If you are shopping for new construction in Texas, you will quickly run into two very different purchase tracks: a spec home that is already built or nearly complete, and a to-be-built home that exists only on paper until you sign. Both are sold by builders. Both are brand-new. But they work differently in almost every other way that matters — timeline, cost, customization, and risk.
Here is a plain-language breakdown of what each type means for DFW buyers in 2025.
What Is a Spec Home?
A spec home (short for "speculative home") is a property a builder constructed without a specific buyer in mind. The builder picks the floor plan, lot, and finishes, starts building, and sells the home once it is complete or close to it.
When you tour a spec home, what you see is largely what you get. Countertops, flooring, cabinet colors, and fixtures are already chosen. Some builders allow minor substitutions if the home is still under construction — for example, swapping carpet for hard flooring in the primary bedroom — but structural changes are typically off the table.
Typical timeline: 30 to 60 days to close, similar to a resale purchase.
Who it suits: Buyers on a tight timeline, those relocating to Texas, or anyone who does not need to make design decisions.
What Is a To-Be-Built Home?
A to-be-built home starts with you selecting a lot and a floor plan from the builder's library. You then visit the design center and make choices: elevation, exterior finishes, kitchen package, flooring, fixtures, and any structural options the plan allows (bonus room, media room, extended patio, etc.).
After you finalize your selections and sign the contract, the builder breaks ground. Construction typically takes several months, and weather, supply chains, and permit backlogs can push that estimate out.
Typical timeline: Approximately 6 to 12 months from contract to close, though this varies by builder and market conditions.
Who it suits: Buyers who want a home tailored to their preferences and are not in a rush.
How Costs Compare
The purchase price of a spec home often reflects finishes the builder has already paid for. You may be paying for upgrades you did not choose and would not have selected. On the other hand, builders sometimes discount spec inventory — especially homes that have been sitting — to move product before the end of a quarter or fiscal year.
With a to-be-built home, you start at the base price and add upgrades at the design center. It is easy to overspend here. Builder design centers are professionally staged to encourage upgrades, and it is common for buyers to add tens of thousands of dollars above the base price before realizing how quickly costs accumulate.
In both cases, the builder's contract is typically the builder's own document — not the Texas standard forms managed by the Texas Real Estate Commission (TREC) or promulgated by Texas REALTORS®. That means fewer consumer protections by default, and it is one reason having a REALTOR® review the contract matters.
The Option Period and Inspection Differences
In a standard Texas resale transaction, buyers typically negotiate an option period — a defined window during which you can terminate for any reason, protected by the TREC-promulgated One to Four Family Residential Contract. Builder contracts are different.
For spec homes, inspections work similarly to resale: you hire a licensed Texas inspector, conduct a walk-through, and submit a punchlist to the builder before closing. Builders typically complete cosmetic repairs but rarely renegotiate price based on inspection findings.
For to-be-built homes, most builders offer a pre-drywall inspection and a final walk-through. You can also hire an independent inspector at either stage, and it is generally worth the cost. Structural issues are far easier — and cheaper — to catch and fix before walls are closed.
Financing Considerations
Both purchase types use standard mortgage products: conventional, FHA, VA, and USDA loans are all available for new construction, depending on the property and buyer qualifications. However, lenders treat them differently.
For spec homes that are complete, you finance the home like a traditional purchase. For to-be-built homes, some buyers use a construction-to-permanent loan that covers the build period and converts to a standard mortgage at closing. Others simply lock a standard mortgage once the home nears completion. Builder-preferred lenders sometimes offer rate buy-downs or closing cost credits as incentives — always compare those offers against outside lenders before committing, as the Consumer Financial Protection Bureau advises buyers to shop at least three mortgage options.
Which One Should You Choose?
Neither option is universally better — it depends on your situation. If you need to move in within 60 days, a spec home is the practical choice. If you have flexibility and care about the details of your home's finishes and layout, a to-be-built home gives you more control over the outcome.
In the DFW market specifically, both spec and to-be-built inventory exists across most active master-planned communities. Visiting a model home is free, but as noted, registering your buyer's agent before that first visit is essential to protect your representation rights under TREC rules.
