You have already seen the median price for 78746. You have probably seen three different medians, from three different sources, published in the same month. One puts a typical West Lake Hills home near $1.64M. Another says $2.04M. A third says $2.8M. A fourth quotes an average listing of more than $3.6M.
They are all technically correct. They are also all misleading, because in an incorporated city where two homes closed in a typical month and no two lots have the same buildable envelope, a median is a rumor. What you are actually buying in West Lake Hills is a lot, a set of city code constraints, and the school district that sits on top of them. The house is almost secondary.
One market, several medians
Here is what different sources reported for the West Lake Hills area in 2026, using the same MLS data feed and overlapping time windows:
| Source | Metric | Reported figure |
|---|---|---|
| Keenan Group (Aug 2026 snapshot) | Median home price, Westlake Hills | ~$1.64M |
| Orchard (2026 report) | Median sold, 71 DOM, 11.58 months supply | $1.895M |
| The Keenan Group, 78746 zip | Trailing 12-month median as of Jul 31, 2026 | $2.04M |
| Zillow ZHVI | Typical home value, West Lake Hills | $2.21M |
| Grewal RE Group | Median sale price, early 2026 | ~$2.2M |
| Spee Neuren Group (Jun 2026) | City median | ~$2.8M |
| Redfin (via Grimes Group) | March 2026 median on 2 sales | $2.73M |
| HAR.com | March 2026 average listing at $870/sqft | $3,665,390 |
The spread is not sloppy reporting. It is the market. As of March 2026, Redfin's West Lake Hills median rested on two closings for the month, which is why Grimes Group and others explicitly warn that monthly medians here are directional rather than definitive. When a market moves 15 to 30 homes at a time, a single lakefront estate or a single 1970s teardown can swing the "median" by seven figures.
Three tiers, three completely different transactions
Underneath the headline number are three distinct sub-markets, and the experience of buying at each level barely rhymes with the others.
$1.5M to $2.5M — the land tier. Expect an original 1960s to 1990s home on a standard lot. Many are functional teardown or heavy-renovation candidates. The house is a placeholder; you are buying dirt and an Eanes ISD attendance zone. Some of the strongest long-run bets in the city have been made here by families who live in the existing structure for a few years and then rebuild.
$2.5M to $5M — the sweet spot. This is where most family buyers land. Renovated homes, newer construction on good lots, and updated mid-century houses with modern additions. This tier is where the phrase "move-in ready in Eanes ISD" actually applies.
$5M and up — the estate tier. Hill Country views, Lake Austin frontage in the broader Westlake corridor, gated privacy. Comparable sales here are not really comparable. Each transaction is its own case study.
A buyer with a $3.5M budget in a neighboring Eanes ISD community is often still buying a teardown. The same budget inside the city limits of West Lake Hills has a real shot at a finished, renovated home. That is a meaningful mechanical difference between two markets that look identical from a portal search.
The buildable envelope is the actual price mechanism
Here is the part the portals will not tell you. Because West Lake Hills is an incorporated city with its own building department, what a specific lot can hold is often more important to its value than the square footage of whatever structure is on it today. Two lots on the same street can trade at very different prices because one of them can support the pool, the guest house, and the wider drive that a modern buyer expects, and the other one cannot.
The relevant constraints, all from West Lake Hills' own code:
- Impervious cover is capped at 25% for single-family lots of 0.5 acre or larger. Roof, driveway, patio, pool deck, and pavers all count. Smaller lots on central wastewater get a modest bonus. This is set out in the city's Building and Development FAQ and Code Sections 22.03.001 and 22.03.281.
- Driveways cannot exceed a 20% grade at any point after construction, and no part of the drive may rise more than 6 feet above natural grade below. Only one driveway per primary dwelling, maximum 20 feet wide. See ecode360, Division 5.
- Where average natural slope beneath the foundation is 25% or greater, no principal structure may rise more than 32 feet above natural grade. Nonresidential development is not permitted on slopes above 25% at all. That is in Division 8, Dimensional Regulations.
