Trinity Falls
2,000 acres in north McKinney with a 350-acre natural park along the Trinity River
Trinity Falls is a 2,000-acre master-planned community in north McKinney, west of US 75 and north of US 380, still actively building. Its defining feature is land the developer did not build on: a 350-acre natural park along the south fork of the Trinity River, with trails, woods and river frontage inside the community. It also has two amenity centers, a dog park and an on-site McKinney ISD elementary, Ruth and Harold Frazier Elementary, which opened in 2023.
Price Range
Roughly $350K – $750K across builders and phases, straddling McKinney’s citywide median sale price of about $505K (Redfin, three months ending May 2026). New construction pricing moves with incentives; ask for current comps with an as-of month.

- Miles of trails, a dog park and open space woven through the plan
- Multiple builders and price points inside one community, from entry product up to larger plans
- Quick US 75 access, which is the practical advantage over the communities further west

How Trinity Falls trades
In an actively building community, the builder is your main competition at resale, and it can offer rate buydowns and closing cost incentives that a private seller cannot match. That compresses resale prices in the phases where new inventory is still selling nearby. Earlier phases, where building has finished and the landscaping has grown in, tend to hold value better and are worth separating out when you look at community-wide statistics.
Taxes, dues and districts
North McKinney master-planned communities commonly sit inside special districts that add to the tax bill or add assessments on top of HOA dues. Do not take the community-level answer: get the tax rate for the exact address from the Collin Central Appraisal District record and ask the title company to identify any district assessment before you go under contract.
Check these before you offer
The trade-offs a listing will not mention. None of these are reasons not to buy here; they are the things worth pricing in.
- Still building. Expect construction traffic, noise and changing routes for years in the newer phases.
- Reselling while the builder is still selling nearby is genuinely harder, because the builder can buy down a rate and you cannot.
- North McKinney is a long way from the Tollway employment corridor. The US 75 commute is fine until it is not.
- The community is large enough that two homes in it can have quite different daily experiences depending on which amenity center and which entrance they use.
- Check the tax rate and any special district assessment for the specific phase, not for the community as a whole.
