A waterfront estate at 11465 Old Harbour Road has closed for $97.5 million, establishing the benchmark for Palm Beach County's most expensive residential transaction of 2025. The December closing caps a year of robust activity at the market's highest tier.
The property, located in unincorporated Palm Beach County rather than on the island itself, demonstrates that trophy-level pricing has expanded beyond Palm Beach's traditional boundaries. Buyers seeking the combination of waterfront position, privacy, and scale increasingly consider locations throughout the county when island inventory cannot satisfy their requirements.
The $97.5 million figure represents more than a single transaction, it reflects the sustained demand that has characterized Palm Beach's ultra-luxury segment throughout the year. While broader markets have shown signs of normalization, the county's highest tier has maintained pricing power that defies conventional real estate cycles.
Market data supports this resilience. Palm Beach County home sales rose 41 percent year-over-year in early 2025, with the $10 million-plus segment showing particular strength. Thirteen homes above $10 million sold in January 2025 alone, compared to just three in January 2024, a 333 percent increase that signals confidence among the most capitalized buyers.
For sellers of significant properties, the Old Harbour Road transaction provides validation. Properties positioned correctly, with the combination of waterfront, privacy, and quality that discerning buyers demand, can achieve pricing that reflects true scarcity value. The market rewards strategic positioning while still punishing aspirational overreach.
The record also suggests that Palm Beach County's geographic definition of "trophy" has expanded. Buyers focused purely on the Palm Beach island address may miss opportunities that the broader county presents.
