The option period is a short, paid window in which you can walk away from a Texas home purchase for any reason at all and get your earnest money back. You buy it with an option fee, and on the current One to Four Family Residential Contract (Resale) it lives in Paragraph 5 — not Paragraph 23, where a lot of older guides still point you.
Honestly, this is the most important paragraph in the whole contract for a buyer, and it is the one most people sign without reading. It is also unforgiving: the form says time is of the essence and that strict compliance with the time for performance is required, which in plain English means a day late is the same as never. If you are buying your first home, read this alongside my first-time home buyer guide — the money mechanics there and the clock mechanics here are the two things that actually decide how the deal feels.
Here is how the paragraph is laid out, and where each piece bites.
💵 1. What the option fee actually buys
Paragraph 5B is the whole deal in one sentence: for nominal consideration and your agreement to pay the option fee within the time required, the seller grants you the unrestricted right to terminate this contract by giving notice of termination to the seller within an agreed number of days after the Effective Date. That phrase — unrestricted — is doing a lot of work. You do not need a bad inspection. You do not need a reason at all.
Two blanks on the form decide what that right is worth: the number of days, and the dollar amount of the fee. Both are negotiated. There is no statutory default for either one, so anyone quoting you a standard option fee or a standard number of days is describing a local habit, not a rule. The current form is TREC No. 20-19, effective July 1, 2026, and the Texas Real Estate Commission describes it as the most frequently used contract form in the state. License holders are required to use it.
⏱️ 2. The clock: 3 days to pay, 5 p.m. to quit
Under Paragraph 5A you have 3 days after the Effective Date to deliver both the earnest money and the option fee. Both are made payable to the escrow agent, and the form lets you pay them separately or combined in a single payment. Whatever the escrow agent receives gets applied first to the option fee, then to the earnest money, then to any additional earnest money — so a short payment eats into the wrong bucket in exactly the order you would not want.
Your termination notice has its own deadline, and it is stricter. Notices under Paragraph 5 must be given by 5:00 p.m. local time where the property is located, on the date specified. Here is the trap worth circling: Paragraph 5A extends the deadline to the next business day when the last day to deliver money falls on a Saturday, Sunday or legal holiday. That extension does not reach the termination notice in 5B. A Sunday option deadline is a Sunday option deadline.
📝 3. How to terminate without wrecking it
Terminating is an act of paperwork, not a phone call. Paragraph 21 requires all notices from one party to the other to be in writing, and they are effective when mailed, hand-delivered, sent by overnight courier or transmitted electronically. TREC publishes a form for exactly this — Notice of Buyer’s Termination of Contract, form 38-8 — and using it removes any argument about whether what you sent counted.
If you give that notice in time, the split is clean: the option fee is not refunded and the escrow agent releases any option fee still being held to the seller, and any earnest money is refunded to you. That is the trade. You paid for the right to change your mind, and changing your mind costs you the fee and nothing else.
🔎 4. What to pack into the window
Paragraph 7A gives you the right to have the property inspected by inspectors you select, licensed by TREC or otherwise permitted by law to make inspections. One detail people miss: hydrostatic testing of the sewer lines has to be separately authorized by the seller in writing, so if you want it, ask early rather than on day six.
Work backwards from the 5 p.m. deadline, not forwards from signing. The inspector needs a slot, the report needs a day, specialists need booking after the report, and your lender needs time to confirm what it is actually willing to do. If any of those four steps slips, the one thing that does not slip is the clock. When a repair conversation needs more room than the window allows, the fix is a written amendment — TREC form 39-11 — agreed before the option period ends, not an informal promise after it.
🚪 5. Three other exits people forget
Missing the option deadline is bad. It is not always fatal, because the contract and state law carry narrower exits of their own.
The seller’s disclosure notice. Texas Property Code Section 5.008 requires a seller of residential property of not more than one dwelling unit to deliver that written notice on or before the effective date of the contract. If the contract is signed without it, the statute lets the purchaser terminate for any reason within seven days after receiving the notice, and Paragraph 7B of the contract says that if you never receive it you may terminate at any time prior to closing. There are carve-outs — foreclosure sales, bankruptcy trustees, and estates administered by a fiduciary, among others — so it does not apply to every transaction.
Financing. If your deal uses the Third Party Financing Addendum (form 40-11), Paragraph 2A lets you terminate within an agreed number of days after the Effective Date by giving the seller notice of termination and a copy of a written statement from the lender setting out the reasons for its determination. Do that and the earnest money is refunded to you. Note the second half of that requirement — a lender letter, not just your word.
Never paying the fee. This one cuts against you. Paragraph 5D says that if no dollar amount is stated as the option fee, or you fail to deliver it in time, you simply do not have the unrestricted right to terminate under Paragraph 5. A blank line or a late payment quietly deletes the protection you negotiated for.
🏗️ 6. New builds and condos play by other forms
The resale contract states plainly that it is not for use for condominium transactions, new homes being sold by a builder, or farm and ranch properties. In Montgomery County, where a large share of what I show is new construction, that matters more than it sounds.
TREC does promulgate new home contracts, and the New Home Contract (Completed Construction), form 24-20, carries its own Paragraph 5B termination option that works the same way. But a builder writing on its own paper is not using a TREC form at all, and nothing obliges that paper to contain an option period. Read it as its own document before you assume the window exists. My new construction guide covers what else changes when the seller is a builder.
One honest caveat. I am a REALTOR®, not a lawyer, and the contract itself says TREC rules prohibit brokers and sales agents from giving legal advice. Everything above is what the current forms and the statute say, read in plain English. Forms get revised — this one changed on July 1, 2026 — and your specific deal may have addenda that move these deadlines. For an interpretation of your contract, talk to a Texas real estate attorney.
In my experience: The option period is a stressful time in my experience because making sure everything is checked, verified and acceptable to my buyers in a 7- to 10 day-period. I make sure we already have an inspector and insurance person on deck so we get numbers back quickly once under contract; HOA transfer fees are a gotcha. They can be a lot more than you think, so I call the HOA; all their information is public at hoa.texas.gov. So many times I have had clients go under contract and walk away because of things discovered during the inspection, and paying a couple hundred dollars to find a potentially thousands-of-dollars problem is worth the time and money.

❓ Quick answers
How long is the option period in Texas?
There is no legal default. The number of days is a blank the buyer and seller fill in on the One to Four Family Residential Contract (Resale), TREC form 20-19, and it runs from the Effective Date of the contract. The option fee is a blank too, not a set amount. Paragraph 5B grants the buyer an unrestricted right to terminate by giving notice of termination to the seller within that number of days, and notices under that paragraph must be given by 5:00 p.m. local time where the property is located on the date specified.
Do I get my option fee back if I terminate?
No. If the buyer gives notice of termination within the time prescribed, the option fee is not refunded and the escrow agent releases any option fee still held to the seller, while any earnest money is refunded to the buyer. The option fee and the earnest money are two different payments. Under Paragraph 5A of form 20-19 both are made payable to the escrow agent and delivered within 3 days after the Effective Date, and the option fee is credited to the sales price at closing if the sale goes through.
What happens if I miss the option period deadline?
You lose the unrestricted right to walk away. Paragraph 5E says time is of the essence for that paragraph and that strict compliance with the time for performance is required, and the weekend and legal holiday extension in Paragraph 5A applies to delivering the money, not to the termination notice. You may still have narrower exits depending on the deal, such as the financing provision in the Third Party Financing Addendum or the seller disclosure notice right in Paragraph 7B, but each one carries its own conditions.
