List your Key Biscayne home on the MLS from $99 — fully syndicated to Zillow, Realtor.com and 100+ sites. Keep your equity instead of paying a 6% commission. Start with a free, instant value estimate for your address.
Key Biscayne is an exclusive island village off Miami connected by the Rickenbacker Causeway — a tight-knit, affluent, internationally flavored community of luxury condos, the guard-gated Ocean Club, and multimillion-dollar single-family homes. As of mid-2026, Key Biscayne sales commonly run $2,000,000 and up, among the highest in Miami-Dade.
At island prices, a 6% commission is extraordinary — roughly $120,000 on a $2M sale. A flat-fee MLS listing gives your Key Biscayne home the same luxury MLS, Zillow and Realtor.com exposure for a flat fee, with broker support, so you keep that enormous equity.

Key Biscayne is split between luxury condos and high-end single-family homes, each with its own factors. Condo buyers scrutinize the post-Surfside milestone inspection, SIRS reserve study, reserves and assessments — older oceanfront towers especially. Single-family island homes carry flood-zone, elevation and wind-insurance considerations (it's a barrier island) and often waterfront dock/seawall details. The buyer pool is heavily international and cash, so full portal syndication and premium photography/video (VIP plan) that reach a global audience are essential.
Every plan lists your Key Biscayne home on the MLS and syndicates to Zillow, Realtor.com and 100+ sites. No listing commission, ever.
Key Biscayne sits in Miami-Dade County, and Miami-Dade is one of only seven Florida counties where the buyer customarily selects the closing agent and pays for the owner’s title policy. Across most of the state that cost falls to the seller. It is negotiable and the contract controls, but a net sheet built on statewide averages will get your bottom line wrong.
Documentary stamp tax on the deed in Miami-Dade County is $0.60 per $100 plus a surtax on property that is not single-family. That is the one Florida county that differs from the statewide rate, which is why a national closing cost calculator misreads a Miami-Dade sale in both directions. Your listing runs on the MIAMI Association of Realtors MLS and syndicates from there to Zillow, Realtor.com, Redfin and the other major portals.
Key Biscayne is an island reached by causeway, and that changes both the buyer pool and the title picture. Waterfront parcels raise questions about where your legal description ends and state-owned submerged land begins, and whether any dock or seawall is permitted. Those surface in the search, and they are cheaper to answer before you list.
