Palm Beach County Spec Mansion Sells for $17M

What Sold at Stone Creek Ranch for $17 Million?

The sale involved Sundara, an 18,206-square-foot lakefront mansion on 2.67 acres at 9200 Rockybrook Way in Stone Creek Ranch, a gated community in unincorporated Palm Beach County west of Delray Beach.

Sundara sold for $17 million in January 2020 after being marketed for nearly $19 million. Michelle and Seth Cohen were the sellers, and an undisclosed Delaware LLC purchased the property.

The January closing drew attention because of the mansion’s size and price in a non-oceanfront location. The transaction ranked among the area’s highest-priced non-oceanfront sales at the time and set a local luxury benchmark for western Palm Beach County. Like other exclusive gated enclaves, Stone Creek Ranch offers residents 24/7 gated security.

Its scale also placed the property among Stone Creek Ranch’s largest sales. The deal later became an important reference point for the community’s rising property values, as the same address resold at higher prices. In 2025, a Stone Creek Ranch mansion, Palazzo di Lago, sold for $37 million, a 118% increase from its $17 million sale in 2020.

The sale helped establish the gated enclave as a major luxury market in Palm Beach County.

What’s Inside the 11,506-Square-Foot Mansion?

Set on 2.5 waterfront acres beside a manmade lake in Stone Creek Ranch, the mansion spans 11,506 square feet, with seven bedrooms and 11 bathrooms.

The interior layout begins with a grand entrance, a double living room, a formal dining room, and several lounge-style gathering areas. A club room has a 150-inch projection screen, while a separate theater adds another entertainment space.

The grayscale family kitchen is complemented by a chef’s kitchen with a private staff entrance. A bar features display cabinetry for premium spirits, and separate support areas help manage large-scale dining and entertaining.

The primary suite occupies an entire wing. Select bedrooms have fireplaces, while suites include walk-through dressing rooms and marble-clad bathrooms with sculptural soaking tubs.

Wellness amenities include a fitness center, a spa with a steam room, sauna, and Himalayan salt room, and an indoor pool. Outside, a pool and cabana-style features extend the leisure spaces. The sale comes amid rising inventory across Palm Beach County, where listings increased 22% year over year as of May 2025.

Why Do Buyers Choose Stone Creek Ranch?

Stone Creek Ranch attracts buyers seeking privacy, security, and estate-scale living without the density of an urban neighborhood. Its 2.5-acre estate parcels create broad buffers between homes, while private lakes and waterfront placement limit views from neighboring properties and exposure to boat traffic.

Armed security patrols reinforce the enclave’s controlled setting. The low-density plan accommodates expansive residences and compound-like layouts rather than compact subdivision living.

Waterways, preserved areas, and manicured grounds shape the scenery, while a gatehouse and stone bridge establish a managed arrival. A 1.5-mile promenade provides space for walking, running, and biking within the community, without requiring a golf-club membership.

Located in Delray Beach near Boca Raton, the enclave offers access to private schools, luxury retail, dining, and coastal amenities. Its appeal rests on combining regional connectivity with seclusion, land, and security.

What Does the Sale Say About Palm Beach County Luxury Homes?

The $17 million sale underscores the strength of Palm Beach County’s luxury market, where record-setting activity is persisting despite a shrinking supply of homes.

Through August 2026, the county logged 170 sales above $10 million, surpassing its full-year record of 169 set in 2025.

Meanwhile, active inventory fell 20.1% year over year in August, leaving buyers competing for limited high-end properties.

• West Palm Beach luxury sales rose 43.9% year over year in the three months ending July, the fastest increase among major metros analyzed.
• Palm Beach County’s million-dollar sales were 74% all-cash year to date in early 2026.
• The luxury median reached about $4.52 million, up 7.5% year over year.
• High-end single-family sales climbed 24.2% in Q2, while average prices rose 4.6% to $2.89 million.

These pricing trends indicate sustained demand, though strength remains concentrated in elite segments.

Assessment

The Stone Creek Ranch sale places an 11,506-square-foot estate among the county’s latest high-end transactions. Its price reflects continued demand for large, private properties in gated communities, though a single sale cannot establish a broader market trend.

The buyer, Russell Savage, acquired a home with extensive space and amenities. The transaction adds another data point for buyers and sellers tracking Palm Beach County’s luxury market.
