Backup Offers in Texas: What Every Dallas Buyer and Seller Needs to Know in 2026
Texas backup contracts use TREC Addendum 11-9 — mandatory since July 2026 — to put buyers legally in line on an already-contracted home. Here's how it works in DFW.
What Is a Texas Backup Contract, and How Does It Work?
A Texas backup contract is a legally binding purchase agreement on a home that's already under contract, governed by TREC Addendum 11-9 (updated May 2026, mandatory July 1, 2026). The backup buyer commits earnest money and an option fee immediately at signing, but performance deadlines don't begin until the primary contract terminates and the seller delivers written notice. In Dallas and across North Texas, where contract fall-through rates hit a record 13.5% in early 2026, backup offers give buyers a real second shot — and give sellers a critical safety net under an uncertain deal.

The listing said "under contract." You checked anyway, and it was everything you wanted.
Before you move on, here's something worth knowing: more than 13 percent of Texas real estate contracts terminated before closing in early 2026 — the highest rate on record. That "under contract" status is not the locked door it feels like.
Texas has a formal legal mechanism for exactly this situation: the TREC Addendum for "Back-Up" Contract. Updated in May 2026 and mandatory since July 1, it's a promulgated form that protects both sides of the deal. Here's how it actually works.
What the TREC Backup Addendum Does
The Addendum for "Back-Up" Contract (TREC Form 11-9) attaches to a full One to Four Family Residential Contract (TREC 20-17) — the same standard purchase contract used in any Texas transaction. The addendum identifies the first contract's effective date and establishes your legal position behind the primary buyer.
The moment the seller signs your backup offer, the contract becomes binding. This is not an informal agreement or a letter of intent. You are under contract.
What hasn't started yet: your performance clock. Your option period, financing contingency deadlines, the inspection window, and the closing date — none of those run until the primary deal terminates and you receive the seller's formal written notice.
The money you put in — and when
Texas requires backup buyers to deposit both earnest money and an option fee at contract execution — not when you go primary, not when the primary terminates, but right now, when you sign.
Under the 2026 addendum, payments are applied first to the option fee, then to the earnest money. The option fee is non-refundable regardless of outcome. The earnest money is protected: if the primary contract closes successfully and your backup never activates, the title company returns it in full.
Here's the part most buyers don't realize: you can withdraw from a backup position at any time before activation by delivering written notice. You lose the option fee. You get the earnest money back. A backup position isn't a trap — it's a legal option on a specific home while you keep looking at others.
Backup Contract vs. Primary Contract: The Key Differences
| Primary Contract | Backup Contract | |
|---|---|---|
| Earnest money due | At contract execution | At contract execution |
| Option fee due | At contract execution | At contract execution (non-refundable) |
| Option period starts | Execution date | When backup goes primary (seller's written notice) |
| Financing and closing deadlines | Begin at execution | Begin when backup goes primary |
| Can exit without losing earnest money? | Yes — during option period | Yes — any time before going primary |
Typical Backup Contract Deposits in DFW (2026)
| Home Price | Earnest Money (approx. 1%) | Typical Option Fee |
|---|---|---|
| $350,000 – $450,000 | $3,500 – $4,500 | $200 – $500 |
| $450,000 – $600,000 | $4,500 – $6,000 | $300 – $750 |
| $600,000 – $800,000 | $6,000 – $8,000 | $500 – $1,000 |
| $800,000 – $1,200,000 | $8,000 – $12,000 | $750 – $1,500 |
Earnest money is refundable if the backup never activates. Option fee is non-refundable once paid.
When the Backup Contract Goes Primary
When the primary contract terminates — for any reason: buyer's option period exit, financing denial, a failed appraisal, or seller default — the seller delivers formal written notice using TREC's new 2026 companion form: the Seller's Notice to Buyer of Removal of Contingency Under Addendum for "Back-Up" Contract.
The date on that notice becomes the amended effective date of your contract. Your option period clock starts. Your lender's timeline starts. Everything you negotiated in your contract begins running from that moment.
This is why your lender needs to be primed in advance. When you're in backup position, you have zero warning about when activation happens. If the primary buyer cancels during their option period, your seller's notice could arrive the same afternoon.
For Sellers: Why Accepting a Backup Makes Sense
Accepting a backup offer doesn't change your primary contract or signal weakness to your primary buyer. The first deal proceeds exactly as before.
If the primary closes, the backup terminates and the backup buyer's earnest money is returned to them. You sign nothing additional. There's no downside.
