Key Biscayne is the barrier island where a U.S. president once kept his Winter White House, and where residents today enjoy a resort-town pace just four miles from downtown Miami. Connected to the mainland solely by the Rickenbacker Causeway, the island offers wide bike paths, salt air, and a low-rise skyline unlike anything else in South Florida. Virginia Key sits between the island and the city, softening the transition and adding a layer of natural calm. Crandon Boulevard anchors the main strip of dining and shopping, while state parkland caps both ends of the island.
Rental options lean toward upscale waterfront condominiums, mid-rise apartment communities with bay or ocean views, and single-family rental homes on quiet residential streets. Spanish Revival, ranch-style, and contemporary architectural styles are all represented across the rental stock, regardless of the type.
The local economy draws on tourism, marine industries, and real estate, while Miami's full job market sits a short causeway crossing away. The northern two-thirds of the island operated for decades as the largest coconut plantation in the continental United States before giving way to the parks and neighborhoods that define the island today.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
