Key Biscayne Condos for Sale under $500K

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 $500K is the entry to the Key Biscayne condo market — a segment that rewards knowing where the value actually sits. Known for a family island village between two state parks, fifteen minutes from Brickell, Key Biscayne at this ceiling is a trade-off between address, age and dues: an older building on a great block, a smaller plan in a newer tower, or more space a few minutes off the prime grid. This page keeps every Key Biscayne condo beneath $500K in one view so the best of them doesn't slip past.
