How to write a promissory note for land in Texas, and why every blank is a future argument

A promissory note is a short document with a long memory. It gets signed on a pleasant closing day, filed in a drawer, and then pulled out six years later by two people who remember the deal very differently. One of them is usually you.

This article explains what goes into a promissory note on an owner-financed Texas land sale, why each part exists and where sellers get hurt. It is not a form to copy. It is also not legal advice. The note and the lien that secures it should be drafted or at least reviewed by a Texas attorney or a title company that handles seller-financed closings. Think of this as the briefing you read before that meeting.

What is a promissory note on a land sale?

A promissory note is the buyer’s written promise to pay you money. It says how much, how often, at what interest rate and by when. When you sell land with owner financing, you are the lender, and the note is the loan.

The note is only half the story. The note says the buyer owes you. A separate document, usually a deed of trust in Texas, gives you a lien on the land so you have something to enforce if payments stop. A note with no recorded lien is a promise backed by good intentions. Good intentions are lovely and almost impossible to foreclose on. Our pillar page on selling land with owner financing walks through how the two documents work together, and the post on contract for deed vs deed of trust explains why the structure matters.

What is the Who-When-What-If test?

Here is the rule of thumb for this entire article.

Every term in a note must answer three questions: Who decides it, by when, and what happens if they do not.

Call it the Who-When-What-If test. A clause that passes all three is a clause. A clause that fails one is a blank, and a blank is a future argument with a filing fee.

Suppose the note says “payments are due monthly.” Who decides which day of the month? By when does the payment count as on time? What happens on day 11 if the buyer says the check was in the mail? “Monthly” answered none of those. “On the first day of each month, with a ten day grace period, and a late fee of a stated amount after that” answered all three. Same idea, no argument.

You can run the test on any clause in any note. If you find yourself saying “well, we would work it out,” you have found a blank.

What does the note have to say about money?

This is the core of the document, and it is where most of the plain-English translation lives.

Money terms also need a tie-breaker for the unglamorous question of where each payment goes. A well-drafted note says payments apply first to fees and interest and then to principal, or whatever order the parties choose. If it is silent, you have a blank.

What do late fees, grace periods and default really mean?

This is the section a seller reads least and uses most.

Late fee and grace period. A late fee is a stated charge when a payment arrives after the grace period. The grace period is the window in which a late payment is still treated as on time. Both should be written as exact terms. Texas has rules about late charges on some loans, so ask an attorney what is permitted for your type of deal.

Default. Default is the list of things that let you act. Missing a payment is the obvious one. Good notes also name the less obvious ones, such as failing to pay property taxes, letting insurance lapse where insurance applies, or selling the land without paying you off. If something is not listed as default, you may find you cannot act on it.

Notice and cure. Before you can move on a default, the documents and Texas law may require written notice and a window to fix the problem. The note should say how notice is delivered and how long the buyer has. The exact steps depend on the structure and the land, so ask a Texas attorney. Our post on what to do when a buyer defaults covers the process in more detail.

Acceleration. This clause lets you declare the whole balance due after a default, instead of chasing one missed payment at a time. Without it, you may be stuck collecting installments on a loan that is going badly.

What about prepayment, taxes and selling the land?

These are the clauses that sound dull and decide who is happy at year five.

Prepayment. Can the buyer pay the note off early? If yes, is there a penalty, and does interest stop on the day of payoff? A seller who wants years of interest income should say so. A seller who wants out sooner should say that too. Texas may restrict prepayment penalties in some situations, so ask.

Property taxes. Somebody pays the property taxes, and it should not be a surprise. Unpaid property taxes generally come ahead of your lien, which makes this one of the most important blanks to fill. Many notes require the buyer to pay on time and show proof each year. See the post on owner financing down payment and interest rate for how risk shapes the terms.

Due on sale. This clause says that if the buyer sells or transfers the land, the balance is due. Without it, a buyer could hand your land and your loan to a stranger, and you would be collecting from someone you never screened.

Insurance and improvements. If the land has anything insurable on it, the note or lien should say who insures it. If the buyer plans to build, clear or dig, the documents should say what is allowed while you hold the lien.

What is the one-glance clause cheat sheet?

