How to Read a Builder Contract in Austin: What New Construction Buyers Miss and Pay For

New Construction Buyer Guide  ·  May 2026

The builder's purchase agreement is not the TREC contract you sign when you buy a resale home. It is a custom document written by the builder's legal team to protect the builder's interests — and most buyers sign it without fully understanding what they have agreed to. This post walks you through what is actually in there, what it costs when you miss it, and what you can do about it before you sign.

Most buyers who purchase new construction in Austin go through the process at least partially unrepresented on the contract side — either because they walked into a model center without an agent, because they assume the builder's sales rep is looking out for their interests, or because nobody told them that the standard TREC contract does not apply here. All three of those assumptions are expensive.

Builder contracts in Texas are not regulated forms. They are proprietary documents that vary by builder, are negotiated in the builder's favor by design, and contain provisions that would not survive in a standard resale transaction. Understanding what is in yours — before you sign it — is one of the most consequential things you can do as a new construction buyer.

Here are the ten provisions that Austin new construction buyers most consistently miss, and what each one costs when it is not understood or negotiated upfront.

1. The Earnest Money Structure

In a standard Texas resale transaction, earnest money is typically 1% of the purchase price, held in escrow, and refundable during an option period if the buyer decides to walk away for any reason. Builder contracts work differently — often very differently.

Most Austin luxury builders require earnest money of 3–10% of the purchase price at contract execution. At $2.5M, that is $75,000–$250,000. More critically, a significant portion of that earnest money — sometimes all of it — goes non-refundable immediately upon contract execution, not after an option period expires.

This means that if you sign a builder contract on a $2.5M home today and discover next week that your financing fell through, your employer transferred you to another city, or you simply changed your mind about the floor plan — you may have no legal right to recover any of that money. Read the earnest money provisions carefully and understand exactly when your deposit becomes non-refundable before you sign anything.

2. The Missing Option Period

In a standard TREC resale contract, buyers pay a small option fee — typically $100–$500 — in exchange for an unrestricted right to terminate the contract during a defined option period (usually 7–10 days). During that period, the buyer can walk away for any reason and receive their earnest money back in full.

Builder contracts almost never include an option period. Once you are under contract, you are under contract — and the exit provisions, if they exist at all, are narrow and specific. Walk away outside those provisions and you forfeit your earnest money. This is one of the most significant structural differences between a builder contract and a standard Texas resale transaction, and it is the one that costs buyers the most money when it catches them off-guard.

3. Financing Contingency Language

Builder contracts typically include a financing contingency — a provision that allows the buyer to terminate if they cannot secure financing — but the terms of that contingency matter enormously. Pay attention to:

The approval deadline. Builders set a specific date by which your financing must be approved. If your lender needs more time due to underwriting complications, that deadline does not move automatically. Missing the approval deadline can void your financing contingency and put your earnest money at risk even if your financing ultimately comes through.

The definition of "approved." Some builder contracts require a full underwriting approval, not just a pre-approval letter. Others accept a conditional approval. Know exactly what standard you are being held to — and make sure your lender can meet it within the timeline specified.

The preferred lender provision. Many builders have preferred lenders and include contract language that requires the buyer to at least apply with the preferred lender before using an outside lender. Failing to complete that application — even if you intend to use your own lender — can be treated as a contract default by some builders. Read this provision carefully.

4. The Preferred Lender Incentive Trap

Builder preferred lenders are real and the incentives they offer are often genuine — rate buydowns, closing cost credits, upgrade allowances. But the incentive is structured to benefit the builder's sales process as much as it benefits you, and the preferred lender is not always offering the most competitive terms on the open market.

The right approach: apply with the preferred lender to qualify for the incentive, simultaneously get a competing quote from your own lender, and compare the total cost of financing — not just the rate, but origination fees, buydown cost, and all-in closing costs — before you decide which to use. The incentive is worth capturing if the underlying loan terms are competitive. It is not worth capturing if you are paying for it in a higher rate or worse terms over the life of the loan.

5. The Change Order Pricing and Cut-Off Dates

Change orders — modifications to the agreed scope after the contract is signed — are a standard part of any custom or semi-custom build. What is not standard, and what most buyers do not anticipate, is how aggressively builders price them.

Builder change order markups typically run 20–30% above the underlying material and labor cost. A countertop upgrade that costs the builder $8,000 in material and installation may be quoted to you as a $10,500–$11,000 change order. This is not necessarily unreasonable — the builder is managing coordination, warranty liability, and schedule impact — but it means that changes made after contract execution are always more expensive than they appear on the surface.

More critically, most builder contracts include cut-off dates by construction phase after which certain changes cannot be made at any price. Structural changes are typically locked in before framing. Electrical and plumbing changes are locked in before drywall. Finish selections have their own cut-off calendar. Missing these windows — which is easy to do during a busy build when you are not watching the schedule — can mean living with choices you did not intend to make permanently.

6. Completion Date Provisions

This is the provision that surprises buyers most consistently — because it is the one that sounds like a commitment but almost never is.

Builder contracts typically include a projected completion date or a completion window. What they almost universally do not include is a meaningful penalty if that date is missed. Force majeure clauses — covering supply chain disruptions, weather delays, labor shortages, and permit delays — are broadly written and give the builder significant flexibility to extend the timeline without consequence.

In practice, this means that a projected 14-month build can run to 18 or 20 months with no financial recourse for the buyer. If you have sold your current home in anticipation of a specific completion date, that timeline extension becomes a very expensive problem. Understand what your recourse is if the build runs significantly past the projected close before you commit to a sale of your existing home.

