the IRS floor without breaching your state’s usury cap, and handle required disclosures. After you draft, you notarize and record. Skip any of those and you can end up with an unenforceable agreement, a surprise tax bill, or a lender calling your existing mortgage due.
Decide on a Structure Before You Draft
The structure controls when the buyer receives title and which documents you’ll prepare.
In a deed transfer with a mortgage or deed of trust, the seller conveys the deed to the buyer at closing, and the buyer signs a promissory note plus a security instrument giving the seller a lien. The buyer holds legal title from day one; the seller’s recorded lien allows foreclosure on default. This is the more common structure today because the buyer has clear title to insure and refinance against while the seller’s lien is protected.
In a contract for deed (land contract), the seller keeps legal title until the buyer finishes paying. The buyer gets possession and equitable interest but no deed until final payment. On default, the seller may reclaim the property through forfeiture, though many states have added protections that make the process nearly as involved as foreclosure.
The rest of this guide assumes the deed-transfer structure, but most contract elements apply to land contracts as well.
Confirm You Qualify Under Federal Lending Rules
Many sellers assume federal lending regulations don’t reach them because they aren’t a bank. That’s wrong. Under the Truth in Lending Act’s Regulation Z, anyone who arranges a residential mortgage loan is a loan originator and generally needs a license. Seller financers can avoid that classification only through one of two narrow exemptions.
The One-Property Exemption
Available to a natural person, estate, or trust that finances the sale of only one property in any 12-month period. You must own the property and cannot have been the contractor who built the residence. The loan cannot cause negative amortization, and any adjustable rate must be fixed for at least five years with reasonable lifetime caps tied to a widely available index. Under this exemption you are not required to formally evaluate the buyer’s ability to repay.1eCFR. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
The Three-Property Exemption
Available to individuals, estates, trusts, and entities like LLCs that finance three or fewer properties in any 12-month period. The same ownership and non-contractor requirements apply, but the loan terms are stricter. The financing must be fully amortizing, and balloon payments are flatly prohibited. You must also determine in good faith that the buyer has a reasonable ability to repay. The regulation doesn’t prescribe a method, but keeping records of the buyer’s income, debts, and credit history is the practical way to demonstrate good faith later.1eCFR. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
If you finance more than three properties in a year, or if you built the home you’re selling, neither exemption applies and you’ll need a mortgage loan originator license.
Balloon Payments
Under the three-property exemption, balloons are prohibited outright. Under the one-property exemption, the rule prohibits only negative amortization, so balloon structures are permitted. Even then, the conservative practice is a five-year minimum term before any balloon comes due. Balloons that mature in two or three years invite litigation and may not survive challenge in every jurisdiction.
Handle the Due-on-Sale Clause if You Still Have a Mortgage
If you still owe money on the property, address this before you draft anything. Nearly every conventional mortgage contains a due-on-sale clause allowing the lender to demand immediate repayment of the full balance if the property is sold or transferred without written consent, and federal law explicitly authorizes lenders to enforce those clauses.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions
Transferring the deed to an owner-financed buyer can trigger the clause. If you can’t pay off the balance, the lender can begin foreclosure, which puts the buyer in an equally bad position. The statute lists exceptions — transfers to a spouse, transfers resulting from a borrower’s death, transfers into a living trust where the borrower remains a beneficiary, and a few others — but a standard sale to an unrelated buyer using owner financing is not among them.2Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions
Talk to a real estate attorney before offering owner financing on a property with an existing loan. Some sellers work around it with a contract for deed (since legal title doesn’t transfer), a land trust, or by seeking the lender’s consent. Each option has trade-offs. Proceeding blind is the option that reliably causes problems.
Prepare Before You Start Drafting
Order a Title Search
Engage a title company to run a thorough title search before drafting. It confirms the seller owns the property free and clear or identifies liens that must be addressed. The legal description from the existing deed — the metes-and-bounds or lot-and-block description, not the street address — is what goes into your contract documents. Review any existing survey for boundary issues or easements.
