LAKE VILLA TWO CONDO

4+ Bedroom 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.

Filtering Key Biscayne to 4+ bedrooms puts you in the large-format end of the market, where homes serve multigenerational households, home offices and buyers consolidating from 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 search that maps to real life — and this page keeps every property type in view so you can weigh a 4-bedroom condo against a townhome or house at the same budget.

Frequently Asked Questions

What does a 4-bedroom home cost in Key Biscayne?

The spread is wide because property type matters as much as bedroom count — a 4-bedroom condo, townhome and house in Key Biscayne can sit in different price bands entirely. The live listings on this page show today's asking prices across all three; sort by price to bracket the market in seconds.

Do bedroom counts in listings include dens and offices?

Legally a bedroom needs a window and closet, and MLS counts follow that — dens and offices are listed separately. If a flexible room matters to you, say so: many Key Biscayne floor plans carry a den that works as the extra bedroom without being counted as 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.
