Is an Option Contract Legally Binding?

Yes, but only on the seller at first. Once both parties sign, the seller has to honor the option. The buyer becomes bound only after exercising it.

Is the Option Fee Refundable?

Usually not. The seller keeps the fee if you don’t exercise. Most contracts, including our template, refund it only if the seller defaults or can’t deliver clean title.

Can You Assign an Option Contract?

Yes, unless the contract forbids it. Investors often assign options to other buyers for a fee instead of closing themselves.

Does an Option Contract Need to Be Recorded?

Most states don’t require it, but you should record a memorandum anyway. Without one, a buyer who doesn’t know about your option could purchase the property and wipe out your rights.

Who Is the Optionor and Who Is the Optionee?

The optionor is the property owner who grants the option. The optionee is the buyer who pays for the right to purchase.

Option Contract in Real Estate: Free Template + Example

An option contract in real estate gives a buyer the exclusive right, but not the obligation, to buy a property at a set price within a set time. The buyer pays the seller an option fee for that right, and the seller can’t sell to anyone else until the option runs out.

You lock up the deal now and decide later. That’s the whole appeal.

Below you’ll find a free real estate option contract template, a worked example with real numbers, and the clauses I’d never sign an option without.

Our free template is a standalone option to purchase for residential property, printable and ready to sign. It includes a Memorandum of Option addendum with notary blocks, so you can record the option with the county and protect your position.

How to Use the Template

The option period you ask for depends on the seller’s timeline. That’s why I run through my questions to ask motivated sellers before I fill in a single date.

Once you know what the seller needs, fill in the form in this order:

Parties. Write the owner’s name as the optionor and your name (or your company’s) as the optionee.
Property. Add the address, parcel number, and legal description from the deed.
Option fee. Enter the amount and check whether you’ll pay at signing or through the closing agent.
Fee credit. Check whether the fee counts toward the purchase price in full, not at all, or in part.
Option period. Write the exact expiration time and date. Decide whether you get extensions and what each one costs.
Purchase price. Enter the price you’ll pay if you exercise, plus the earnest money you’ll put down after exercise.
Assignment. Check the box that lets you assign the option if you might sell it to another buyer.
Sign and record. Sign the contract, then sign the Memorandum of Option in front of a notary and record it with the county.

Don’t skip the last step. I’ll explain why further down.

What Is an Option Contract in Real Estate?

A real estate option contract is an agreement in which a property owner gives a buyer the exclusive right to buy the property at a fixed price before a fixed deadline, in exchange for a fee. The buyer can walk away. The seller can’t.

The contract uses two terms you’ll see everywhere. The seller is the optionor, and the buyer is the optionee. Because only the seller has to perform, lawyers call it a unilateral contract, and it becomes a two-sided contract once the buyer exercises the option (PrepAgent, n.d.).

Option contracts are legal in every state, but you’ll see them most in Texas, where they’re built into the standard purchase forms (Redfin, 2025). Everywhere else, you’ll usually need a custom contract like the template above.

How Does a Real Estate Option Contract Work?

You pay the seller the option fee. The option period starts. During that window, you inspect, run numbers, line up financing, or find a buyer.

Before the deadline, you make one decision: exercise or walk. If you exercise by sending written notice, the option turns into a binding purchase contract, and both sides have to close on the terms you already agreed to (Lawyers.com, 2025). If you let it expire, the seller keeps the fee and you’re done.

Option Contract Real Estate Example

Here’s a simple option contract real estate example. You pay a seller $5,000 for the right to buy a house for $190,000 anytime in the next six months. This is a hypothetical deal, but the numbers match what I’d expect on a modest single-family house.

Term	Amount
Current market value	$200,000
Strike price (your price to buy)	$190,000
Option fee	$5,000
Option period	6 months
Fee credited at closing	Yes

Now play out the three ways this can end.

You exercise and buy. You send the exercise notice in month five. At closing, the seller credits your $5,000 fee, so you bring $185,000 plus closing costs. You own a $200,000 house for $190,000.
You assign the option. You never close yourself. Instead, you line up cash buyers during the option period and assign the option to one of them for $12,000. That buyer closes at $190,000, you get your $12,000, and the seller gets the price they agreed to.
You walk away. The inspection turns up a cracked foundation, or the market drops. You let the option expire. The seller keeps the $5,000 and can sell to anyone.

That third outcome is the real price of an option. You’re paying $5,000 to avoid being stuck with a $190,000 mistake.

Option Contract vs. Option Period in Texas

In Texas, “option” usually means something different: a short termination window inside the standard purchase contract, not a standalone right to buy. The buyer pays a small fee for the right to cancel for any reason during a set number of days.

The Texas option period usually runs 7 to 10 days, and the fee usually lands between $100 and $350 (HAR, 2024). The seller never refunds that fee, and the buyer’s termination notice has to reach the seller by 5 p.m. local time on the last day (Texas Real Estate Research Center, 2025). If a buyer wants more time, they have to buy a new option period with a new fee, not a token amount (Texas Real Estate Research Center, 2025).

The template in this article is the standalone kind. If you’re buying in Texas with an agent on the state form, you’re dealing with the termination option instead.

What Should a Real Estate Option Contract Include?

A real estate option contract has to be in writing, include a fee paid to the seller, and spell out every term of the future sale. If you leave the price or the deadline vague, you may not have an enforceable option at all.

Here’s what each piece of the contract does.

