Luxury Condos for Sale in Key Biscayne
Full-service and boutique condo residences in Key Biscayne priced above $1 million, with live availability.
Key Biscayne is an island village connected to Miami by the Rickenbacker Causeway — beaches, Crandon Park, Bill Baggs park and a village center that feels like a small town.
Island inventory is limited and fiercely held — families buy for the schools, the safety and the beach club lifestyle. Condominiums along the ocean and bay offer the entry point.
Before you fall for a Key Biscayne condo, read the building rather than the unit: reserve funding, the last special assessment, milestone inspection status, insurance renewal history, and what the monthly fee actually includes — in many South Florida buildings it already covers the master insurance policy, which changes your true cost of ownership. Harbor Drive and the Mashta area offer protected bayfront dockage; the island's west side faces Biscayne Bay with the Miami skyline behind it.
