Luxury Homes for Sale in Key Biscayne — A Local's 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.

The luxury tier in Key Biscayne plays by its own rules — many of the best properties trade quietly, negotiations run on terms as much as price, and the buyer pool is global. Known for a family island village between two state parks, fifteen minutes from Brickell, Key Biscayne sits on the itinerary of international capital, and representation matters: we track off-market availability alongside everything listed on this page.

Frequently Asked Questions

Are there off-market luxury homes in Key Biscayne?

Always. A meaningful share of the top of the Key Biscayne market trades privately — sellers who want discretion, buildings where owners talk to each other first. Tell us your criteria and we'll canvass beyond what's public; that's standard practice at this tier.

How do international buyers purchase in Key Biscayne?

Foreign nationals buy Florida property freely — cash or through foreign-national loan programs, often via an LLC for privacy and planning. FIRPTA affects the eventual sale, not the purchase. We coordinate with tax counsel so the structure is right from day one.

How do I tour a home in Key Biscayne?

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.