If the primary falls through — which is happening to more than 1 in 8 DFW transactions right now — you have a legally committed second buyer ready to step forward the moment you deliver written notice. No re-listing, no negotiating from scratch, no stale listing.
According to Texas REALTORS, some sellers find that an accepted backup offer actually encourages the primary buyer to stay committed and resolve issues rather than walk. The psychology shifts when a buyer knows a replacement is waiting.
One structural limit: Texas allows only one backup contract at a time on a given property.

When a Backup Offer Makes Sense for Buyers
The backup offer pays off most when the primary contract carries genuine risk. In 2026 DFW, the situations worth watching:
- The primary contract includes a financing contingency. Nationally, 27 percent of contract failures trace to financing issues — loan denials, credit changes after a job switch, appraisal shortfalls. If the primary buyer's loan hasn't been fully underwritten, the risk is real.
- The home went back to active before. A listing that came back from "pending" once already has a documented failure. It can happen again.
- Extended days on market before going under contract. When a home sat 60+ days before finally contracting, the buyer often negotiated hard and may terminate over inspection items that a more motivated buyer would accept.
- New construction competition exists at that price point in Frisco, McKinney, Celina, or Prosper. Buyers in the $450K–$600K range sometimes lock in a resale offer, then discover a builder's rate buydown makes a new build more compelling. Cancellations aren't rare in this scenario.
One figure worth calibrating: about 13.5% of contracts terminated in early 2026. That's roughly 1 in 7. If you're willing to commit earnest money with the option to walk freely before activation, those aren't unreasonable odds on a home you genuinely want.
If you're weighing a backup offer on a specific home in Allen, McKinney, Frisco, or anywhere across Collin County, schedule a private consultation with a Grey Square agent before committing earnest money. We'll look at the primary contract's timeline, the listing history, and what the odds actually look like for that specific property.
The 2026 TREC Update: What Changed
Before July 1, 2026, Texas had TREC Form 11-8 for backup contracts, but there was no standardized form for the seller's written notification when a backup moved into primary position. Agents used letters, emails, even text messages — which created disputes about when exactly the new effective date was established.
TREC's 2026 update addressed that directly. The new Form 11-9 is paired with the Seller's Notice to Buyer of Removal of Contingency — a promulgated document now required for all licensed Texas agents handling backup activations. The form definitively establishes the amended effective date of the backup contract, which is the anchor for your option period and every subsequent deadline.
If your agent is handling a backup activation with informal communication rather than the new TREC-compliant form, the effective date of your contract could be disputed — and that dispute can cost you time, money, or both.
Frequently Asked Questions
What happens to my earnest money if the primary contract closes and my backup never activates?
Your earnest money is returned in full by the title company. The only money you lose in that scenario is the option fee, which is non-refundable regardless of outcome. Confirm the option fee amount before you sign — in most DFW backup offers it's modest relative to the earnest money, but it's still a cost.
Can I keep shopping for homes while I'm in backup position in Texas?
Yes. The TREC Back-Up Addendum allows you to withdraw your backup offer at any time before it activates by delivering written notice to the seller. You forfeit the option fee but get your earnest money back. This makes the backup position genuinely flexible — you're holding a committed option on a specific home, not a promise to stop looking.
How quickly do I need to be ready to move when my backup contract goes primary?
Immediately. The seller's written notice establishes a new effective date, and your option period, financing deadlines, and closing timeline all begin running from that moment. Your lender should be briefed in advance so they're ready to order the appraisal and move the underwriting file forward without delay.
Does the seller have to accept a backup offer?
No. Accepting a backup offer is entirely the seller's decision. Some sellers actively seek them for security; others decline. If the listing agent says the seller isn't accepting backups, that's valid under Texas law — it just means you'll need to continue your search on other properties.
Who's the right agent to work with when making a backup offer on a home in Dallas, Frisco, or McKinney?
The most important things in a backup offer situation are: deep familiarity with TREC Form 11-9 mechanics, an honest read on whether the primary contract is actually likely to survive, and the logistical speed to move the moment activation happens. Paul Blair has been representing buyers and sellers across Dallas, Plano, Frisco, and Collin County for more than 22 years. If you're watching a specific home that's already under contract, schedule a private consultation — we'll talk through what we know about that contract's timeline before you commit any earnest money.
Backup contracts are one of the most powerful — and least understood — tools in the Texas buyer's toolkit. The 2026 TREC updates made the mechanics more precise and gave both buyers and sellers a cleaner legal framework. Whether you want a second shot at a home in McKinney, Frisco, or anywhere across the Metroplex, or you're a seller who wants a committed buyer waiting in the wings, understanding the backup addendum is worth your time before you need it.
