When it comes to Key Biscayne real estate, buyers find a rare mix that speaks to true coastal living. Architectural styles range from coastal-modern smart homes and classic Mediterranean villas to refined waterfront condos with amenities that rival five-star resorts. Single-family homes typically range from about $3 million to $30 million, depending largely on whether the property is waterfront or inland.

For condos, 1- to 2-bedroom residences generally fall between the low $400Ks and $4 million, while 3-bedroom and larger units range from roughly $1 million to the mid-$10 millions in the most coveted oceanfront buildings.

Notable residential options include Oceana Key Biscayne, Grand Bay Residences, The Ocean Club, and Ritz-Carlton Residences Key Biscayne.

High-end features often include private docks, infinity-edge pools, panoramic terraces, concierge services, spa amenities, beach access, tennis courts, and fitness centers. This market attracts buyers who understand real quality—where privacy, wellness, and lasting value are part of everyday life, not marketing promises.
