Key Biscayne, FL Real Estate Guide

Key Biscayne is Miami's island village — past the Rickenbacker tollgate, between two state parks, with a K-8 school and streets where kids bike to the beach. Condo supply is capped by ordinance and the last new building arrived in 2014, so the market trades on genuine scarcity.

Buying a Home in Key Biscayne

Buying in Key Biscayne starts with understanding what drives its market: a family island village between two state parks, fifteen minutes from Brickell. Benchmark the segment you're shopping with the bedroom and property-type tables above, then open the live map search to see everything currently available — every listing links straight to full photos, details and an inquiry line to a licensed Florida broker.

Financed purchases in South Florida typically close in 30–45 days, while cash can close in as little as two weeks. Condo purchases usually add an association-approval step, and properties near the water carry insurance considerations worth pricing before you offer — both are routine in Key Biscayne transactions when planned early.

Renting in Key Biscayne

Rentals move faster than sales — well-priced Key Biscayne units are often signed within weeks, and most annual leases require first month, last month and a security deposit up front. The rent tables above show what tenants actually committed to by bedroom count over the last year; the live rental search shows every home and condo currently offered.
