What Homes in Williams Island Are Selling For

46 homes closed in Williams Island in the last 180 days at a median of $1,269,000, or $584 per square foot, after 99 days on the market on average, and sellers achieved 92.4% of asking. The median is up 29.5% on the same period a year earlier. With a small number of sales a single large or small home can move a median, which is why a valuation works from the individual closings rather than from this figure.

What Buyers Pay For in Williams Island

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. Those are the things a Williams Island buyer compares from one home to the next, and they are what separate a sale at the top of the range from one at the bottom.

Williams Island Against the Aventura Average

A Aventura-wide figure blends every neighborhood, every property type and every condition. Williams Island has its own buyers and its own price range, so a home here is valued against Williams Island closings first and against the nearest comparable streets only when there are too few. There are 88 homes for sale in Williams Island today at a median asking price of $797,000, about 11.5 months of supply: that is the competition a new listing is priced against.
