Boulder Mountain Estates Homes For Sale In Scottsdale
Boulder Mountain Estates is one of the smallest gated neighborhoods in North Scottsdale. It sits off Happy Valley Road at 118th Street in the 85255 ZIP code, just east of Troon Mountain and near the Troon Village area. The whole community is roughly 17 homes along East Buckskin Trail and East Desert Holly Drive, so you won’t see many listings here in any given year.
What makes it different from its neighbors? The architecture. K. Hovnanian Homes built the neighborhood in the mid-2010s as part of its “Line K” collection, with homes designed by Dutch designer Piet Boon. So instead of the Santa Fe and Tuscan styles you’ll find across much of Troon, Boulder Mountain Estates is all modern: strong lines, symmetry, lots of glass, and big mountain views from acre-plus lots.

How much do homes in Boulder Mountain Estates typically cost?
Home prices in Boulder Mountain Estates vary considerably depending on size, lot, views, renovations and amenities. As of September 2026, recent sales and the current listing range from approximately $2.4 million to $4.4 million, although a larger home on one of the biggest lots can exceed $4 million. With so few homes, each new sale can shift that range.
Does Boulder Mountain Estates have an HOA?
Yes. Boulder Mountain Estates has a homeowners association, and listing records show it covers common grounds maintenance and private street maintenance, along with upkeep tied to the gated entry. Ask for the CC&Rs and design guidelines early, and confirm whether any master association also applies to your specific lot.
Is Boulder Mountain Estates gated?
Yes, the entire community is gated. Every home in Boulder Mountain Estates sits behind the gate on its private streets, which is part of why the neighborhood stays so quiet.
What amenities does Boulder Mountain Estates offer?
There's no clubhouse, community pool or golf course inside the gate. Instead, residents get privacy, acre-plus lots and mountain views, with trails in the McDowell Sonoran Preserve, Troon North Golf Club, Troon Country Club and Pinnacle Peak Park all close by.
What schools serve Boulder Mountain Estates?
Boulder Mountain Estates is in Cave Creek Unified School District. Listings show Desert Sun Academy for elementary, Sonoran Trails Middle School and Cactus Shadows High School. Always confirm current boundaries with the district.
How far is Boulder Mountain Estates from Old Town Scottsdale and Phoenix Sky Harbor Airport?
Old Town Scottsdale is roughly 22 to 25 miles away, or about 35 to 40 minutes by car under normal traffic. Phoenix Sky Harbor Airport is approximately 30 to 35 miles away, usually about 40 to 50 minutes, mostly via Loop 101.
What should buyers know before buying a home in Boulder Mountain Estates?
Start with the lot. Sites here run from about 1 acre to roughly 3.4 acres on sloping ground, so two homes with the same Line K floor plan can differ a lot in privacy, usable yard and view direction, and that often explains price gaps of $1 million or more. Next, check whether the home has a casita or guesthouse, what's been updated since the original 2014 to 2016 build (pool, outdoor kitchen, finishes), and whether solar panels are owned or leased. Also, since the modern design is the whole point here, look closely at any remodel that changed the original look, and review the HOA's design rules before planning your own changes. Finally, a few homes have been offered for rent, so read the CC&Rs for lease terms if that matters to you.
How can I find homes for sale in Boulder Mountain Estates?
Use the View Listings search on this page to see anything currently for sale in Boulder Mountain Estates. Because listings are so rare, it's worth contacting The Holm Group so we can let you know as soon as something comes up, including off-market opportunities.
Who built the homes in Boulder Mountain Estates?
K. Hovnanian Homes built the neighborhood as its "Line K" collection, with homes designed by Dutch designer Piet Boon. It followed K. Hovnanian's first Arizona Line K neighborhood, Pinnacle Peak Place in Phoenix, and the community sold out in the mid-2010s.
Is Boulder Mountain Estates part of Troon?
Not exactly. Boulder Mountain Estates is its own small gated subdivision, though many search sites group it with the Troon Village area because it sits just east of Troon Mountain. Owning a home here doesn't come with a membership at Troon Country Club or any other club, which is joined separately.
Homes and Architecture
Every home here is a single-family Line K design, built from about 2014 to 2016. Buyers chose from a small set of modern floor plans, each with its own interior finish scheme, so the homes share a design language without looking identical. Original features seen in listings include white cabinetry, limestone countertops, Bosch appliances, multi-slide doors, gas fireplaces and three-car side-load garages.
Here’s what buyers typically see:
- Four to five bedrooms and roughly 3,500 to 4,900 square feet of living space
- Lots from about 1 acre to roughly 3.4 acres, many with sloping terrain that opens up mountain views
- Some homes with a guest casita or detached guesthouse with its own entrance
- Backyards that owners have built out over the years with pools, spas and outdoor kitchens
Pricing, as of September 2026: recent sales have ranged from about $2.45 million to $3.47 million, and the one current listing is asking $4.4 million on a 3.38-acre lot. Because there are so few homes, a single sale can move the numbers a lot, so treat any range here as a starting point, not a rule.
Market Overview
With only about 17 homes, resales in Boulder Mountain Estates are rare. Public records show roughly one sale a year since 2023, including $2.8 million in April 2024, $3.465 million in August 2024 and $2,447,500 in November 2025. Meanwhile, the newest listing on Desert Holly Drive went under contract within days of hitting the market in late September 2026.
Values have climbed well above where these homes started. For example, the Desert Holly home now listed at $4.4 million last sold in 2021 for about $3.05 million. That said, size and lot drive big gaps here. A 3,500 square foot plan on a one-acre lot and a 4,400 square foot plan with a casita on a larger lot can land more than $1 million apart. So if you’re serious about this neighborhood, it helps to be ready before a home comes up, and to have an agent watching for off-market chances.
Amenities and Lifestyle
Boulder Mountain Estates doesn’t have a clubhouse or shared pool. Instead, the draw is privacy, the gate and the desert all around you. Most of the lifestyle comes from what’s nearby.
Close to home:
- Tom’s Thumb Trailhead in the McDowell Sonoran Preserve, a short drive east off Happy Valley Road, with access to Tom’s Thumb, the Marcus Landslide trail and miles of preserve trails
- Troon North Golf Club (public, with the Monument and Pinnacle courses) and the private Troon Country Club a few minutes west
- Pinnacle Peak Park for its well-known summit trail and sunset views
- Everyday shopping, dining and groceries along Pima Road and around Pinnacle Peak Road
Plus, the setting is quiet. You’re at the edge of Scottsdale’s high desert, where dark skies, boulder outcrops and wildlife are part of daily life.
