David MacNeil, the billionaire founder and CEO of WeatherTech, has sold his waterfront estate in Fort Lauderdale, Florida for $34 million in less than 21 days. The 11,700-square-foot, six-bedroom home was part of MacNeil's broader real estate repositioning as he quietly assembles a rare ocean-to-Intracoastal property in the exclusive town of Manalapan, located 10 miles south of Palm Beach.

Why it matters

MacNeil's real estate moves highlight the growing appeal of South Florida's coastal communities among the ultra-wealthy, who are drawn to the region's tax advantages, luxury amenities, and exclusive enclaves. The sale also showcases the speed at which high-end properties can transact in the current market.

The details

MacNeil's just-sold Fort Lauderdale home sits on a point lot inside the guard-gated Harbor Beach community, featuring 300 feet of Intracoastal frontage, soaring ceilings, marble and wood floors, four fireplaces, six wet bars, a commercial-grade elevator, and a third-floor lounge with sweeping water views. The property also includes a 90-foot infinity-edge lap pool, sun terraces, and a private dock with direct ocean access.

  • MacNeil sold the Fort Lauderdale estate in less than 21 days.
  • In April 2024, MacNeil purchased a 2-acre lot in Manalapan for $38.5 million.
  • In May 2025, MacNeil added an adjacent 1.5-acre parcel in Manalapan for $55.5 million.
