Williams Island

It's a private, guard-gated island community where the vast majority of homes — 80 of the 86 currently active — are waterfront, so the appeal is a secure, resort-style setting on Biscayne Bay. It suits buyers who want low-maintenance high-rise living with marina access over a traditional single-family neighborhood. Nearby North Miami Beach homes for sale offer more variety if you want to compare.

It's a premium address, with a median list price of $867,500 and an average of $570 per square foot. That said, the range is broad — from $340,000 at the entry level up to $13,750,000 — so there's more flexibility than the reputation suggests. Of the 86 active listings, 38 are priced above $1M.

The median list price is $867,500 against a median home size of 1,885 square feet, working out to roughly $570 per square foot on average. Over the last 12 months, 82 homes sold at a median price of $1,012,500. The gap between list and sold medians reflects how much the high end pulls the numbers around.

There are 86 active listings and 82 sales in the past year, with homes taking a median of 122.5 days to sell. Sellers are averaging 93% of asking, which signals a buyer-friendly pace where negotiation is expected. You can track new inventory as it hits on the live map.

The median property tax here runs about $7,927 per year. HOA figures aren't reflected in the current data, but in a guard-gated high-rise community like this you should budget for meaningful monthly association dues covering security, amenities and building upkeep — always confirm the exact figure per building before you write an offer.
