McMackins Find Buyer for $85 Million Manalapan Mansion

An $85 million lake-to-ocean estate in Manalapan with its own discreet tunnel to the beach is under contract to a buyer.

Cindy and Ron McMackin, who own the engineering subcontracting firm Pan-Pacific Mechanical, are selling the seven-bedroom, 11-and-a-half-bathroom mansion at 1660 South Ocean Boulevard, according to the Multiple Listing Service and property records. Cindy is the president of their company, which has offices in California and Hawaii, and Ronald is the chairman and CEO.

The 22,900-square-foot, 2-acre estate is on the market with Premier Estate Properties’ Margit Brandt. Robert Burrage’s RWB Construction Management built the home. Benedict Bullock Group designed the property, and Marc-Michaels handled the interiors, according to the listing. The Real Deal toured the tunnel in 2024. It leads to an air-conditioned beach bungalow:

The property has 165 feet of ocean frontage, a pool, spa, covered loggia, a wellness wing, eight-car garage and guest apartment. It’s one of fewer than two dozen homes in Manalapan with tunnel access to the ocean.

The Mackins paid $38.9 million for the property in 2020, the year the house was built. They purchased the estate after selling their Palm Beach mansion at 1480 North Lake Way to Sylvester Stallone for $35.4 million.

The latest trade of their Manalapan estate follows a string of pricey deals in the town, which is south of Palm Beach.

Earlier this month, private equity billionaire Randal Kirk sold his ocean-to-lake Manalapan estate for $62.5 million, less than half of the $134 million he listed it for in September. Brandt also represented the seller in that deal. Last month, billionaire WeatherTech founder David MacNeil sold a $3.6-acre oceanfront assemblage for $105 million, a record for land deals in Manalapan. Also in April, a mystery buyer bought two waterfront properties in a pair of deals totaling $62.6 million for a 2.6-acre assemblage.
