Real Estate Promissory Note: What Sellers Need in the Note
A real estate promissory note is the buyer's written promise to repay the purchase price over time: the amount owed, the interest rate, the payment schedule, the maturity date and the consequences of default. In seller financing, the buyer signs the note in your favor, and a separate deed of trust or mortgage pledges the property as security. The note is the debt; the security instrument is what lets you take the property back if the debt is not paid.
For a seller, the note is also the tax document that matters most. The IRS calls it your installment obligation, and its terms decide when your gain is taxed and whether any of it is recharacterized as interest.
Promissory note vs mortgage vs deed of trust
People search these terms as if they were alternatives. They are not. A seller-financed sale uses a note plus one security instrument.
| Promissory note | Mortgage | Deed of trust | |
|---|---|---|---|
| What it is | The promise to pay | A lien on the property securing the note | A lien on the property securing the note, held through a trustee |
| Parties | Buyer (maker) and seller (payee) | Buyer (mortgagor) and seller (mortgagee) | Buyer (trustor), seller (beneficiary) and a neutral trustee |
| Recorded? | Usually not | Yes, in the county records | Yes, in the county records |
| Foreclosure path | Not applicable on its own | Usually judicial (through a court) | Usually nonjudicial (trustee's sale under a power of sale) |
| Where common | All states | For example, New York and Florida | For example, California and Texas |
Deed of trust vs mortgage is mostly a state-law question. Nonjudicial foreclosure under a deed of trust is generally faster and cheaper than a court foreclosure, but each state sets its own notice periods and borrower protections, and some states restrict whether a lender can pursue the borrower personally after foreclosure. Your real estate attorney or title company will use the form customary in your state.
A land contract or contract for deed is a different structure: the seller keeps title until the buyer pays in full, and there may be no separate note at all. That structure has its own risks and remedies.
What a seller-financed promissory note must say
This is the anatomy of a note, clause by clause. The business terms (price, rate, term, balloon) are covered in seller financing note terms; here the focus is on what each clause does for you as the holder.
| Clause | What it does | Why the seller cares |
|---|---|---|
| Parties and date | Names the maker(s) and the payee | Every buyer and co-buyer should sign; if the buyer is an entity, add a personal guaranty |
| Principal amount | The amount financed | Should match the purchase agreement and closing statement exactly |
| Interest rate and accrual | Rate, how it accrues (for example 30/360 or actual/365), when it starts | Must be at least the applicable federal rate for tax purposes |
| Payment schedule | Amount, due date, first payment date, where to pay | Clear dates make default provable |
| Application of payments | Order: late fees, then interest, then principal | Prevents disputes and keeps your interest and principal split clean for tax |
| Maturity and balloon | When the unpaid balance is due | Sets the year most of your deferred gain is taxed |
| Prepayment | Whether early payoff is allowed, and any premium | An early payoff accelerates your gain into that year |
| Late charge and grace period | Fee and days before it applies | Must comply with state limits and, for owner-occupied homes, consumer rules |
| Default and acceleration | What counts as default, and your right to call the whole balance due | The core remedy clause |
| Due-on-sale / transfer | Balance due if the buyer sells or transfers | Stops a stranger from taking over your note |
| Security reference | Identifies the deed of trust or mortgage that secures the note | Ties the debt to the collateral |
| Default interest and costs | Higher rate after default, attorney fees and collection costs | Shifts collection costs to the buyer |
| Waivers and governing law | Presentment, notice waivers, state law | Standard, but state-specific |
| Signatures (and notary if required) | Execution | Keep the signed original; it is the enforceable instrument |
Keep the original. The person who holds the signed original note generally has the right to enforce it, and a note buyer or a court will want to see it. Store it like a stock certificate, and give your estate plan instructions on where it is.
Consumer rules when you finance a home
If the buyer will live in the property, federal consumer lending rules may apply to you. Regulation Z provides limited exclusions from the loan originator rules for sellers who finance a small number of properties in a year, with conditions on the loan terms (12 CFR 1026.36(a)(4) and (5)). State licensing and usury laws also apply. We cover these in the seller financing addendum article and in seller financing a home. Have a real estate attorney draft or review a residential note.
How the note is taxed
The note does not change what you owe; it changes when.
Interest is ordinary income every year you receive it. It is portfolio income, so passive losses cannot offset it (Temp. Reg. §1.469-2T(c)(3)), and it counts toward the 3.8% net investment income tax. If the buyer uses the home as a residence, you report the interest on Schedule B with the buyer's name, address and SSN. See seller financing interest income.
Principal carries your gain at your gross profit percentage under the installment method (§453; IRS Pub. 537). Depreciation recapture is the exception: it is taxed in the year of sale no matter what the note says (§453(i)).
The rate floor. If the note's rate is below the AFR for its term, §483 or §1274 recharacterizes part of the principal as interest, lowering your gain and raising your ordinary income. See imputed interest.
Selling, pledging or forgiving the note is a disposition that can trigger the remaining gain (§§453B, 453A(d)). See early payoff, default and selling the note.
Simple example: one payment, split three ways
Simple example. Assumptions: you sell a rental for $500,000 with $100,000 down and a $400,000 promissory note at 7%, 30-year amortization, monthly payments. Your adjusted basis plus selling costs is $200,000 and there is no depreciation recapture, so your gross profit percentage is 60% ($300,000 gain divided by $500,000 contract price).
The monthly payment is $2,661.21. In year one the buyer pays:
| Part of year-one payments | Amount | Tax treatment |
|---|---|---|
| Interest | $27,871 | Ordinary income |
| Principal: gain (60%) | $2,438 | Long-term capital gain |
| Principal: return of basis (40%) | $1,625 | Not taxed |
| Total paid | $31,934 |
Early in an amortizing note, almost every dollar is interest. That is normal, and it is why the rate you set matters as much as the price. Run your own figures in the calculator.
Common mistakes on seller-financed notes
- Using a generic online form that does not match your state's foreclosure law or your deed of trust.
- A note with no security instrument, or one that was never recorded. An unrecorded lien can lose priority to later creditors.
- Only one spouse or one member signing when both are buyers.
- A rate below the AFR to "help the buyer," which creates imputed interest for you.
- No due-on-sale clause, so the buyer can transfer the property and leave you with a stranger's credit.
- Losing the original, which complicates enforcement, sale or payoff.
Bottom line
A real estate promissory note is the promise to pay; the deed of trust or mortgage is the security that backs it. For a seller, a well-drafted note with a recorded security instrument, a rate at or above the AFR, and clear default and due-on-sale clauses protects both the collateral and the tax deferral. Have a local attorney draft it and your CPA review the tax terms before closing.
Questions to ask your CPA
- Does my note's rate meet the AFR for its term, and which month's rate applies?
- What is my gross profit percentage, and how much of each year's payments will be taxable gain?
- Is any of my gain depreciation recapture that is taxed in the year of sale anyway?
- If the buyer occupies the home, what do I report on Schedule B and what TIN exchange is required?
- What happens to the remaining gain if the buyer prepays, or if I later sell or pledge the note?
