Condos for Sale in Key Biscayne, Florida

Typically building insurance, staff, amenities, water and reserves — which is why a condo's fee isn't comparable to a house's costs until you add the house's own insurance, maintenance and services. High-service buildings charge more and deliver more; every listing here shows the exact monthly fee.

Florida now requires milestone structural inspections and funded reserves for aging condominiums. It has been the defining diligence issue since 2021: buildings that completed inspections and funded reserves are the safer purchases, and we pull each building's status before you commit.

Every listing on this page has an inquiry form that reaches the broker directly — or call +1 786-370-8570. We arrange private showings around your schedule, including video tours for out-of-town buyers, and there is never an obligation.
