Key Biscayne Condos for Sale
Find the Key Biscayne condo that fits your life, with the association, the fees and the offer understood before you commit.
Live BeachesMLS listings matching this search in Key Biscayne, Florida, updated throughout the day.
Condominiums make up most of the homes on Key Biscayne, and they sort into a few clear groups. The large oceanfront communities, Key Colony, the Commodore Club and the Ocean Club, are each several associations sharing grounds, so fees and rules change from one building to the next within the same community. Older buildings along Crandon Boulevard, Ocean Drive, Grapetree Drive and Galen Drive hold smaller apartments at the lower end of the island's range, and the Cape Florida Club near the state park mixes apartments with townhouses. Whichever you look at, read the budget, the reserve study, the milestone inspection and the leasing and pet rules before you offer, because on Key Biscayne the building often explains a price gap better than the unit does.