Set Insurance Requirements
The contract should require the buyer to maintain hazard insurance for the full loan term, with the seller named on the policy. How the seller is named matters. A standard “loss payee” listing offers limited protection: the seller may not be notified of cancellation, and the seller’s right to proceeds can be voided by the buyer’s actions. Being named as “mortgagee” or “lender’s loss payee” is significantly better. Those endorsements guarantee the seller receives proceeds even if the buyer invalidates the policy and require the insurer to give 30 days’ notice before cancellation.
Provide Required Disclosures
Federal law requires sellers of homes built before 1978 to disclose known lead-based paint hazards before the purchase contract is signed. The seller must provide an EPA-approved lead hazard information pamphlet, share any available records or reports, and include a lead warning statement in the contract.3eCFR. 24 CFR 35.88 – Disclosure Requirements for Sellers and Lessors The buyer must also get a 10-day opportunity to conduct a lead inspection before becoming obligated under the contract, unless the buyer waives that period in writing.4U.S. Environmental Protection Agency. Lead-Based Paint Disclosure Rule (Section 1018 of Title X) Most states add their own property condition disclosure requirements that apply regardless of financing method.
Hire an Attorney
This is not a form-filling exercise. A real estate attorney should draft or review the documents before either party signs. The attorney confirms the contract complies with state requirements, that the promissory note and security instrument are enforceable, and that the Dodd-Frank exemption conditions are actually met. Foreclosure procedures, recording requirements, usury limits, and redemption periods vary widely by state, and a contract that works in one state may be inadequate in another. Attorney fees now are a fraction of what litigating an unenforceable contract costs later.
Set the Interest Rate Within the Legal Range
The rate isn’t purely negotiable. The IRS sets a floor; your state sets a ceiling.
If the stated interest rate falls below the Applicable Federal Rate, the IRS treats the difference as “imputed interest” and the seller owes tax on interest income never actually received.5Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The IRS publishes AFRs monthly for short-term loans (three years or less), mid-term loans (three to nine years), and long-term loans (over nine years). As of April 2026, the long-term AFR — the rate most relevant to owner-financed real estate — is 4.62% for annual compounding.6Internal Revenue Service. Applicable Federal Rates These change monthly, so check the current rate at closing.
Every state caps the maximum interest rate a private lender can charge, though the limits vary. Exceeding the cap can void the interest obligation entirely or expose the seller to penalties. Check your state’s usury statute before finalizing.
Draft the Three Core Documents
An owner finance transaction runs on three documents that must align perfectly on every financial term. Draft the promissory note and security instrument side by side, not sequentially. A discrepancy between them gives a defaulting buyer an argument to delay or block foreclosure.
The Purchase Agreement
The master document. It identifies the buyer and seller by full legal name and address, includes the complete legal description of the property pulled from the existing deed, and states the purchase price and down payment. It assigns responsibility for property taxes, homeowner’s insurance, and maintenance. Closing costs and prorated expenses like taxes and utilities go here so neither party is surprised at closing.
The Promissory Note
The buyer’s written, signed promise to repay. A standalone document specifying principal balance, interest rate, payment amount, payment schedule, and maturity date.7Legal Information Institute. Promissory Note It should also address late payment penalties, prepayment terms, and what happens on a missed payment. The note is what creates the debt obligation. Without it, the seller has no enforceable claim for repayment separate from the property itself.
The Security Instrument
Either a mortgage or a deed of trust, depending on your state. When the buyer signs it, they give the seller a lien allowing foreclosure on default.8Consumer Financial Protection Bureau. Deed of Trust / Mortgage Explainer Two provisions matter most:
- An acceleration clause, which lets the seller demand the full remaining balance immediately on default rather than waiting for each missed payment.
- A power of sale, in deed-of-trust states, which allows a trustee to sell the property without going through court, making foreclosure faster and less expensive for the seller.
Define exactly what counts as default: not just missed payments, but failure to maintain insurance, failure to pay property taxes, or unauthorized transfer of the property.
Write in Language That Won’t Be Argued About
Use plain, specific language. Every ambiguous sentence is a future argument. “Buyer shall pay seller $1,850.00 on the first day of each calendar month” is enforceable. “Buyer shall make regular monthly payments” invites dispute over what “regular” means and when exactly payment is due. State every term as a concrete obligation with a date, a dollar amount, or a measurable standard.
