To fill out an owner financing contract, you match the right template to the instrument you’ve chosen (promissory note with mortgage or deed of trust, or a land contract), enter the parties and legal property description exactly as they appear on official records, set financial terms that comply with the IRS applicable federal rate and your state’s usury cap, add the clauses that govern default and day-to-day obligations, and then sign before a notary so the document can be recorded. The details below walk through each of those steps in the order you’ll actually do them.
Pick the Instrument Before You Pick the Template
Templates are not interchangeable. A promissory note paired with a mortgage or deed of trust transfers the deed to the buyer at closing and gives the seller a recorded lien; if the buyer defaults, the seller forecloses. A land contract (also called a contract for deed) keeps legal title with the seller until the buyer pays in full, and the buyer holds equitable title in the meantime.
Which structure is standard in your state varies, and a local real estate attorney will usually have a preferred form. Confirm the template you download matches the instrument you’ve chosen before you fill in a single field.
Gather This Information First
Missing any of the following will either stall drafting or produce a contract the county won’t record.
- Full legal names and addresses of both parties. Match the names to government-issued identification exactly. For a trust or LLC, use the full registered name.
- Legal property description. Copy it verbatim from the current deed: lot and subdivision, or metes-and-bounds measurements. A street address alone is not enough to make a real estate contract enforceable.1Cornell Law Institute. Deed
- Title search results. A professional search runs roughly $50 to $400 and surfaces existing liens, easements, and boundary problems. Any issues need to be cleared or disclosed before closing.
- Title insurance. An owner’s policy protects the buyer against undiscovered defects. The seller-lender should also consider a lender’s policy, which covers the loan balance.
- Purchase price and down payment. Down payments in owner-financed deals commonly land between 10% and 20%, but the parties can set any amount.
Use a template built for your state. Real estate contract requirements differ by jurisdiction, and templates from state real estate commissions or attorney-reviewed platforms will pre-format fields for the disclosures your state expects.
Setting the Financial Terms
The financial section is where the contract does most of its work. Every figure here determines the true cost of the loan and whether the terms comply with federal rules.
Interest Rate
State the interest rate clearly. The IRS sets a floor: if you charge less than the applicable federal rate (AFR), the IRS will treat the shortfall as imputed interest and tax the seller on income they never received.2Internal Revenue Service. Publication 537 (2025), Installment Sales The AFR is published monthly. For April 2026, the long-term AFR (for loans over nine years) is 4.62% compounded annually.3Internal Revenue Service. Rev. Rul. 2026-7 Check the current month’s rate before you finalize.
State usury laws cap the maximum rate a private lender can charge, and the caps vary widely. Going over the cap can void the interest obligation entirely and expose the seller to penalties. Look up your state’s limit before writing a number in.
Amortization and Balloon Payments
The amortization schedule decides how each payment splits between principal and interest and how long the buyer has to pay off the loan. A fully amortizing 15- or 30-year schedule brings the balance to zero on its own.
Many owner-financed deals use a balloon structure instead: payments are calculated on a 30-year schedule, but the entire remaining balance comes due after a shorter period, commonly five to ten years, with the buyer expected to refinance before that date.4Consumer Financial Protection Bureau. What Is a Balloon Payment? When Is One Allowed? Whether you’re allowed to include a balloon depends on how many properties the seller has financed in the last year, which is covered further down.
Spell out the payment frequency, the exact due date each period, and how payments must be delivered. Including ACH or electronic transfer details up front cuts down on later disputes about whether a payment was timely.
Clauses the Contract Has to Contain
A financial schedule alone won’t protect either party. These clauses define what happens when a payment is late, when the property changes hands, and who is responsible for insurance and repairs.
Default and Acceleration
The default clause defines what counts as a breach: missed payments, lapsed insurance, delinquent property taxes. The acceleration clause is the seller’s remedy, letting the seller demand the entire remaining balance at once once a default occurs.5Legal Information Institute. Acceleration Clause Most contracts build in a grace period first, commonly 30 or 60 days. If the buyer can’t pay the accelerated balance, the seller either forecloses or, under a land contract, starts the process to reclaim the property.
Late Fees
State the dollar amount or percentage charged when a payment arrives after the grace period. Late fees on mortgage-type loans typically run 3% to 6% of the monthly payment, and many states cap them, so check your state’s limit. A 15-day grace period is standard for residential loans. Write both numbers into the contract so nothing is left to interpretation.
Due-on-Sale
A due-on-sale clause requires the buyer to pay off the remaining balance if they sell or transfer the property. Without it, the buyer could hand the property to a stranger who continues making payments, and the seller would be financing someone they never agreed to lend to. It is standard in virtually all mortgage-type instruments.
