The Median Price in Westlake and Rollingwood Is Measuring the Wrong Thing

What does a median price actually price?

In most of Austin the answer is boring: houses. Comparable square footage, comparable lots, comparable finish levels, averaged into one number a buyer can use to plan a budget. In Westlake Hills and Rollingwood, sharing the 78746 ZIP code and the Eanes Independent School District boundary, that assumption breaks down in a way that matters before you ever write an offer. An appraiser assigned to a resale on a quiet Rollingwood street will often find almost nothing to compare it to. Recent closings nearby might be a 1960s original-condition home sold for the dirt underneath it, or a finished custom estate that cost more to build than the house it replaced was ever worth. Neither one tells the appraiser what a livable, unrenovated three-bedroom on the same block is actually worth, because the market isn't really pricing houses on that street anymore. It's pricing land, with a house attached almost as an afterthought.

That single fact reshapes how a buyer or seller should read every other number attached to this corridor.

What an Appraisal Actually Measures in a Teardown Market

Rollingwood's active inventory is thin enough that it commonly sits at fewer than five listings at any given moment across the entire city. Typical lots run roughly a fifth of an acre to three-quarters of an acre, small by Hill Country standards but scarce enough, paired with the shared Eanes ISD boundary, that demand rarely lets up. When inventory is that constrained, a single transaction can carry disproportionate weight in whatever "median price" a portal displays that month.

Here's the mechanic that catches buyers off guard. A teardown purchased purely for the lot, and a fully renovated estate sold for its finish level, can each pull Rollingwood's published median by a few hundred thousand dollars in either direction depending on which one closed most recently. That's not a data error. It's what happens when a market's real product is buildable land and the house on top of it is closer to a variable than a fixed input. For a lender's appraiser trying to support a purchase price with recent comps, that means the comp pool for an ordinary resale is often thinner and stranger than it looks on paper. Buyers financing a purchase in Rollingwood should expect this conversation with their lender early, not after an appraisal comes back low relative to the contract price.

The Number on the Portal Versus the Number in the Room

Ask two different sources for the same metric in this corridor and you'll often get answers that don't just differ, they contradict each other on direction.

One analysis has Rollingwood commanding a higher price per square foot than Westlake Hills. Another has it the other way around. Both can be technically accurate and still describe different slices of a market this small, because a handful of closings in either city can swing the average enough to flip the ranking. The lesson isn't which number is right. It's that neither number is a substitute for pulling closed comps on the specific street you're evaluating, filtered by lot condition, not just square footage and bedroom count.

There's a second layer hiding under both of these figures. Sellers at the $3 million-plus level in this corridor frequently don't need to sell on a timeline, and when an offer doesn't meet their number, the common move is to pull the listing and shop it privately rather than sit on the MLS accumulating days on market. That means the visible inventory count and the visible time-on-market figure both understate the real competitive set a serious buyer is up against. A published months-of-supply figure sitting in the high single digits can look like buyer leverage on the surface while a meaningful share of comparable homes are transacting somewhere a portal search will never surface them.

Same Zip Code, Same School Boundary, Different Machine

Beyond the shared ZIP code and the shared Eanes ISD boundary, which buyers should always confirm against the district's own attendance boundary map rather than a listing description, the two cities function differently as construction environments. Rollingwood's lots tend to be flatter and more uniform, which makes site work more predictable and can shave real money off a custom build compared to Westlake Hills, where steeper hillside lots add engineering and foundation costs before the first stud goes up. Rollingwood also runs its own municipal government, including its own police department and its own zoning authority, separate from the City of Austin, which gives it more direct control over things like traffic patterns and development standards than an unincorporated area would have.

That governance structure isn't a background detail this year. It's actively shaping the one infrastructure question every buyer on a MoPac-adjacent street in either city should be tracking before they close.

The Highway Vote That Just Happened

The Central Texas Regional Mobility Authority has spent several years developing the MoPac South Expansion Project, an 8-mile stretch of toll and express lane work between Cesar Chavez Street and Slaughter Lane. Rollingwood officials, including Mayor Gavin Massingill and council member Sara Hutson, pushed back publicly on earlier design iterations, arguing the project prioritized north-south commuters at the expense of the east-west access residents actually use to reach Bee Cave Road and Loop 360. The Mobility Authority published a draft environmental assessment on February 13, 2026, and opened a formal public comment period that ran from March 9 through May 3, 2026.

This spring, on April 22, 2026, the West Lake Hills and Rollingwood city councils jointly agreed to send a letter of conditional support for the project, a shift from years of pushback. Their support is contingent on three specific commitments from the Mobility Authority: full funding for a diverging diamond intersection at MoPac and Bee Cave Road, noise barriers extended to the Rollingwood side of the highway to match what's already planned for the Zilker side, and no change to the previously agreed lane elevation.

According to West Lake Hills Mayor James Vaughan, the diverging diamond intersection is projected to cut peak-hour delays by 48 to 58 percent overall, with westbound delays reduced by as much as 83 percent.

For anyone evaluating a MoPac-adjacent address in either city, this is worth watching rather than assuming settled. As of this spring, the intersection funding was still listed as pending coordination with local municipalities, and the project still has to clear final environmental review before construction timelines firm up. A commute that's currently the single most common complaint from residents in this corridor could meaningfully improve, but the disruption of construction along MoPac-adjacent streets will come before the benefit does.

The One New Build in a Market That Doesn't Build

New construction almost never happens in Eanes ISD because there's so little undeveloped land left, which is what makes The Overlook at Westlake worth understanding even if it's technically addressed in Lost Creek rather than Rollingwood or central Westlake Hills. MileStone Community Builders is developing 48 homesites on the former Marshall Ranch parcel off Lost Creek Boulevard, with homes ranging from 3,300 to 5,000 square feet. The builder began work on a model home at 1300 Lost Creek Boulevard in late 2025, when eight of the 48 homesites had already sold, with move-ins expected to begin in late 2026.

The property carries an unusual piece of local history. The development's 37 acres include the burial site of Robert and Eliza Eanes, whose family gave the school district its name, and whose original log cabin and one-room schoolhouse stood on this land starting in 1872. The Eanes Cemetery is designated a historic site by the state of Texas, and the builder has installed temporary fencing to protect it during construction. It's a small detail, but it's a useful reminder of how long this land has been valuable for reasons that have nothing to do with the current price per square foot.

For buyers who specifically want new construction in this school boundary rather than a renovation project, this is close to the only option on the table right now, and that scarcity is itself part of the pricing story in the rest of the corridor.

What This Means If You're Comparing These Two Right Now

1. Pull closed comps filtered by lot condition, not just square footage, before trusting any published median for a Rollingwood address.
2. Ask your lender directly how they plan to handle a thin comp pool before you're under contract, not after an appraisal comes in low.
3. Verify Eanes ISD boundary status for any specific address using the district's own map rather than a listing description or ZIP code.
4. If you're evaluating a property near MoPac, ask specifically about the diverging diamond funding status and construction timeline before assuming the commute improvement is locked in.
5. Recognize that a low published days-on-market or inventory figure in this corridor may still be hiding a meaningful slice of activity that never touched the MLS.

None of these five things show up on a portal listing page. They're the difference between reading this market from the outside and actually transacting in it.