Address these scenarios that templates routinely miss:
- Property tax escrow. Will the seller collect monthly escrow for taxes and insurance, or is the buyer responsible for paying them directly? Without escrow, if the buyer stops paying taxes the seller’s lien can be wiped out by a tax sale.
- Insurance lapse. The contract should give the seller the right to force-place insurance and add the cost to the loan balance if the buyer’s policy lapses.
- Transfer restrictions. Can the buyer sell or transfer the property before paying off the note? Most seller-financed contracts include their own due-on-sale clause requiring full payoff on transfer.
- Prepayment. Can the buyer pay off early without penalty? If there is a penalty, when does it expire?
Templates from legal document services can give you a starting point, but they cannot substitute for an attorney who knows your state’s recording requirements, foreclosure procedures, and consumer protection rules. Customize aggressively.
Write the Default Terms So You Can Actually Enforce Them
Default provisions are only useful if they’re specific enough to enforce. Define default clearly: a payment more than a set number of days late, failure to maintain insurance, failure to pay property taxes, unauthorized transfer of the property, or any other breach of contract terms. Then spell out the seller’s remedies.
In a deed-transfer structure the primary remedy is foreclosure, either judicial (through the courts) or non-judicial (through a trustee sale), depending on the state and the type of security instrument. Non-judicial foreclosure through a deed of trust is faster, but still requires multiple notices and waiting periods. Judicial foreclosure takes longer and may give the buyer a redemption period of several months to reclaim the property after sale.
Require the seller to provide written notice of default and give the buyer a reasonable cure period, typically 30 days, before accelerating the loan or beginning foreclosure. Most states require this notice regardless of what the contract says, so building it in avoids procedural challenges later. Pair it with the acceleration clause in the promissory note so the seller can demand the full remaining balance on default rather than suing for each missed payment individually.
Sign, Notarize, and Record
All parties sign the purchase agreement, promissory note, and security instrument. The security instrument must be notarized to be recordable. Notarization verifies the signers’ identities and confirms they’re signing voluntarily. Some states also require witnesses for certain real estate documents; your attorney or title company will know local requirements.
Record the security instrument with the county recorder’s office. This is not optional for the seller. Recording creates a public record of the lien and establishes the seller’s priority against later claims on the property. If the seller doesn’t record and the buyer takes out a second loan or has a judgment filed against them, the seller’s lien could end up behind those later claims or be unenforceable altogether. Recording fees generally run between $10 and $100.
Both parties should retain original copies of all signed and notarized documents. The buyer should receive copies of the promissory note, the security instrument, and any disclosure forms. The seller should keep the original promissory note in a secure location. It’s the physical evidence of the debt.
Plan for the Tax Reporting the Contract Creates
Seller financing creates an installment sale for federal tax purposes. Rather than reporting the full gain in the year of sale, the seller reports a proportional share of gain with each payment. The IRS defines an installment sale as any property disposition where at least one payment is received after the close of the tax year in which the sale occurs.9Office of the Law Revision Counsel. 26 USC 453 – Installment Method
Each payment contains three components: return of basis (not taxed), capital gain (taxed at capital gains rates), and interest income (taxed as ordinary income). The ratio of gain to total contract price stays constant across the loan. The seller reports annually on IRS Form 6252.10Internal Revenue Service. About Form 6252, Installment Sale Income
Sellers who receive $600 or more in mortgage interest during the year must furnish the buyer with a Form 1098 (Mortgage Interest Statement) and file a copy with the IRS. It’s the same form banks use. The IRS considers any obligation secured by real property to be a mortgage for reporting purposes, regardless of who holds the note.11Internal Revenue Service. Instructions for Form 1098 The buyer, in turn, may be able to deduct the interest as mortgage interest.
Because the administrative work is real — payment allocation between principal and interest, escrow disbursements, delinquency notices, year-end 1098s — many sellers hire a third-party loan servicer. Typical fees run $20 to $50 per month depending on loan complexity, and the servicer’s independent records also protect both parties in a dispute over whether payments were made or how they were applied.