Print this and put it next to the draft. Each row shows the clause, what it means in plain English and the blank that turns into a fight if nobody fills it in.

The last row has caught more people than any clause above it. If the land is owned by two siblings or by a married couple, the right people must sign.

Why is the lien a separate document?

The note creates the debt. The lien creates your claim on the land. In Texas, owner-financed land sales commonly use a deed of trust, recorded in the county records, to secure the note. The recorded lien tells the world that the land is pledged to you until the debt is paid.

Order matters. The title company records the deed and the lien at closing, in the right sequence. Kitchen tables are wonderful places for pie and poor places for lien priority.

If you sign a note and never record a lien, you may hold a debt with no claim on the land. Ask your attorney or title company to confirm the lien is recorded and to give you copies of everything.

What does a note look like in a worked example?

This example is hypothetical, made up to show the idea, and not a form to copy.

Suppose you sell 15 acres for $60,000. The buyer pays $12,000 at closing, so the principal is $48,000. The deal calls for monthly payments over eight years.

Now watch the Who-When-What-If test at work on three clauses.

Payment date. Draft one says “monthly.” Draft two says “on the first of each month, with a ten day grace period, paid by bank transfer to the account named in the note.” Draft two answers who, when and what if. Draft one invites a debate about whether the fifteenth counts.

Taxes. Draft one is silent. Suppose the buyer skips the property tax bill for two years. The taxing units are owed money, and their claim generally comes ahead of your lien. In draft two, the buyer must pay by January 31 each year and send you the receipt, and failure to do so is a default. You notice in year one instead of year three.

Transfer. Draft one says nothing about the buyer selling the land. Suppose the buyer sells it to a cousin. In draft two, a transfer makes the balance due, so you decide whether to be paid off or to approve the cousin.

None of this took cleverness. It took filling blanks before anyone had a reason to disagree.

When should you not use owner financing at all?

A note is a long-term relationship with a stranger, with paperwork. Skip it, and consider a cash sale instead, if any of these are true:

• You need most of the money soon, for a tax debt, a probate expense, a medical bill or a move.
• You could not afford the months or years it would take to retake the land if the buyer stopped paying.
• You have no patience for tracking payments, taxes and insurance, and no budget for a servicing company.
• The land is co-owned by heirs who would have to share a note for years. See selling heirs property.
• The down payment on offer is small, so the buyer has little to lose by walking away.

Our post on owner financing vs a cash offer puts numbers beside the tradeoff.

Which parts of the note deserve the most attorney time?

You are paying for judgment, so aim it at the places where judgment matters.

1. Confirm the structure. Ask whether a note and deed of trust fit your land and your buyer, or whether another structure applies. Texas has special rules for some contracts for deed on land used as a home.
2. Check the interest and fees. Ask whether the rate, late fees and any prepayment terms are allowed for this type of deal.
3. Write the default and cure terms. Ask what must be sent, to whom, how and by when.
4. Set the tax and insurance duties. Decide who proves what, and when.
5. Confirm signers and capacity. Make sure every owner, spouse or entity representative signs correctly.
6. Check recording. Ask the title company or attorney to confirm the lien is recorded and send you the recorded copies.

If you also plan to sell the note later, tell your attorney now. A note written with clean terms and a recorded lien is easier to sell or pledge than one that reads like a napkin. We cover that in how to structure an owner-financed land sale in Texas.

What mistakes show up again and again?

• Writing the note from an internet form. Forms are written for nobody in particular, and your land is somebody in particular.
• Skipping the lien. A note without a recorded lien is a promise with no collateral.
• Treating “we trust each other” as a clause. Trust is lovely. It does not survive a death, a divorce or a new owner.
• Leaving taxes to chance. The buyer’s tax bill can become your problem quickly.
• Letting the buyer take possession before everything is signed. Sign first, then hand over the keys.

Where does a direct cash buyer fit?

We buy Texas land for cash. If you want to sell your land to us on owner-financed terms, we can talk through a note like the one you are drafting, and your attorney reviews it either way. We may be the buyer who makes owner financing unnecessary. If a cash sale would solve a tax problem, an estate problem or a deadline, you can see how it works, read about selling land without a realtor or contact us for a no-pressure look at the records. If a note really is the better fit for you, we will say so, and you should use a Texas attorney to build it.