- Post-construction runoff cannot exceed pre-construction runoff. Drainage plans are reviewed by the City Engineer, and Type II and Type III projects trigger extensive erosion control obligations.
- Oak wilt certification is required within 14 business days of a complete application, and all submittals run through MGOConnect. A Preliminary Conference with city staff is mandatory before you can even file.
- Permeable pavers count as 100% impervious. That is deliberate. Buyers who assume they can "add a pool later" without touching their impervious budget frequently learn otherwise.
Translate that into offer terms. A steep lot with a 22% average slope and a tight impervious budget may not accommodate the third garage bay, the sport court, or the ADU the buyer is quietly planning. A gently rolling half acre with existing driveway alignment closer to street grade can. The premium the market assigns to the second lot is not arbitrary.
What inspections actually surface here
The other piece the median hides is what shows up under contract. West Lake Hills homes sit on expansive clay soils, on hillside lots, with mature live oaks whose roots pull moisture from foundation perimeters through Central Texas droughts and heavy rain cycles.
The specifics matter when you are pricing repairs against list. Lake Austin Pro Foundation Repair, which works throughout the 78746 area, publishes typical costs of $1,200 to $1,800 per steel push pier, with most West Lake Hills slab homes requiring 8 to 20 piers. That places typical foundation projects in the $10,000 to $30,000 range, and sloped hillside lots often push higher because of excavation, root-sensitive placement, and access limitations on terraced sites. Homes built before 1980 frequently still have cast iron drain lines, which is another line item that appears in inspection reports and vanishes from casual portal browsing.
Steep driveway access, drainage against the slab, and settlement around retaining walls are the friction points local agents see repeatedly in option period negotiations. Budget for them going in.
How to read leverage in a low-volume market
Orchard's 2026 data puts West Lake Hills at 11.58 months of supply and a 90.83% median sale-to-list ratio. In most Austin sub-markets those two numbers together would signal a firm buyer's market. Here they mean something more specific.
Low sale-to-list is real. Homes are moving well below asking, and 66.67% of listings had price drops in the last 30 days of Orchard's report. That is negotiating leverage. But the leverage is unevenly distributed. Correctly priced homes in the $2.5M to $5M sweet spot still transact in the low-to-mid twenties on days on market according to Grewal RE Group's early 2026 read. Overpriced land-tier homes languish. If you write the same offer strategy for both, you will overpay for one and lose the other.
The read is: use the buyer's-market posture to negotiate on lots with obvious buildable-envelope friction, and price closer to ask on the rare finished home whose envelope already matches how modern buyers use the house.
Questions worth asking before you write an offer
- What is the average natural slope beneath the existing foundation, and what is the current impervious cover percentage against the 25% cap?
- Does the driveway already exceed the 20% grade rule, or would any planned reconfiguration require a variance?
- What is the oak wilt status of the protected trees, and where are they in relation to the buildable footprint?
- If the home predates 1980, what does the sewer scope show for cast iron drain lines?
- What is the septic system's age, capacity, and last inspection date, and is central wastewater available at the street?
Answers to those five questions will tell you more about what a West Lake Hills property is worth to you than any median in the MLS.
FAQ
Why do published medians for West Lake Hills disagree so much? Different sources use different geographies (city limits vs. 78746 vs. broader Westlake corridor), different time windows (30-day vs. trailing 12-month), and different metrics (sold vs. list vs. Zillow ZHVI). Monthly closings are often in the low single digits, so one lakefront sale can move a "median" by a million dollars.
Is 11.58 months of supply really a buyer's market here? Directionally, yes. In practice, leverage concentrates on lots with buildable-envelope constraints, older systems, or aggressive pricing. Finished homes on clean lots in the sweet-spot tier still move quickly.
Can I add a pool or ADU to any West Lake Hills lot later? Not automatically. Impervious cover, setbacks, slope rules, tree preservation, and septic capacity all interact. Confirm feasibility before you close, not after.
