800 acres off FM 407 in west Justin, eight builders, some of the most unusual amenities in DFW — and a $2,000-a-year HOA to match.
My tour of Treeline by Hillwood
Treeline is Hillwood’s third master plan in this corner of the county, after Landmark and Pecan Square. Where Pecan Square sells the front porch, Treeline sells the outdoors — a three-story gaming treehouse, a stargazing park, a fruit orchard, and miles of paved trails threaded through preserved green space.
The question I set out to answer on my tour: is all that worth a $2,000-a-year HOA?
The numbers
| Size | About 800 acres |
| Homes planned | About 2,700 at full build |
| Price range | High $300s to $600s+ |
| Lot widths | 40’ (rear entry), 45’, 50’ |
| HOA | About $2,000 a year |
| Total tax rate | 2.47% (2025), including the MUD |
| Schools | Northwest ISD — with a future elementary school site set aside inside the community |
| Location | West Justin, off FM 407 |
On those schools: a reserved site isn’t an open campus, and Northwest ISD redraws lines as new schools come online. If the assignment matters to you, ask the district about your specific address.
The eight builders
Before you click through or walk into any of these — tell me first. Registering yourself with a builder is how you lose the representation they would otherwise have paid for. Here’s why.
American Legend, Beazer, D.R. Horton, David Weekley, Highland, HistoryMaker, Pulte, and Tri Pointe. Eight builders across three lot widths means a real spread of price points inside one entrance — figure out your band before you tour.
What the HOA is paying for
- The Hideaway — the amenity center, with a resort-style pool.
- The treehouse — three stories, built for gaming.
- Sky Park, The Grove and The Nook — the themed parks: a stargazing park with an observation deck, a fruit orchard, and a library-inspired park.
- Pickleball courts, a food truck park, and an amphitheater lawn.
- Paved trails and preserved green space running through the whole community.
Takeaways from my tour
The pros
- Some of the most unique amenities in DFW.
- Lots of preserved natural space and trails.
- Eight builders at a range of price points.
- FM 156 has been expanded, so SH 114 is a quick drive.
The cons
- The HOA is on the high end.
- FM 407 traffic until it’s expanded.
- Few grocery options for now — a Walmart Neighborhood Market is coming.
- Getting to I-35 and Denton takes longer.
Who Treeline is (and isn’t) for is the last thing I cover in the video — watch the final minute for my verdict.
The tax rate, in dollars
At the 2025 rate of 2.47% before exemptions, a $500,000 home here carries roughly $12,350 a year — about $1,029 a month — in property taxes, MUD included. That’s right in the range of the other Hillwood communities. Here’s how MUD taxes work, with the other communities side by side.
The rate varies by section and every entity resets yearly — get the total for your specific section in writing before you sign.
Before you go
Eight builders don’t release on the same schedule, and sections open and close constantly. The first-visit registration rule applies here like anywhere — tell me before you go, not after.
