Key Biscayne Luxury Homes for Sale

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.

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.

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.
