How a Backup Offer Works in a Texas Contract

Losing a house to another buyer doesn’t have to be the end of it. Texas has a specific contract form for exactly this situation, the TREC Addendum for Back-Up Contract, and it puts your offer in line behind the accepted one without either side owing anything until the first contract falls apart.

We use this more than most buyers realize is possible. A house goes under contract, a disappointed buyer calls us wanting to walk away from the search entirely, and we tell them to hold on. If the property had multiple strong offers, or if the accepted buyer’s financing looked thin, a backup position can turn into the winning position with zero extra bidding.

How the paperwork works

The backup addendum sets a specific deadline. If the primary contract terminates before that date, whether from an option period walk-away, a failed inspection negotiation, or a financing denial, the seller notifies the backup buyer in writing, and that notice date becomes the new effective date of the backup contract. It converts to primary status without anyone re-negotiating price or terms from scratch, unless both sides agree to change something.

Here’s the sequence, start to finish:

1. Backup buyer and seller sign the TREC backup addendum with an agreed deadline
2. Both contracts sit in place, but the primary buyer and seller are the only ones with active obligations
3. If the primary contract terminates before the deadline, the seller sends written notice to the backup buyer
4. The backup contract becomes the primary contract as of that notice date, and the backup buyer’s own option period, financing timeline, and earnest money deadlines start from there
5. If the deadline passes with the primary contract still intact, the backup contract ends there, and the backup buyer gets their earnest money back

What it costs to be in backup position

You’re not obligated to close, and you’re not paying anything extra to hold the spot. What you are doing is putting up earnest money and, if the addendum calls for one, an option fee, the same as you would on any offer. If the backup contract never activates, the earnest money comes back. The option fee usually doesn’t, since it’s what compensated the seller for keeping your offer on file instead of moving on to the next buyer in line.

Why sellers take a backup offer at all

Not every seller wants one. Some worry it signals doubt about their primary buyer, or that it complicates their file for no reason. But a seller with a genuinely uncertain buyer, a stretched pre-approval, a home that hasn’t cleared an appraisal-adjacent price point, or a long option period with contingencies, has a real reason to want a second contract sitting ready. It gives them a next step instead of a relist if the deal collapses. We recommend it to sellers whenever the numbers on the primary offer leave us with real doubt.

If you’re the buyer weighing whether a backup position is worth pursuing, ask your agent specifically how many other backup offers are already in line ahead of yours, since that determines your real odds far more than the price you’re offering. And if you end up walking from a primary contract yourself, understanding how the earnest money deadline works and how long a Texas option period runs will tell you exactly when the house you’re in backup position for is likely to open up.
