A developer and healthcare mogul from Old Westbury purchased the Erchless estate at 75 Post Road for $21 million, making it Nassau County’s priciest sale of 2024. This 92-acre property includes a 16,000-square-foot mansion with 7 primary bedrooms and 12 bathrooms. The buyer plans to use the estate personally, possibly for events like a family wedding. The estate also features extensive grounds, including greenhouses and barns. Previously owned by Howard Phipps Jr., a descendant of steel magnate Henry Phipps Jr., the mansion had been in the family for nearly a century.
