What clients say
“Johnny not only helped me buy a great home in Lakeway at a great price back in January of 2021 but he then helped me sell that same house for over $200K of what we purchased it for only 9 months later. Johnny helped us get an offer that was $50K over our asking price. We are extremely happy with Johnny as our "go-to" guy for anything related to real estate.”
Ryan B. · Lakeway buyer & seller
“Johnny guided us to our dream home. He understood exactly what we were looking for and he made the process flow smoothly and gracefully. I never imagined buying a house could feel so easeful! We are so grateful we had Johnny to show us just how smooth the process can be!”
Brandilyn B. · Lake Travis buyer
“I am so grateful that my family and I found Johnny! Johnny is incredibly hardworking, knowledgeable, and detail-oriented, and he TRULY cares about his clients. He worked nonstop to help us find our perfect home and we couldn’t be happier with the results of his hustle and care.”

Key Takeaways
- Rob Roy on the Lake is a collection of private estates on Lake Austin's Westlake Hills shore — arguably Austin's single most coveted waterfront address.
- MLS-recorded sales closed between $1.85M and $5.65M from January 2025 through October 2, 2026, with a 2026 median of $2.81M; direct Lake Austin waterfront estates are a separate, higher-priced market and often trade privately.
- Lake Austin is a constant-level lake (Tom Miller Dam) — no drought-year water drops, no stranded docks. What you buy is what you have, every year.
- Residents are in Eanes ISD / Westlake High School — the gold standard public school district in Central Texas.
- Most transactions happen off-market. If you're waiting for Zillow, you've already missed the inventory. Johnny Ronca has sold Lake Austin waterfront in this corridor for 20 years, including to celebrity clients.

What Do Homes in Rob Roy Sell For? 2025 vs 2026 Closed Sales
Short answer: Rob Roy single-family homes closed at a median of $2,812,500 ($549.43 per square foot) across 12 MLS sales from January 1 to October 2, 2026, compared with $2,444,061 ($523.71 per square foot) across 10 sales in all of 2025. Median days on market went from 67.5 to 18.5, and sellers closed at 93.0% of original list price versus 88.7%. The median home that sold in 2026 was 21% larger (4,314 to 5,202 sq ft), so price per square foot is the fairer comparison than the headline median. Like for like, large luxury resales (3,600–5,400 sq ft, built 1981–2011, no new construction) closed at a median $2,482,000 in 2026 against $2,405,175 in 2025, or $554.56 against $517.49 per square foot.
| Rob Roy (78746) | Sales | Median close | Median $/sq ft | Median days on market | Close ÷ original list |
|---|---|---|---|---|---|
| All single-family · 2025 (full year) | 10 | $2,444,061 | $523.71 | 67.5 | 88.7% |
| All single-family · 2026 (Jan 1–Oct 2) | 12 | $2,812,500 | $549.43 | 18.5 | 93.0% |
| Same months of 2025 (Jan 1–Oct 2) | 6 | $2,725,886 | $523.71 | 67.5 | 90.7% |
| Last 90 days (Jul 4–Oct 2, 2026) | 5 | $2,775,000 | $554.56 | 12 | 94.1% |
Same Size, Same Age: Rob Roy Homes in 2025 vs 2026
Every row compares the same kind of home, year against year: single-family resales with 3+ bedrooms, 2+ full baths and a 2+ car garage, built 1981–2011, with new construction left out. Each size band runs 20% either side of 2,000, 3,000, 4,500 and 6,750 square feet, the way an appraiser brackets a subject home.
| Home size | 2025 sales | 2025 median close | 2025 $/sq ft | 2026 sales (Jan 1–Oct 2) | 2026 median close | 2026 $/sq ft |
|---|---|---|---|---|---|---|
| Mid · 2,400–3,600 sq ft | 1 | — | — | 1 | — | — |
| Large luxury · 3,600–5,400 sq ft | 6 | $2,405,175 | $517.49 | 5 | $2,482,000 | $554.56 |
| ↳ Large luxury with a private pool | 5 | $2,375,000 | $465.16 | 5 | $2,482,000 | $554.56 |
| Estate · 5,400–8,100 sq ft | 1 | — | — | 5 | $3,500,000 | $535.62 |
Every Estate sale in the table had a private pool. A dash means fewer than five sales in that band that year, so no median is published. Also left out: 1 resale built outside 1981–2011 and 2 outside 1,600–8,100 sq ft.
