5+ Bedroom Homes for Sale in Key Biscayne: What to Know Before You Search

Beyond the Rickenbacker tollgate, tucked between two state parks, Key Biscayne functions as Miami's island village — a K-8 school and streets where children pedal to the beach. Ordinance limits the condo count and no new building has opened since 2014, which means the scarcity driving prices here is entirely real.

Narrowing Key Biscayne to 5+ bedrooms lands you in the large-format end, where homes suit multigenerational households, dedicated home offices and buyers consolidating two residences into one. In a market known for a family island village between two state parks, fifteen minutes from Brickell, bedroom count is the filter that maps cleanly onto real life — and this page keeps every property type on screen, so you can measure a 5-bedroom condo against a townhome or a house at the same price.

Frequently Asked Questions

What does a 5-bedroom home run in Key Biscayne?

The range is wide, because property type moves the price as much as bedroom count — a 5-bedroom condo, townhome and house in Key Biscayne can sit in entirely different bands. The live listings here show today's asking prices across all three; sort by price to bracket the market in seconds.

Do listed bedroom counts include dens and offices?

A legal bedroom needs a window and a closet, and MLS counts follow that rule — dens and offices are noted separately. If a flex room matters to you, tell us: plenty of Key Biscayne floor plans include a den that lives as an extra bedroom without being counted as one.

How do I arrange a showing in Key Biscayne?

Each listing on this page carries an inquiry form that goes straight to our brokerage — or reach us at +1 786-370-8570. We schedule private tours to fit your calendar and run live video walkthroughs for buyers relocating from out of state, with no obligation attached.
