Live BeachesMLS listings matching this search in Key Biscayne, Florida, updated throughout the day.
Two calendars feed the new listings on Key Biscayne. Oceanfront apartments in Key Colony, the Commodore Club and the Ocean Club draw seasonal buyers in the winter months, while families shopping for a house on the village streets often sign contracts in late spring, before the school year begins at the island's public school. A newly listed house should be read as land and building together: ask for the survey, the elevation certificate and whether it is an original early fifties home or an elevated rebuild. A newly listed condo calls for the budget, the reserve study and the milestone status of its own association, since a community such as Key Colony holds several. With one causeway on and off the island, plan to see several Key Biscayne listings in a single visit.
