Westlake's Tax Rate Is One of the Lowest in Texas. The Math Still Isn't What You Think.

How does a town with some of the highest home prices in the Metroplex also run one of the lowest municipal tax rates in Texas? That question comes up often enough with clients comparing Westlake against Southlake, Colleyville, and other DFW luxury addresses that it deserves a straight answer, because the rate itself is real, but the conclusion most buyers draw from it is not quite right.

Town council has kept Westlake's own tax rate near the bottom of the state for years running. A recent adopted rate came in at $0.16788 per $100 of assessed value, with the town describing it as continuing a long-running practice of holding one of the lowest rates in Texas. A separate hearing notice from the town shows a proposed rate of $0.18500 per $100 the year before that. Either number, set against the roughly 2 to 2.5 percent combined effective rate that's typical across most Texas metro counties once school, county, and city levies are added together, looks like a rounding error.

That comparison is the trap. The $0.168 to $0.185 figure is only the town's own slice of the bill. It is not the whole thing.

Where the Advantage Actually Comes From

Westlake's town rate stays low because the town's tax base is not built primarily on rooftops. Charles Schwab's global headquarters, Deloitte University, and the Solana office park all sit inside Westlake's town limits, and together they carry an outsized share of the taxable value on the tax roll. Office campuses of that scale generate enormous assessed value while placing far less demand on municipal services than an equivalent value in single-family subdivisions, since they don't add students to a school system or traffic to a residential street grid the way rooftops do. That imbalance, a small resident population sitting next to a very large commercial base, is what lets the council set a nominal rate this low without shorting the town's budget.

It is a genuine structural advantage. It is also one that shows up on exactly one line of a homeowner's total bill.

What the Town Rate Doesn't Cover

School district and county taxes apply on top of the town's rate, and neither is discounted by Westlake's commercial base the way the town levy is. Those layers are assessed against the value of the home itself, and Westlake homes carry some of the highest values in the region.

Property tax data aggregator Ownwell puts Westlake's effective combined rate, meaning town, county, and school taxes together, at roughly 1.25 percent of assessed value. That's meaningfully below the Texas state median of about 1.67 percent, and it's the number that actually reflects the corporate tax base doing its job. But Ownwell also lists Westlake's median annual tax bill at $37,093, which is more than fifteen times the national median bill of $2,400. The rate is favorable. The dollar amount is not small. Both things are true at once, because the base being taxed is a multimillion-dollar home, not a median American house.

The way to read that table: Westlake genuinely undercuts the state average on the combined rate. It does not undercut the state average on the check you write, because the home values are doing more work in that equation than the rate is.

The Price Swings That Look Like Trends

The same small-sample effect shows up in Westlake's sale price data, and it's worth understanding before anyone treats a headline number as a market signal.

In July 2026, Westlake homes sold for a median price of $3.94 million, with 54 homes changing hands that month. Look instead at the three months ending May 2026, and the median jumps to $5.1 million, up 39.1 percent year over year, on just 13 total sales. That is not a market repricing itself in a season. That is a market so thin that one or two ultra-high-value estate closings can swing the median by seven figures, simply because there are so few transactions to average against.

Days on market tells a similar story. The citywide median sat around 200 days over the three months ending April 2026, a number that on its own suggests a market where nothing moves. But recent individual closings in that same window sold in 41, 97, and 102 days. A handful of listings sitting unsold for a long stretch, in a market with only single-digit monthly sales, is enough to pull the median toward "slow" even while correctly priced, well-positioned homes are still trading in under three months.

The Neighborhoods Behind the Number

Westlake's inventory is genuinely small, and it's worth knowing what's actually available across the town's gated communities before assuming the headline median describes any specific address:

• Vaquero — guard-gated around a Tom Fazio-designed golf course, with recent sales landing in the mid-single-digit millions.
• Entrada — a Mediterranean-inspired community with a lower entry point than Vaquero, showing 33 active listings and a median list price near $1.8 million as of July 2026, part of a build-out of 322 total platted units with dozens still under construction.
• Granada and Quail Hollow — both mid-build, contributing to the town's ongoing pipeline of new construction permits.
• Knolls at Solana — a smaller, newer section still filling in.
• Ventanas — a newly approved 51-home gated community on 15.3 acres, with infrastructure work that began in 2025, representing the next meaningful wave of supply the town has approved.

That range, from Entrada's roughly $1.8 million entry point to Vaquero's multimillion-dollar estate sales, is a reminder that "the Westlake median" is really an average across communities with very different price points and very different buyers.

What This Means If You're Comparing Markets

The corporate tax base behind Westlake's low town rate is real and durable. It is not going anywhere as long as Schwab, Deloitte University, and Solana remain anchored inside town limits, and that gives Westlake a legitimate, lasting edge on the combined effective rate compared to towns without a commercial base of that scale.

But that edge lives inside the total bill, not on top of it. Before comparing a Westlake property against a similarly priced home elsewhere in Southlake, Colleyville, or another DFW luxury market, pull the actual combined tax bill for the specific parcel, not just the town's advertised rate. School district and county taxes are layered on top regardless of address, and they will account for most of what ends up on the bill at these price points. The town rate explains part of the math. It does not explain all of it.

A Few Questions Worth Asking

Does Westlake's low tax rate mean I'll pay less than a similarly priced home in a neighboring suburb? Possibly, on the town's own portion of the bill. The county and school district layers apply everywhere and aren't discounted by Westlake's commercial base, so the honest comparison is the full combined bill on a specific parcel, not the headline town rate.

Why did the median sale price jump nearly 40 percent in a few months? With well under 20 total sales in the relevant window, a single high-value estate closing can move the citywide median more than it would in a market with hundreds of monthly transactions. Treat any short-window percentage change in Westlake as a reflection of which specific homes sold, not a repricing of the market.

Is 200 days on market typical here? It's the citywide median in a market this thin, but recent individual closings in 41 to 102 days show that a correctly priced, well-positioned home can still move well inside that average.
