Locking a New Construction Rate While Houston Rates Doubled

A resale closing happens in 30 to 45 days. A new construction closing, depending on the builder and the stage the home is at when you sign, can happen six, nine, or twelve months out. In most years that gap is a minor planning detail. In 2022, it was the difference between a 3.5% rate and something north of 6% — on the exact same floor plan, the exact same price, the exact same builder.

The 30-year fixed rate started 2022 at roughly 3.22% and had crossed 6% by June, driven by the Fed's response to inflation. By the end of the year it had touched above 7% before settling back into the mid-6s. For a buyer who signed a new construction contract in January expecting to close in July at a rate close to what they'd budgeted for, that was not a small adjustment — it was a different house, in terms of what the payment actually required.

What builders actually offered

Most production builders in the Houston area have an in-house or preferred lender, and in 2022 several of them started offering rate locks earlier in the build process than they had in prior years — sometimes locking a rate at contract signing rather than waiting until the home was closer to completion. The trade-off was usually a higher locked rate than the day's market rate, priced in as insurance against further increases. Buyers who took an early lock in the spring generally came out ahead of buyers who waited and floated, given how the rest of the year went. Buyers who floated hoping for a pullback in the fall were, for the most part, disappointed.

Float-down provisions — the option to lower a locked rate if rates fell before closing — existed with several builders' preferred lenders, but they came with fees and timing windows that were easy to misread. A float-down that only triggers within 15 days of closing isn't useful if the actual improvement in rates happens three months earlier.

What this meant for a Houston buyer specifically

For buyers under contract with builders in the Cypress and northwest Houston corridor during the back half of 2022, the practical options were limited to three: close at whatever the market rate was at closing, see if the builder's lender had a buydown program (several introduced temporary 2-1 buydowns that year specifically to keep deals from falling apart), or walk away from earnest money that in some cases was substantial.

Most buyers who stayed in their contracts did so because the home itself still made sense for their life — a relocation timeline, a school district, a specific commute — and they treated the rate as a problem to solve after closing, through refinancing when and if rates improved. That turned out to be the more durable approach than trying to time a market that wasn't cooperating.

The lesson for anyone signing a new construction contract today

Whatever the rate environment looks like when you're reading this, the structural issue from 2022 hasn't gone away: a new construction closing date is a prediction, and prediction has a rate risk nobody can fully hedge. Before signing, ask the builder's lender exactly when a rate lock becomes available relative to your estimated closing date, what a float-down actually costs and when it can be exercised, and what happens to your earnest money if the final payment no longer works for your budget. Those three answers matter more than the headline rate you're quoted on day one.
