Williams Island Homes for Sale in Aventura

Gated island towers with a marina on the Intracoastal. Every home currently for sale in Williams Island, Aventura, straight from BeachesMLS and updated throughout the day.

Williams Island is a guard-gated island community in the Intracoastal Waterway on the east side of Aventura. Its towers take their names from their Island Boulevard addresses, the 1000, 2000, 2800, 3000, 4000 and 7000 buildings, built from the mid-1980s to the mid-1990s, alongside the Mediterranean Village condominium of 1988 and 1989 and Bella Mare, completed in 2005. Listings describe marina slips, restaurants, a spa and tennis on the island; ask how the club and the marina are paid for, and what ownership includes, before you compare two units.

Dockage, Water and the Club at Williams Island

In a boating community the dock is worth as much as the house. For every home in Williams Island we confirm whether the dockage is private, deeded or a club slip, the length and beam it takes, the water depth at mean low tide, the height and number of bridges on the route to the inlet, the age and condition of the seawall and the dock, and the flood zone and elevation that set the insurance. Where a yacht or country club sits inside the community, we also confirm whether membership comes with the home and what it costs to join and to keep.

Selling a Home in Williams Island

Buyers for a home in Williams Island compare it with the other homes in the community first and with the rest of Aventura second, so pricing starts from the closed sales inside Williams Island that match your home's section, lot, water frontage and dockage, age and renovation. We market to the buyers who ask for Williams Island by name, arrange private showings when discretion matters, and prepare the association and club documents buyers will ask for before the first showing.

Williams Island: Frequently Asked Questions

How much do homes cost in Williams Island?
Homes in Williams Island sold at a median of $1,269,000 over the last six months, and the 88 homes for sale today are asking a median of $797,000. Prices vary by section, lot and renovation, so we price every home from the closed sales that match it. These figures refresh daily from the MLS.
Is club membership required to buy a home in Williams Island?
Membership terms are set by the club and change over time, so we confirm them for the specific home before you offer: whether membership comes with the purchase or is optional, the membership categories, the equity or initiation contribution and any refund terms, annual dues, food and beverage minimums and planned capital assessments. Some South Florida clubs require membership of every homeowner and others offer it separately.
What size boat can I keep at a home in Williams Island?
It depends on the dock, the water depth at low tide and the bridges between the home and open water, all of which change from lot to lot in Williams Island. We confirm the dock length, the depth at mean low tide and the clearance of every bridge on the route for each home we show, so you know before you offer whether your boat, or the one you plan to buy, will fit.
How long does it take to sell a home in Williams Island?
Homes that sold in Williams Island over the last six months took 99 days on average to go under contract and closed at 92.4% of the asking price. Homes priced from the community's own recent sales sell faster; the average is pulled up by homes that started too high.
Can I rent out a home in Williams Island?
The association and the club decide. Many Aventura communities set a minimum lease term, limit the number of leases a year, require tenant approval, or require an owner to hold the home for a period before leasing. We read the governing documents for the home you are considering and tell you exactly what they allow before you buy.
What is my Williams Island home worth?
Request a free valuation and a BreakThru broker builds it from the closed sales inside Williams Island that match your home's section, lot and renovation, not from a citywide median. For a listing decision we prepare a full comparative market analysis and a marketing plan built for the buyers who search for Williams Island by name.
