If two homes in Westlake list for the same price, do they cost the same to own? Most buyers assume yes. The Town's own numbers this month say otherwise.
On September 15, 2026, Westlake's Town Council adopted the tax year 2026 ad valorem rate at $0.185000 per $100 of value, the same headline number as the year before. The Town describes this as an effective decrease, since it sits $0.021222 below the no-new-revenue rate, and local reporting on the meeting put the average homesteaded owner's savings at roughly $442 for the year. On paper, that reads as a straightforward win for anyone who owns here.
Underneath that flat number, though, the mix moved. The maintenance and operations portion of the rate rose to $0.142206 from $0.130000, while the interest and sinking portion, which retires Town debt, dropped to $0.042794 from $0.055000. The total held steady. The composition did not. That single line item is a preview of the larger pattern in Westlake: the number a buyer sees rarely tells the whole story of what a specific address will actually cost to hold.
The Same Town, Three Different School Tax Bills
Westlake straddles Tarrant and Denton counties, and its subdivisions are zoned across three separate school districts: Carroll ISD, Keller ISD, and Northwest ISD. Each sets its own rate, and that rate does far more to determine a household's annual bill than the Town's own $0.185 does. The Town's portion is a small slice of a Westlake tax bill. The school district's portion is the largest one.
A comparison of three well-known Westlake enclaves published this spring put Carroll ISD's rate at roughly $1.0025 per $100 of valuation, against Keller ISD's rate near $1.312. On a $4 million home, that gap alone works out to roughly $12,000 a year, a number that has nothing to do with lot size, finish level, or list price and everything to do with which side of a subdivision boundary the home sits on.
| Enclave | Zoned School District | Approximate District Rate |
|---|---|---|
| Vaquero | Keller ISD | $1.312 / $100 |
| Glenwyck Farms | Carroll ISD | ~$1.0025 / $100 |
| Terra Bella | Carroll ISD | ~$1.0025 / $100 |
Westlake Academy, the Town's open-enrollment public charter, sits outside this comparison entirely. It's available as an alternative regardless of a home's zoned ISD, which means the district line on a property doesn't lock a family into a single school option. It does, however, still set the tax rate that shows up on the annual bill, whether or not a family enrolls there.
The Assessment That Isn't in the List Price
Enclave-level tax comparisons only cover part of the picture. Some Westlake subdivisions carry an additional layer that never appears in a listing's headline price at all.
Entrada sits inside a Public Improvement District, a financing structure the Town created and funded at $26.3 million in 2015 to cover the development's roadwork, parking structures, canals, and ponds. A PID assessment is separate from property tax. It's billed annually as its own line item, scaled to the size and use of each lot, and runs on a schedule set when the district was formed. In Entrada's case, that schedule stretches 30 years from origination, meaning a buyer today is stepping into an obligation that was structured over a decade ago and won't fully retire until the mid-2040s.
The district's own history is worth knowing too. A year after the PID was funded, the Town removed its original administrator, MuniCap Inc., after discovering the firm's affiliation with Entrada's developer. It's a reminder that a PID isn't a passive fee schedule. It's a governance structure, with its own oversight questions, and it's worth asking who currently administers the assessment and what the remaining balance looks like before an offer goes in.
Texas law requires a seller to disclose a PID obligation in writing before closing, so this isn't information a buyer has to dig for. It is information a buyer has to actually read, since the number often lives in an addendum rather than the listing itself.
Same Amenities, Different Utility Bill
Alongside the PID, Westlake layers in municipal utility districts, and here again the boundaries don't track with price or prestige. Solana, Entrada, Knolls at Solana, and Granada all sit inside the Trophy Club MUD, a separate taxing authority that funds water, sewer, and drainage infrastructure for those specific subdivisions. Vaquero, Glenwyck Farms, and Terra Bella don't appear on that list, which means those enclaves run on the Town's own water and sewer service rather than a MUD.
The practical difference is another taxing entity with its own line item, on top of the Town rate, the county rate, and the school district rate, for MUD-served subdivisions. None of this shows up in a comparison of median prices by neighborhood. It only shows up when someone pulls the actual tax statement for a specific address.
What to Actually Check Before You Write an Offer
A Westlake address doesn't tell you what you'll pay to own the home behind it. The subdivision does. Before comparing two listings on price alone, it's worth confirming:
- Which ISD the specific address is zoned to, not just which one is associated with the broader area
- Whether the subdivision sits inside a PID, and if so, the remaining balance and years left on the assessment schedule
- Whether utilities run through a MUD or through the Town's own utility billing department
- The full stack of what shows up on the tax statement: Town, county, ISD, and any special district, added together rather than assumed from the Town's rate alone
Two homes with the same Westlake mailing address and a similar list price can carry meaningfully different total costs of ownership once all four of those pieces are added up. That difference is often larger than anything a negotiation over the sale price will move.
A Few Direct Questions
Does everyone in Westlake pay the same property tax rate? No. The Town's own rate is uniform, but the school district rate, which makes up the largest share of most bills, varies by which of the three ISDs a specific address is zoned to.
Can I send my kids to Westlake Academy no matter which enclave I buy in? Westlake Academy operates as an open-enrollment public charter, available as an alternative to a home's zoned ISD regardless of subdivision. Enrollment availability is a separate question from which district's tax rate applies to the property.
Does a PID assessment go away when I buy the home? No. The assessment is tied to the property and continues on its original schedule. A buyer in a PID subdivision like Entrada takes on the remaining balance of that 30-year obligation, not a fresh start.
Before you compare two Westlake listings on price alone, it's worth having someone pull the actual tax and assessment picture for each address, not just the town-wide headline.