Prepayment
State whether the buyer can pay off the loan early without penalty. Some sellers add a prepayment penalty to protect expected interest income; others allow unlimited prepayment. Either is fine, but silence invites arguments when the buyer tries to pay ahead.
Insurance and Property Tax
Require the buyer to keep hazard insurance in force for the full loan term and to name the seller as a loss payee on the policy. If the property burns down and the seller isn’t listed on the insurance, the seller may have no claim to the proceeds despite still being owed money. Assign property tax responsibility to the buyer, and add language letting the seller pay delinquent taxes directly and roll the cost into the loan balance if the buyer falls behind.
Maintenance
Because the property is the seller’s collateral, the contract should put maintenance and repairs on the buyer, the same way a conventional mortgage does. Require reasonable upkeep and prohibit major alterations without the seller’s written consent.
What Dodd-Frank Lets You Put in the Contract
Federal law limits which loan terms a seller-financer can use, based on how many properties the seller finances per year. Two Dodd-Frank exemptions keep most individual sellers from being regulated as mortgage loan originators, and each carries conditions that directly shape the contract.6Consumer Financial Protection Bureau. 12 CFR 1026.36 – Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling
One-Property Exemption
A natural person, estate, or trust that finances only one property in any 12-month period qualifies for the lighter set of requirements:
- No negative amortization, but balloon payments are permitted.
- The interest rate must be fixed, or if adjustable, cannot adjust for at least five years and must carry reasonable annual and lifetime caps.
- The seller cannot have built the home as a contractor in the ordinary course of business.
- No formal ability-to-repay determination is required, though doing one is still prudent.
Three-Property Exemption
Any seller (including a business entity) that finances three or fewer sales in a 12-month period gets a broader exemption with stricter loan terms:
- The loan must be fully amortizing. No balloon payments.
- The seller must determine in good faith that the buyer can reasonably repay.
- Same interest rate rules: fixed, or adjustable only after five or more years with reasonable caps.
- The seller cannot have been the builder of the home.
Finance more than three sales in a 12-month window and neither exemption applies, which pushes the seller into mortgage originator licensing and full ability-to-repay compliance. A landlord unwinding a small portfolio one property at a time can cross that line without realizing it.
Signing, Notarizing, and Recording
A properly signed contract binds the parties whether or not a notary is involved. Notarization matters for a different reason: county recorder offices generally won’t accept a document for recording unless it has been notarized or formally acknowledged. Both parties should sign in the presence of a notary public, bringing government-issued photo identification. Notary fees are set by state law and are usually under $25 per signature.
Take the notarized original to the county recorder or clerk’s office in the county where the property sits. Recording puts the seller’s lien (or the land contract) into the public record, so later buyers and creditors are on notice. Skip recording and the seller risks losing priority to a later-filed lien or to a fraudulent sale to a third party.
Recording fees vary by county. Most offices charge a base fee for the first page and a smaller per-page fee after that, and a typical owner financing contract runs somewhere between $25 and $150 to record. Some counties accept documents by mail with a check and a self-addressed return envelope. The recorder assigns an instrument number and returns the original or a certified copy. Both parties should hold on to that recorded copy for any future refinance, sale, or dispute.
Tax Reporting Starts With the First Payment
Owner financing creates ongoing tax obligations that don’t exist in an all-cash conventional sale. Plan for them before the first payment is due.
The IRS treats an owner-financed sale as an installment sale whenever at least one payment lands in a tax year after the year of closing. The seller reports the income on Form 6252 every year a payment is received, including the final year.7Internal Revenue Service. About Form 6252, Installment Sale Income Each payment splits into three pieces: return of basis (not taxed), capital gain, and interest income. The seller multiplies each payment (minus interest) by a gross profit percentage to figure the taxable gain portion.2Internal Revenue Service. Publication 537 (2025), Installment Sales
Interest goes on the seller’s Schedule B as ordinary income. The seller must give the buyer their Social Security number so the buyer can claim the mortgage interest deduction on Schedule A, and if the seller receives $10 or more in interest during the year, they should issue the buyer a Form 1099-INT.8Internal Revenue Service. About Form 1099-INT, Interest Income A buyer using the property as a personal residence can deduct the interest portion of each payment, listing the seller’s name, address, and Social Security number on the return.
Consider a Third-Party Loan Servicer
Collecting payments, running the amortization schedule, holding escrow for taxes and insurance, applying late fees, and generating year-end 1099s is real work. Many seller-financed deals go sideways not because the buyer stops paying but because the seller loses track of the accounting or damages the relationship over a mishandled late payment. A third-party loan servicer handles all of it for roughly $25 to $50 per loan per month, and creates a neutral paper trail that protects both parties if the terms are ever disputed.