Rob Roy is selling faster and closer to asking in 2026: a median 18.5 days on market against 67.5 in 2025, and 93.0% of original list price against 88.7%. The last 90 days were tighter again, with five closings at a median of 12 days. Every MLS sale since January 2025 closed between $1.85 million and $5.65 million, with medians of $2.44 million in 2025 and $2.81 million in 2026. Direct Lake Austin waterfront is a separate market with its own numbers: see the Lake Austin waterfront sales table.

The Rob Roy Community Guide
Why Rob Roy Stands Alone: Three Pillars
Rob Roy on the Lake commands its premium for three intersecting reasons: the geography of the lake itself, the prestige of the Westlake Hills municipal address, and the simple scarcity of what's here. Let me explain all three.
Pillar One: The Lake Difference (And Why It Changes Everything)
This is the most important conversation I have with every serious Lake Austin waterfront buyer, and it genuinely changes decisions.
Lake Travis is a Highland Lakes reservoir — beautiful, expansive, fed by the Pedernales and Colorado Rivers. During extended drought, Lake Travis drops. Significantly. In recent cycles, the lake has fallen 30–60 feet below full pool, exposing boat ramps, stranding marina docks, and temporarily rendering waterfront properties non-functional for boating.
Lake Austin is controlled by Tom Miller Dam and maintained at a constant level year-round. It does not significantly fluctuate with drought. It does not drop and strand your dock. What you buy is what you have, every day, every year, for the life of your ownership.
For a buyer spending $10M+ on waterfront property with a 20–30 year horizon, the certainty of Lake Austin's constant level is not a minor feature. It's a foundational distinction between owning waterfront and owning guaranteed waterfront.
Additional Lake Austin advantages:
- Narrower, calmer water — wake zones are regulated, boat traffic is lower, the lake character is more intimate and peaceful
- Cleaner water — reduced boat traffic and protected cove sections mean notably higher water quality
- Closer to downtown — Rob Roy to downtown Austin is 10–15 minutes. Lake Travis waterfront is 30–45 minutes minimum
Pillar Two: Westlake Hills and Eanes ISD
Rob Roy is physically within Westlake Hills — one of Austin's most exclusive incorporated municipalities — which matters for three reasons:
Eanes ISD access: Rob Roy residents are zoned to Eanes Independent School District and Westlake High School — consistently ranked among Texas's top 5 public high schools for academic performance and college placement. For families with school-age children, Eanes ISD is the gold standard in Central Texas. This is a meaningful differentiator over Lake Travis waterfront (Lake Travis ISD), which is excellent but doesn't carry the same generational prestige.
Westlake Hills zoning protections: The city maintains its own development standards independently of Austin. This provides stronger protection against incompatible development and preserves the neighborhood character over time.
The address itself: In Austin's luxury market, "Westlake Hills" signals something specific to people who know the market. It's not just geography — it's a reference category.
Pillar Three: Irreplaceable Scarcity
There are a finite number of Lake Austin waterfront lots in the world, and the ones in Westlake Hills are the most coveted. They don't make more. When a property comes available here, it doesn't compete with a new subdivision around the corner.
This scarcity creates a dynamic unlike almost any other residential market in Texas: most transactions happen privately, prices are negotiated between parties with long time horizons, and the agent relationship is the mechanism that makes deals happen — not the MLS.
The Privacy Factor: Estates, Not a Community
Rob Roy is not a HOA community with shared amenities and an architectural review committee. It's a collection of private estates that happen to share an extraordinarily exclusive geographic address. There's no clubhouse. No resort pool. No managed gate in the traditional sense.
What you have is your property, your dock, your frontage on Lake Austin, and virtually no visible neighbors. For buyers who've graduated from resort-style communities and are ready for genuine estate privacy, Rob Roy offers something fundamentally different. The estate experience is complete and private.
This is not for everyone. If you want a programmed community with organized events and a social calendar built in, look at Spanish Oaks or Rough Hollow. If you want your own world on the water with 10–15 minutes to downtown Austin — Rob Roy.
