Where are new homes being built in McKinney?

Trinity Falls is a 2,000-acre Johnson Development community near US 75 and US 380. It has a 350-acre natural park on the East Fork of the Trinity River. It sits in McKinney's ETJ (the zone just outside city limits). So it gets city water but not city trash service.

Farther north, the City approved the Honey Creek Municipal Management District (MMD) in September 2024. Plans call for 200 acres of open space, 30 miles of trails and three amenity centers.

How does buying from a builder work?

The model-home sales agent works for the builder. Bring your own agent to your very first visit, or register your agent before you walk in. Many builders require it on that first visit.

Texas has state-issued new home contract forms for homes under construction and finished homes. But many builders use their own contract. Read it with your agent before signing. Look closely at the finish date, delay terms and how upgrade deposits are handled.

Builders often like to keep the base price and offer upgrades or closing-cost help instead. A deal tied to the builder's lender can be real money. Still, compare it with at least one outside loan estimate.

Which inspections should you schedule on a new McKinney home?

Hire your own inspector even though the home is new. Book a pre-drywall inspection while framing, wiring and plumbing are visible. Then book a final inspection before closing. Book one more check before the builder warranty ends, and keep every warranty paper.

What are MUD, PID and MMD taxes in McKinney?

A MUD is a district that builds water, sewer and drainage. It repays its bonds with its own tax. A PID repays improvements through a yearly assessment. McKinney's Special Financing Districts page also covers MMDs such as Honey Creek.

The seller must give you a written notice before you sign on a home in a MUD or PID. Add every district to your budget in the mortgage calculator. Read property taxes in McKinney for the full bill. You can also browse all McKinney homes for sale.

Common questions

Do I need my own agent to buy a new home in McKinney?

It is not required, but the builder's sales agent represents the builder. Many builders require your agent to come on the first visit to be counted. Your own agent can review the contract, deals and special-district notices with you.

Is Trinity Falls inside McKinney city limits?

No. Trinity Falls is in McKinney's extraterritorial jurisdiction (ETJ). Homes get city water, but the City's trash service is for homes inside city limits. Ask the builder for every special-district notice and the current rates.

What is the Honey Creek MMD?

It is a municipal management district (MMD) the City approved in September 2024. It covers a large growth area in north McKinney. An MMD can levy a tax or assessment to pay for improvements. Ask for the district's current rate and how long it applies.

Can Mariela move fast on a quick-move-in home?

Yes. Finished and nearly finished homes can close quickly, and Mariela works at your pace. She can review the builder contract and book a final inspection on a short timeline.
