Glenn Heights New Build Closing Delay: What Happens to Your Rate Lock?

If your Glenn Heights builder finishes late, your rate lock can expire before you close. The TREC new home contract lets some delays extend completion, but your lock is a separate agreement with your lender. Ask for the lock length, the extension fee, and any float-down option in writing before you sign.
The builder's rep works for the builder. Nobody in the model home is watching your lock date. That is your job, and your lender's.
Does the builder's delay extend my rate lock?
No. The construction schedule and the rate lock live in two different documents. The builder contract sets the completion and closing dates. Your lender's lock sets how many days your rate is held.
As I read TREC Form 23-20, the New Home Contract (Incomplete Construction), effective May 4, 2026, paragraph 7E lets delays from acts of God, fire, strikes, or unavailable materials push out completion, but not past the Closing Date written in the contract. Builder addenda often change these terms, so read yours line by line. The earnest money side of schedule changes is covered in how earnest money works on a Glenn Heights new build.
What does a late closing cost you in payment terms?
Freddie Mac's survey put the 30-year fixed average at 7.28% on October 1, 2026, up from 7.03% the week before (Freddie Mac PMMS). Here is what that 25 basis point move does to a $380,000 loan. The Glenn Heights median sale price was $367,257 in August 2026, according to Redfin.
| Illustration | Rate (30-year fixed) | APR | Principal and interest |
|---|---|---|---|
| Lock held at last week's average | 7.03% | 7.10% | $2,535.81 |
| Re-locked at this week's average | 7.28% | 7.35% | $2,600.01 |
| Difference | 0.25 points | 0.25 points | $64.20 a month |
That is $770 a year, or $3,852 over five years, for a delay you did not cause. Rates shown are Freddie Mac PMMS weekly averages, not quoted rates. Illustrative example, not a loan offer, rate lock, or promise to lend. APRs assume a conventional 30-year fixed loan with at least 10% down, no mortgage insurance, $1,495 in lender fees, 0 points, and 15 days of prepaid interest. Principal and interest only. Taxes, insurance, and HOA dues are extra.
Rates can also fall during a delay. A lock protects you from a rise, and what it does if rates drop depends on your lender's terms, which is why the float-down question matters.
What should you ask your lender about lock length on a new build?
Ask these before you sign the builder contract, and get the answers in writing:
- How many days is the lock, and when does the clock start?
- What is the extension fee schedule if closing slips?
- Is a float-down available, and what does it cost?
- If the lock expires, what rate do I get, and how fast can I re-lock?
Builder-affiliated lenders often package incentives with their own loan. That choice has its own tradeoffs, covered in why the builder's package is really about the lender.
Which dates in the contract decide your risk?
| Term | What to check | Who controls it |
|---|---|---|
| Completion date (paragraph 7E) | The target date and the listed delay causes | Builder |
| Closing date (paragraph 9A) | The "on or before" date and the 7-day window after objections are cured | Contract |
| Rate lock | Days held, extension fee, float-down | Lender |
| Builder incentive | Whether it expires or requires closing by a date | Builder addendum |
Disputes over delays can end up in arbitration if your contract says so. Our post on arbitration clauses in Glenn Heights builder contracts explains what that paragraph does.
Is a finished home safer than a build from the slab?
A finished home has a known completion date, so your lock matches a real closing. A home under construction carries schedule risk. If you need a firm move date, ask the builder which lots are move-in ready and what the realistic closing window is. Glenn Heights homes were taking about 79 days to sell in August 2026, up 17 days from a year earlier (Redfin), so you have time to compare finished inventory with a build. Browse what is available through Glenn Heights homes for sale.
The number to remember is $64.20 a month. A builder's schedule can cost you that much, and the builder's rep will not bring it up. Your lock terms will.
Frequently asked questions
How long is a typical rate lock on a new construction loan?
Lock lengths and extension terms vary by lender and loan program. Get the number of days in writing and compare it to the builder's estimated completion date, with a cushion.
Can the builder move my closing date?
The contract sets the closing date, and delays are handled under the completion paragraph and any builder addendum. Changes to your dates should be in writing. Ask a Texas real estate attorney if the language is unclear.
Do I lose my earnest money if I walk away over a delay?
It depends on your contract's terms and which party is in default. Read the earnest money and default paragraphs before you sign, and see our earnest money guide for how builder deposits differ from resale deposits.
What is the median home price in Glenn Heights, TX?
Redfin reported a median sale price of $367,257 in August 2026, up 0.3% from a year earlier, with homes taking 79 days to sell. Figures are based on current conditions and change monthly.
Does a builder rate buydown still apply if my closing slips?
Some builder incentives carry expiration dates or require closing by a set date. Ask for the incentive terms in writing and confirm what happens if the builder is the one who is late.
Do I need my own agent when I visit a builder model home?
The rep in the model home works for the builder. Many builders will register a buyer's agent if that agent is with you on the first visit, so confirm the registration rules before you walk in.