Clause	What It Covers
Parties	Optionor and optionee
Property	Address and legal description
Option fee	Amount and payment timing
Option period	Exact expiration date and time
Extensions	Number, length, and cost
Strike price	Price if you exercise
Fee credit	Whether the fee counts toward price
Exercise notice	How you tell the seller you’re buying
Purchase terms	Title, closing, costs, possession
Seller’s duties	No new liens, leases, or sales
Assignment	Whether you can transfer the option
Recording	Memorandum of Option

Pay the most attention to the seller’s duties. An option does you no good if the owner takes out a second mortgage or signs a two-year lease halfway through your option period.

How Much Is an Option Fee?

For a standalone option, sellers commonly receive 3% to 10% of the property’s market value up front (Lawyers.com, 2025). That’s a lot more than the Texas termination fee, because you’re asking the seller to take the property off the market for months, not days.

I think of the fee as rent on the seller’s patience. A longer period costs more. A seller with a mortgage payment due every month will want enough to cover the wait.

The fee and the strike price are one negotiation. Working out what to offer a motivated seller means pricing both together, because a seller will often take a lower strike price in exchange for a bigger fee today.

Should You Record an Option Contract?

Yes. If the seller sells the property to someone who doesn’t know about your option, your rights end, and all you have left is a breach claim against the seller (Lawyers.com, 2025).

A Memorandum of Option fixes that. It’s a one-page notice you record with the county that tells title companies and future buyers your option exists, without making your price or fee public.

Option Contract vs. Lease Option vs. Right of First Refusal

An option contract binds only the seller, a lease option adds a rental agreement to that option, and a right of first refusal only gives you the chance to match someone else’s offer. Here’s how they line up against a regular purchase agreement.

Contract	Who Has to Perform	Typical Use
Option contract	Seller only	Investors, land deals
Lease option	Seller only on the sale	Rent-to-own homes
Lease purchase	Both parties	Rent-to-own with a firm sale
Right of first refusal	Seller, only if they sell	Tenants, partners, neighbors
Purchase agreement	Both parties	Standard sales

The lease option and lease purchase get mixed up constantly. A lease purchase commits both sides to the sale, while a lease option gives only the tenant-buyer the choice (Wikipedia, n.d.).

Lease options come up most with tired landlords, who want out of managing tenants but won’t take a discount on price.

Check your state’s rules before you write one. Texas treats a residential lease combined with an option to buy as an executory contract, unless the deal delivers the deed within 180 days (Texas Property Code, 2026). That label comes with real duties: the seller generally has to record the contract within 30 days, and the buyer can cancel for any reason within 14 days of signing (Weaver Law Firm, 2026). Illinois has separate rules for rent-to-own deals where the buyer pays in installments for a year or more and the seller keeps an interest in the property (Illinois Legal Aid Online, n.d.).

How Do Investors Use Option Contracts?

Investors use option contracts to control a property without buying it yet. You get time and a locked price, and you only spend the option fee until you decide.

Wholesaling With an Option Instead of an Assignment

Some investors use an option instead of a purchase contract when they’re wholesaling real estate, because an option doesn’t commit them to close. If the buyer they lined up backs out, they lose the option fee, not a lawsuit over earnest money.

An option is also assignable unless the contract says otherwise (PrepAgent, n.d.). That’s why the template has an assignment checkbox.

Don’t treat an option as a loophole, though. State rules on marketing a property you don’t own still apply, and whether you need a real estate license to wholesale can depend on how your state treats options.

Land and Development Deals

Land buyers use options to buy time for the slow stuff. During the option period, you can research permits, zoning, and environmental issues before you commit to the price (Adobe, n.d.). The template requires the seller to sign owner consent on those applications, which saves you a fight later.

Vacant property owners are often open to an option, because the fee pays them something on a property that’s costing them money every month.

Sellers Who Won’t Budge on Price

Sellers are more likely to agree to an option when they can’t get fair market value or the market has gone cold (LawInfo, 2024). You give them their price. They give you time.

Is an Option Contract a Good Idea?

An option contract is a good idea when you need time more than you need a discount. It’s a bad idea when a regular purchase agreement with a long inspection period would get you the same protection for less money.

For you as the buyer, the upside is control. You lock the price, you get months instead of days, and your maximum loss is the fee. The downside is that the fee is gone if you don’t buy, and a 3% to 10% fee adds up fast on a deal that doesn’t work.

For the seller, the upside is cash now and a likely sale later. The downside is that the property sits off the market, and if the price climbs during the option period, the seller doesn’t see a dime of it.

My rule is simple. If I can get the seller to accept a 30-day inspection period on a regular contract, I’ll do that and keep my money. I pay for an option when I need months, not weeks: a zoning change, a buyer who needs time to raise funds, or a seller who won’t sign anything with a firm closing date.

What Happens When an Option Contract Expires?

When an option contract expires, the seller keeps the option fee and can sell the property to anyone. You have no further rights to the property.

If you recorded a Memorandum of Option, sign a release and record it so the seller’s title stays clean. The template requires the optionee to sign one when the seller asks.

Other Real Estate Contracts

Some deals call for a different contract than an option. Here are the ones investors use most:

Final Thoughts

An option only works if you find a seller who needs flexibility. A homeowner with three offers on the table won’t give you six months for a fee.

The sellers who say yes to an option are almost always motivated seller leads, people with a reason to trade flexibility for cash now.

If you want to skip the cold lists, you can browse verified motivated seller leads on the exchange and find owners in your market who are ready to talk terms. Then print the template and bring it to the first meeting.
