Key Biscayne Condos for Sale under $1M

Beyond the Rickenbacker tollgate, tucked between two state parks, Key Biscayne functions as Miami's island village — a K-8 school and streets where children pedal to the beach. Ordinance limits the condo count and no new building has opened since 2014, which means the scarcity driving prices here is entirely real.

Under $1M covers the broad middle of the Key Biscayne condo market — the band where most move-up buyers and serious second-home shoppers actually transact. Known for a family island village between two state parks, fifteen minutes from Brickell, Key Biscayne at this ceiling opens real choice: newer two-bedrooms, well-run buildings with full amenities, and the occasional larger plan in an older tower whose dues undersell its address. This page holds every Key Biscayne condo beneath $1M, sorted so the range is easy to bracket.
