Location: Hillsboro Beach, Fla.
The Skinny: Set on aptly-named "Millionaires Mile," this 20,000-square-foot seaside sanctuary might be the pick of the lot. Hillsboro Beach might not be the first name in pricey Florida real estate, but with a population of less than 2,500, this sleepy strip of sand offers a true escape compared to the snowbird crowds of nearby Boca Raton and Palm Beach. Boasting 2.8 acres—and fronting on both the Atlantic and Intracoastal Waterway—this property comes equipped with a deep-water yacht dock, infinity swimming pool, seven bedrooms, three elevators, and a nine-bay underground garage. And while the stark interiors might not be for everyone, they're a soothing respite from the overwrought Italianate standard in South Florida. All those clean lines don't come cheap, though; a $40M price tag makes this one of Florida's most expensive.