The Buyer Pool: Two Austin Generations Meeting at the Water
Rob Roy properties have historically attracted two distinct buyer profiles.
Old Austin money — multi-generational Texas wealth, often in energy, real estate, or manufacturing. Some families have owned these properties for 20–40 years. They don't sell unless compelled by estate transitions, family circumstances, or an offer that clears a very high bar. When they do sell, discretion is the requirement.
New Austin tech wealth — founders, executives, and investors who've monetized equity from Austin's tech boom and are looking for the definitive Austin address. They've often looked at multiple Austin neighborhoods and done the research. When they find Rob Roy, they tend to understand quickly why it's different.
When a property surfaces in Rob Roy, it typically attracts both buyer pools simultaneously. Competition is quiet but real.
Lifestyle: What Life Actually Looks Like Here
Morning lake time. Lake Austin at 6:30am — before boat traffic — is genuinely serene. Cypress trees, still water, reflected light, absolute quiet. Several Rob Roy owners have told me this is their most treasured part of the lifestyle, and I believe them. Having paddled and fished this lake myself, I understand exactly what they mean.
Effortless boating. Direct dock access means a boat on a lift, not a marina slip. You're on the water in two minutes from your living room, any time you want. No waiting. No marina fees. Just your boat, your dock, your lake.
Understated entertaining. Rob Roy is not a community for showing off. The entertaining here is intimate, private, and among peers. The lake is the centerpiece — sunset cruises, dock dinners, weekend mornings on the water. It's one of the few Austin addresses where the lifestyle matches the price tag completely.
No commute penalty. Westlake Hills to downtown Austin is 10–15 minutes. My old neighborhood in Barton Hills is literally around the bend from the south shore of Lake Austin. Rob Roy owners can be at downtown restaurants, at meetings, or at Barton Springs Pool in minutes. The estate seclusion doesn't come at a commute cost. That combination — genuine waterfront estate privacy AND proximity to a world-class city — is extraordinarily rare.
Schools: Eanes ISD
Rob Roy residents are zoned to Eanes Independent School District — one of the most consistently top-ranked public school districts in Texas.
The Eanes ISD pipeline: Elementary → Hill Elementary or Bridge Point Elementary → West Ridge Middle → Westlake High School (consistently ranked top 5 in Texas; exceptional AP program, strong athletics and fine arts).
Eanes ISD is the school district advantage that most clearly differentiates Rob Roy and the broader Westlake Hills address from comparable Lake Travis waterfront product (Lake Travis ISD, also strong but without the same historic prestige). For families with children, this distinction alone is worth understanding before you choose your lake.
Rob Roy vs. West Rim vs. Lost Creek: Which Is Right for You?
Factor | Rob Roy | West Rim | Lost Creek |
|---|---|---|---|
Water access | Direct Lake Austin waterfront + dock | No waterfront (canyon views) | No waterfront |
School district | Eanes ISD | Eanes ISD | Eanes ISD |
Entry price | ~$5M | ~$2.5M | ~$1.2M |
Top end | $20M–$25M+ | ~$8M | ~$4M |
Privacy | Estate-level, no HOA | Residential, more neighbors | Established neighborhood |
Lifestyle | Lake living, private estate | Views, quiet, wooded | Family-friendly walkable |
Drive to downtown | 10–15 min | 12–18 min | 15–20 min |
Best for | True waterfront estate lifestyle | Views + Eanes ISD at lower price | Eanes ISD without premium cost |
The honest narrative: If you want Lake Austin waterfront in Westlake Hills with Eanes ISD schools and genuine estate privacy — Rob Roy is the answer, and nothing else in Austin is a true substitute. West Rim offers the Eanes ISD address and dramatic Hill Country/canyon views at a lower price point, but it's emphatically not waterfront. Lost Creek is the practical, family-friendly 78746 neighborhood without the waterfront premium or the dramatic siting — excellent value for Eanes ISD access.
The choice between Rob Roy and Lake Travis waterfront usually comes down to one question: is the constant-level lake, the Eanes ISD advantage, and the proximity to downtown worth the price premium over Lake Travis? For serious waterfront buyers with a long-term horizon, the answer is typically yes.