7. Price Escalation Clauses

On presale and early-stage construction deals where the build timeline is long, some builders include price escalation provisions that allow them to adjust the contract price based on documented increases in material costs. These clauses are more common than they were before 2020 and more negotiable than builders sometimes present them.

If your contract includes a price escalation provision, understand the cap — what is the maximum percentage increase the builder can invoke, and what documentation are they required to provide to justify it? A well-negotiated escalation clause includes a hard ceiling on the increase and requires specific, auditable documentation of the cost increase before the builder can invoke it. A poorly negotiated one gives the builder broad discretion with limited accountability.

8. Warranty Terms and What They Actually Cover

Texas law requires builders to provide specific minimum warranty coverage on new construction. Understanding what is legally required — and what your builder's contract actually delivers — is essential before you close.

Texas statute requires:

Know who is responsible for warranty claims — is it the builder directly, a third-party warranty company, or the specific subcontractor who did the work? Some builder contracts transfer warranty responsibility to subcontractors in ways that make claims more difficult to resolve. Get clarity on the claims process before you close, not after a problem surfaces.

9. The Lien Waiver Requirement at Closing

When you close on a new construction home in Texas, you are entitled to receive lien waivers from the builder's subcontractors confirming that they have been paid in full for their work. This is not a technicality — it is a meaningful protection. In Texas, an unpaid subcontractor can file a mechanic's lien against your property even after you have paid the builder in full, if the builder failed to pay the sub. You then own a property with a lien on it that you did not create and did not know about at closing.

Require lien waivers from all material subcontractors as a condition of closing. Your title company should be coordinating this, but confirm it explicitly with your agent and your title officer before your closing date. Do not assume it is being handled.

10. The Arbitration and Dispute Resolution Clause

Many builder contracts include mandatory arbitration clauses that require disputes to be resolved through private arbitration rather than in court. This is not inherently bad — arbitration can be faster and less expensive than litigation — but it limits your legal options and the potential remedies available to you if something goes seriously wrong.

Understand whether your contract includes a mandatory arbitration clause, what the governing arbitration rules are, and whether there are any carve-outs for specific types of disputes. An attorney review of the dispute resolution provisions before you sign is worthwhile on any luxury new construction transaction — the cost of a two-hour attorney review is trivial relative to the potential cost of a dispute handled under terms you did not fully understand.

What You Can Actually Negotiate in a Builder Contract

The common misconception about builder contracts is that they are take-it-or-leave-it. They are not — at least not on the provisions that matter most. Here is what experienced buyers and agents regularly negotiate successfully:

Earnest money refundability window. Even a 5-day refundable period is meaningful protection and builders will sometimes agree to it on presale deals where they want to keep you engaged.

Closing cost contributions. Builders often have more flexibility on closing cost credits than on list price reductions, because credits do not affect the comp data on the transaction. Ask for a closing cost contribution before you ask for a price reduction.

Included upgrades. On a spec home that has been sitting, builders will sometimes add upgrade packages — appliances, landscape allowance, pool credit, extended warranty — before they will reduce the price. These are worth pursuing aggressively in a slower market.

Lender incentive terms. If you use the preferred lender, negotiate the specific terms of the incentive — rate buydown points, closing cost credit amount, and whether those terms are locked in the contract or subject to change.

Pre-drywall walk access. This should be in every new construction contract as a contractual right, not a builder courtesy. Get it in writing.

Independent inspection rights. The right to bring your own inspector at any point during construction — not just at final walkthrough — is worth negotiating for on a custom or presale deal.

Frequently Asked Questions

Do I need a real estate attorney to review a builder contract in Texas?
Not legally required — but on a luxury new construction transaction, an attorney review of the dispute resolution clause, the price escalation provisions, and the earnest money terms is money well spent. Expect to pay $500–$1,500 for a focused contract review from a Texas real estate attorney. That is an insurance policy on a multi-million dollar purchase.

Can I use my own inspector on a new build?
Yes — and you should. New construction defects are real and the builder's quality control process, however thorough, is not the same as an independent inspection. Schedule your inspector for the pre-drywall walk (to verify what is in the walls matches the spec) and for the final walkthrough before closing. Both inspections are worth the cost.

What happens if the builder goes out of business during my build?
This is a real risk on boutique new construction and one that is underestimated by most buyers. Before you go under contract, verify the builder's financial standing — ask who their construction lender is, confirm the construction loan is in place and funded, and understand how draws are managed. At closing, require lien waivers from all subcontractors to protect against unpaid claims. If the builder fails mid-build, your recourse is governed by the contract and the construction lender's position — which is why both matter.

Is it normal for a builder to require I use their title company?
Yes — many builders designate a preferred title company and some require its use as a contract condition. This is legal in Texas. The practical implication is that the title company has a long-standing relationship with the builder, which can affect how aggressively they advocate for the buyer's interests on lien waivers, survey issues, and closing discrepancies. Having your own agent review the title commitment and closing disclosure before closing is the counterbalance to this dynamic.

What should I do if I find defects at the final walkthrough?
Document everything in writing — photos, video, a detailed written punch list signed by both parties. Do not close until you have a written agreement from the builder on which items will be resolved and by what date. Items that are "we'll get to it after closing" without a written commitment and a deadline are items that may never get resolved. Leverage is highest before closing and effectively zero after you take the keys.
