Beyond The 78746 Median: What A Westlake Address Actually Buys In 2026

Before a serious buyer signs anything on this side of MoPac, one call matters more than the inspection scheduler or the lender: the one to Travis Central Appraisal District to confirm which city, which school attendance zone, and which set of taxing entities the parcel actually sits inside. Two homes on the same block of 78746 can answer that question differently, and the answer moves the number on the contract by six figures.

The commodity data on the portals will tell you 78746 is expensive. It will not tell you that "Westlake" is a brand covering four jurisdictions, that the Eanes ISD boundary ignores every one of them, and that the widely quoted median is a blend of homes that are not, on close reading, comparable properties. That is the argument of this brief.

One name, four jurisdictions

The area buyers call Westlake is anchored by the City of West Lake Hills, an incorporated municipality of roughly 3,700 residents with its own mayor, council, police, and zoning code. Beside it sits the City of Rollingwood, a separate incorporated city of about 1,500 residents covering 1.1 square miles. Around and between them, parcels fall inside Austin city limits or unincorporated Travis County. Each carries its own combined property-tax rate, which currently runs between 1.7% and 2.1% of assessed value depending on the mix of city, county, and district levies. On a $3 million home, that spread alone works out to roughly $51,000 to $63,000 in annual property tax before any homestead exemption is applied.

At the estate tier, the annual delta between the highest and lowest combined rates in 78746 can exceed $20,000 to $30,000 on a single property. The homestead exemption, filed with TCAD on a primary residence, then caps annual assessed-value increases at 10%, which becomes materially valuable in a submarket where entry pricing has climbed steadily since 2020. None of this is visible in a portal search. All of it is negotiable evidence during a valuation.

Why the medians disagree with themselves

The number you have already seen depends entirely on which source you opened first. As of Q2 2026, the reported medians for the same 78746 footprint sit as follows:

These are not typos. They are the same footprint measured through different filters: incorporated-city boundary versus ZIP versus attendance-zone versus algorithmic index. Transaction counts in West Lake Hills proper run around 34 closings over twelve months, and Westlake Hills tallied 54 to 85 days on market at a $756 per square foot median in early 2026, so a single lakefront trade can bend the reported median by hundreds of thousands of dollars in either direction.

The takeaway is not that any one source is wrong. It is that a "median" in a low-volume, high-variance submarket carries roughly the same signal-to-noise ratio as the last three cars sold at a specialty auction. Anchor to it at your peril.

The three premiums the median hides

The school-boundary premium

The Eanes Independent School District line runs along MoPac, not along any city boundary. Cross one street east and comparable homes step down by an estimated $200,000 to $400,000, according to trailing 24-month analyses of paired sales inside and outside the district edge. That is why some parcels near the Rollingwood and Barton Creek edges of 78746 read as "Westlake" in the listing address but assess and school differently in the county record. Verifying the attendance zone at TCAD before an offer, not after option period, is the single highest-return five minutes in a Westlake transaction.

The view-lot premium

Westlake Hills is hilly. Rollingwood is not. Trailing 24-month analysis of the Keenan Luxury Market Index places Rollingwood at roughly $897 per square foot and Westlake Hills at $655 per square foot, and the counterintuitive gap resolves once you separate lot topography from finish quality. View lots in Westlake Hills, concentrated in sections like The Oaks and Seven Oaks, carry a 15% to 25% premium over comparable non-view lots inside the same city. A flatter Rollingwood teardown that delivers new construction on a walkable street can transact above a Westlake Hills home with twice the square footage and a difficult driveway. Per-foot pricing is a summary statistic, not a valuation.

The new-construction premium

New inventory inside the Eanes attendance zone is genuinely scarce because the land is essentially built out. That scarcity is being tested in one visible way this year. The Overlook at Westlake, a MileStone Community Builders project of 48 luxury homes priced from $2.85 million to $5 million, is scheduled for move-ins in late 2026. It is one of the few opportunities in the current cycle to acquire a new home inside Eanes without a teardown-and-build timeline. The price band was set with the school-district premium baked in from day one, which is worth pricing into any comparable resale you tour beside it. Meanwhile, the teardown wave in Rollingwood is quietly compressing the historical entry-level discount that submarket used to offer.

What this changes about how you tour

A resident of the 78746 luxury market is not shopping by ZIP. The showings that lead to a signed contract tend to follow a stricter checklist:

1. Pull the TCAD parcel record before the tour and confirm the exact combined tax rate and attendance zone for that specific address.
2. Ask which side of the school boundary comparable recent sales sat on, and whether the seller's price references a public median or a boundary-adjusted comp set.
3. Separate the lot from the house. A view, a flat build pad, and mature canopy price independently of finish level.
4. Confirm whether inventory being shown is on the MLS at all. At $3M and above, the private-network share of Westlake Hills and Rollingwood transactions is meaningful, and portal-only searches understate the real competitive set.

The families who are happiest long-term are the ones who choose on daily lifestyle, not price per square foot.

That advice, offered by an agent with a quarter century inside 78746, tracks the data. The median is a starting point for conversation. It is not the answer to any question a buyer or seller actually needs answered.

What sellers should read from the same data

If your reference point is what your neighbor received in 2022, that market is behind us. Well-prepared, correctly priced homes in Westlake Hills continue to trade in the low-to-mid 20s in days on market, and the luxury tier above $1.5 million has appreciated meaningfully over the last twelve months. Overpriced homes sit past 90 days and then reduce, and the reduction typically nets less than a disciplined initial list would have. Presentation, staging, and photography carry more weight at $3 million than at any other price point on the map, because the buyer at that level is comparing an ensemble of lifestyle assets rather than a spreadsheet of square footage.

Private-network positioning matters here too. Sellers who prefer discretion frequently test the market through agent networks before any public listing, and the right buyer often surfaces before a sign goes in the yard.

Questions we hear before the first showing

Does every home with a Westlake address pay the West Lake Hills city tax? No. Some parcels inside 78746 sit in Austin city limits or in unincorporated Travis County, each with a different combined rate. Confirm the taxing entities at TCAD for any specific property before pricing in the "Westlake tax profile."

Is Eanes ISD guaranteed by ZIP code? No. The Eanes attendance zone covers most of 78746 and significant portions of 78733, but the boundary can split streets. School district assignment is verified parcel by parcel, not by mailing address.

Is Rollingwood still the value entry into the same school district? Historically yes, and structurally the entry point remains lower than Westlake Hills. In the last year the gap has narrowed as older Rollingwood homes are torn down and rebuilt at new-construction pricing on flat, walkable lots. Well-positioned Rollingwood properties currently trade in the $1.5 million to $3.5 million range.

Where is the retail and dining actually? Day-to-day errands run to the 360 Uno strip near Loop 360 and to Barton Creek Square. The Hill Country Galleria in Bee Cave, about ten minutes west on RM 2244, handles broader lifestyle retail. Most residents drive fifteen minutes east to the South Lamar and South Congress corridors, home to Uchi, Perla's, and Odd Duck, for a night out.

A closing thought

A Westlake valuation is a composition problem. Jurisdiction, attendance zone, topography, canopy, and finish each carry their own line item, and the median obscures every one of them. Reading the address correctly is the first move.
