Almost every resale home in North Texas is bought on the same piece of paper: the Texas Real Estate Commission's One to Four Family Residential Contract (Resale), form 20-19. Buried in Paragraph 5 of that contract is the single most useful right you have as a buyer — and it expires on a clock that starts the day you go under contract.
Most buyers we meet understand they have "an option period." Far fewer know exactly when it starts, exactly when it ends, or how little room is left for a decision once the inspection, the contractor bids, and the negotiation are all stacked inside it. This guide is the timeline we wish every buyer had before they signed.
What the option period actually gives you
Paragraph 5 of the TREC contract is titled Termination Option. In exchange for an option fee, the seller grants the buyer what the contract itself calls an unrestricted right to terminate. That language matters: you do not need to cite an inspection finding, a failed appraisal, or any reason at all. If you give notice in time, you are out.
The mechanics, straight from the form:
- The option fee and your earnest money are due within 3 days after the Effective Date. If that third day lands on a Saturday, Sunday, or legal holiday, the delivery deadline extends to the end of the next business day.
- If you do not deliver the option fee on time, you do not have the unrestricted right to terminate. The contract says this plainly. Miss it and Paragraph 5 stops protecting you.
- The option fee is not refundable — but it is credited toward the sales price at closing if you go through with the purchase.
- Your earnest money is refunded if you terminate properly inside the option period.
- There is no standard length. The number of days is a blank on the form, filled in by negotiation. In DFW it is commonly somewhere around a week, but it is whatever your contract says — read it.
The deadline is 5:00 p.m., not midnight
This is the detail that costs people money. Notice of termination must be delivered by 5:00 p.m. local time where the property is located on the final day of the option period. Not end of day. Not before you go to bed.
Plan backward from 5 p.m. If your option period ends on a Friday, your real deadline is Friday afternoon during business hours — which means your decision has to be made Thursday night at the latest, and your inspection has to be done well before that.
A realistic day-by-day timeline
Here is how a seven-day option period actually plays out when it goes well. Adjust for your own contract length.
- Day 0 — Effective Date. The contract is executed. Your clock is running. Book your inspection today, not tomorrow.
- Day 1 — Deliver the option fee and earnest money. Do not let this drift toward the 3-day limit. Confirm the escrow agent received it.
- Days 1–2 — Inspection happens. Earlier is strictly better. Every day you wait is a day removed from the negotiation end of the process.
- Day 2 — Report in hand. This is where same-day delivery changes the math. A report that arrives the evening of the inspection instead of two days later gives you back two full days of leverage.
- Days 3–4 — Specialist follow-up and bids. Anything the report flags for a licensed trade — foundation, HVAC, roof, electrical — needs a contractor to put a number on it. This is the step that runs long, because you are now on someone else's calendar.
- Day 5 — Repair negotiation. Your agent drafts an amendment with specific, priced requests. Vague asks get vague answers; documented ones get paid.
- Days 6–7 — Seller response and your decision. The seller is not obligated to agree to anything. If you cannot reach terms, your Paragraph 5 right is what lets you leave with your earnest money.
Notice how little slack there is. A report delivered on day four leaves essentially no time for bids, which means no time for a credible negotiation — and buyers in that spot end up either accepting unknown risk or terminating out of caution.
Why we deliver reports the same day
The compression above is the entire reason Guardian guarantees a same-day report, in your inbox before 10 p.m. on the day we inspect. It is not a convenience feature. In a seven-day option period, a two-day report turnaround consumes nearly 30% of your decision window, and it consumes it at the worst possible point — before you can start getting bids.
It is also why every inspection includes thermal imaging, a WDI report, foundation elevation measurements, and an irrigation check by default. Each of those is a finding you would otherwise discover late, by scheduling a separate specialist, on a clock you cannot pause. Bundling them into the first visit is how the timeline stays survivable.
Add-ons that need to be scheduled up front
A sewer scope is the clearest example. Sewer lines are not part of a standard inspection, and in older parts of Dallas, Denton, Richardson, and Carrollton, cast iron drain lines are common enough that skipping the camera is a real gamble. Root intrusion and pipe deterioration are invisible from inside the house, and a repair can run well into five figures.
Book it at the same time as the inspection rather than as a reaction to the report. Discovering on day five that you want a sewer scope usually means you do not get one.
If you need more time
Because the option period length is negotiated rather than fixed, it can also be extended — but only by written agreement with the seller, typically for an additional fee, and only if you ask before it lapses. Sellers in a competitive situation often decline. Treat an extension as a fallback you may not get, not as part of the plan.
The more reliable strategy is simply to start early. Inspectors in DFW book out fastest on weekends and at month-end, when closings cluster. If you know your contract is coming together, call before the ink is dry.
What this means practically
Three things determine whether your option period does its job: how fast you book, how fast the report lands, and how completely that first visit covers the house. You control the first one. Choosing an inspector determines the other two.
For reference, TREC publishes the Standards of Practice that define what a Texas inspection must cover, and the Consumer Protection Notice explaining your rights. Both are worth ten minutes before you hire anyone.
