Private Islands in South Florida: A Buyer’s Guide to the Keys, Biscayne Bay, and the Island-Address Alternative

Private-island shopping in South Florida sits at the intersection of romance and regulation. Inventory exists, but it is thin and often marketed through portals and boutique channels; pricing spans widely, and the true differentiator is not just shoreline or sunset exposure, but what you can legally build, dock, insure, and maintain. This guide outlines the micro-markets most often associated with “island living” in the Florida Keys and Biscayne Bay, then translates the state’s ownership and permitting realities into a due-diligence framework. Finally, it offers a pragmatic option for buyers who want the island feel with a more predictable operational burden: the island-address residence in Miami’s most refined waterfront buildings.

Miami vs. the Caribbean: The New Second-Home Equation for Ultra-Wealthy Buyers

Miami’s second-home story has shifted from lifestyle upgrade to strategic positioning. In recent residential real estate analysis, Miami was ranked as the global epicenter for ultra-wealthy second homes, with roughly 13,200 ultra-high-net-worth individuals reported to own second homes here. At the same time, tax policy headlines, including a proposed California “Billionaire Tax Act” framework described as a one-time 5% excise tax on worldwide net worth above $1 billion, have sharpened the contrast between U.S. metros and offshore alternatives. For South Florida buyers, the real comparison is not “Miami or an island.” It is “Miami plus an island,” or “Miami as the operational base with optionality elsewhere.” The Caribbean remains compelling for privacy, seclusion, and residency pathways in certain jurisdictions. Yet Miami’s advantage is institutional: depth of healthcare, market liquidity and transparency, aviation and marine services, and a year-round social and cultural calendar. This is why the conversation has become less about pure escape and more about building a second-home portfolio that performs under scrutiny, whether that scrutiny is financial, familial, or geopolitical.
