These rare South Florida mansions have water on both sides. Where to find them

South Florida real estate brokers say the region’s rarest trophy homes offer waterfront on two sides — ocean in the back, Intracoastal in the front.

A stretch of Hillsboro Beach in Broward County is the epicenter, while Miami-Dade largely lacks the geography for it.

Here are key takeaways:

Hillsboro Mile, a 3.2-mile stretch of A1A in Hillsboro Beach, holds 47 single-family estates that span the barrier island’s roughly 900-foot width, with the Atlantic on one side and the Intracoastal Waterway on the other. Some mansions include private tunnels under A1A so residents can reach their docks without crossing the road.
The priciest 2026 residential sale in Broward County so far was tech and media executive Mason Paul Slaine’s $42 million July purchase of 1107 Hillsboro Mile, a 10,101-square-foot estate on 1.38 acres, according to property records.
Hillsboro Beach Mayor Dawn Miller, who moved to the mile from Miami Beach’s La Gorce neighborhood during the pandemic, said the town has been “pretty much under the radar until recently” and credits the ocean-to-Intracoastal geography for drawing new interest.

Similar double-waterfront estates exist in Manalapan, where Larry Ellison and David MacNeil paid a combined $67 million in June for a four-acre oceanfront lot, and on Jupiter Island in Martin County.
Miami-Dade lacks these estates partly because of preservation: In the 1960s, Miami News editor Bill Baggs campaigned to protect the southern tip of Key Biscayne, which became Bill Baggs Cape Florida State Park in 1967.