Why I Love Selling Rob Roy (And Why It's Different)
Twenty years of Austin luxury real estate, and there is genuinely nothing like Rob Roy on the Lake. Not in this city, and not in many cities.
I've sold Lake Austin waterfront in this corridor for two decades. I've had the honor of representing buyers and sellers at some of Austin's rarest addresses — including, yes, a few transactions where the buyer's privacy requirements were at a level that required a different kind of operating process entirely. Celebrity clients choose Lake Austin waterfront in Westlake Hills for exactly the reasons I've described: the lake level, the proximity to downtown, the schools, and the privacy. When you've done that work, you understand what's actually valuable here and what's just marketing.
What I tell every Rob Roy buyer candidate: this market will not wait for you. Properties here don't sit. They don't go through an extended price discovery process on Zillow. They surface through private networks, get matched to qualified buyers, and transact. If you're interested in Rob Roy on the Lake, the move is to tell me now — so that when something surfaces through my network, you're already in the conversation.
My network includes past Rob Roy sellers, current owners considering future sales, estate attorneys handling family property transitions, and top agents who share information on upcoming opportunities. When you tell me you're looking for Lake Austin waterfront, I make calls. Not searches.
The testimonials say it better than I can:
> "Johnny found our Rob Roy property before it was ever listed. He knew the owner wanted to sell quietly and made the introduction. We saw it on a Tuesday and signed a contract Thursday. Without his network, this house would never have been available to us."
> — William & Caroline T., Rob Roy buyers, 2025
> "We'd been looking at Lake Travis waterfront for two years and could never understand why certain properties felt different. When Johnny took us to Rob Roy and explained the constant-level lake difference, everything clicked. We moved our entire search."
> — Gregory & Sarah M., Rob Roy buyers, 2026

“Johnny did an incredible job helping me to negotiate the price down on this house. We got tens of thousands of dollars in discounts that I would not have had without his support. He remained available to me through several months of escrow while the house was being fixed up and was incredibly helpful in identifying new contractors.”

Frequently Asked Questions
Why is Lake Austin different from Lake Travis for waterfront?
Lake Austin is controlled by Tom Miller Dam and held at a constant level year-round. Lake Travis fluctuates significantly with drought — it has dropped 30–60 feet in recent drought cycles, stranding boat docks and eliminating water access for months or years. For a $10M+ property purchase with a 20–30 year horizon, the certainty of constant-level water is a foundational distinction. I've guided many buyers from Lake Travis searches to Lake Austin once they understood this — and none of them have regretted it.
How does the Rob Roy market actually work — why aren't properties on MLS?
Rob Roy owners are typically selling generational assets. They want vetting. They want privacy. They want to know who's buying before strangers walk through the home. The agent relationship is the mechanism that makes transactions happen — not the listing portal. In a typical year, perhaps 5–10 transactions occur in this enclave, and the majority happen through private agent-to-agent or direct-owner introductions.
What makes a Rob Roy property more valuable vs. less?
Linear frontage footage (more is dramatically better), dock and boat slip quality and configuration, home quality and renovation recency, view corridor from primary living spaces, lot depth and privacy buffer from neighbors, and presence of guest house or additional structure. At the upper end, you're often buying based on irreplaceability — the specific combination of frontage, position, and quality that makes a given property one-of-a-kind.
What's the school district situation for families?
Rob Roy is zoned to Eanes ISD and Westlake High School — consistently among Texas's top 5 public high schools. This is the gold standard for public education in Central Texas. It's a meaningful differentiator from Lake Travis waterfront (Lake Travis ISD, also strong but different tier of historic prestige).
Is Rob Roy appropriate for families with children, or is it more of a second-home market?
Both, but the community skews toward established primary residences for families who want the complete package: Eanes ISD schools, lake access, downtown proximity, and estate privacy. It's less of a weekend-house market than, say, some Lake Travis communities — the Westlake Hills location makes it genuinely functional as a daily driver.
How quickly do properties transact when they become available?
When a property surfaces in Rob Roy, qualified buyers typically see it within days and competitive situations develop quickly. The testimonial above — Tuesday showing, Thursday contract — is not unusual for pre-positioned buyers who already have financing confirmed and parameters aligned. Buyers who wait to "start the process" when something appears typically miss it.
