WeatherTech founder David MacNeil has reportedly unloaded his Harbor Beach waterfront estate at 84 Isla Bahia Drive in Fort Lauderdale for roughly $34 million, and he did it at warp speed. The three-story point-lot spread, a turnkey waterfront home with a long dock and a large infinity pool, appears to have gone under contract in under three weeks after hitting the market in mid-March.

The New York Post first reported the fast closing and noted that the buyer's name has not yet shown up in public records. Listing agent Chad Carroll told the outlet that "buyers move quickly on properties that check every box," and the report added that broker Brett Bass represented the buyer.

Harbor Beach point lot with serious water frontage

The roughly 11,700-square-foot, three-story home sits on a coveted point lot inside the guard-gated Harbor Beach neighborhood, with nearly 300 feet of combined Intracoastal frontage. The property features a private dock and what the listing describes as an approximately 90-foot infinity lap pool. Inside, the house is laid out with six bedrooms, multiple wet bars, four fireplaces and a commercial-grade elevator, according to Compass.

Listed in mid-March, off the market in days

MLS records show the house hit the market in mid-March with an asking price in the mid-$30 millions, going live on March 16. From there, it barely had time to make the rounds before a deal came together, with third-party listing pages logging only days on market before the reported trade, per ByTheSeaRealty.

One sale in a much bigger Florida play

The Fort Lauderdale deal is just one piece of MacNeil's recent South Florida real estate moves. Reporting and public records show he paid about $38.5 million for a Manalapan lot at 1120 S. Ocean Blvd. in April 2024 and later tacked on an adjacent parcel for roughly $55.5 million. Taken together, those buys have pushed his ocean-to-Intracoastal assemblage into the roughly $94 million range, according to Palm Beach Daily News.

Ultra-lux waterfront where speed still wins

Local brokers say South Florida's ultra-luxury waterfront market continues to reward buyers who can move quickly on turnkey homes with private docks and deep-water access. That dynamic has helped several high-end deals close on compressed timelines in recent months, with market watchers pointing to similarly tight windows between listing and sale in Miami Beach and Palm Beach, according to The Real Deal.

As of the time the transaction was reported, the buyer's identity had not appeared in public records, and online listings and county records may still be updating as officials process the deed transfer, according to the New York Post. For now, the sale stands as another example of how fast deep-pocketed buyers are willing to move in South Florida's top coastal enclaves.
