Market Context

Williams Island 4000 Building has completed-year closed-sale history from 2017 through 2025 in the market statistics, with 99 recorded condo sales, or about 11 sales per year. That gives buyers a useful resale sample, but individual unit differences still need to be adjusted carefully. The busiest year in the series was 2021 with 31 sales, while the quietest was 2018 with 5. Recent completed-year sales volume is below the long-term average. The gap between the busiest and quietest years also shows why buyers should separate building demand from broader market-cycle timing.

The completed-year price-per-square-foot history for Williams Island 4000 Building ranges from about $240/sqft to $500/sqft, with an average near $344/sqft across the years shown. That wide valuation band means unit-specific factors can materially change the right price range. The last completed year in the series is higher than the first, moving from $257/sqft in 2017 to $414/sqft in 2025. The recent completed-year price-per-square-foot average is above the long-term average. Average closed price over the same completed-year period was about $715,264, but that number should be read by bedroom count, size, view, and renovation level.

Bedroom-level statistics also help explain value at Williams Island 4000 Building: 2 Beds and 3 Beds units have the broadest historical comparison set, while 4 Beds+ around $2,164,125 and 3 Beds around $1,068,680 represent the higher average closed-price tiers in the chart data. The segment is useful, but buyers should still check whether the underlying sales were similar in size, view, and condition. Buyers should compare units within the same bedroom count before deciding whether a listing is expensive or well positioned. Williams Island 4000 Building also has long-term rental positioning with a 12-month minimum lease and up to 1 rental per year, which should be read together with the long-term sales data. That points to a more traditional ownership profile, so long-term tenant quality, association approvals, and carrying costs matter more than short-stay turnover.
