Williams Island's numbers right now describe a market that has slowed and repriced. The median sale sits at $840,000 with a median of $346.15 per square foot, but the year-over-year change of -28% is the figure that matters most — this is a market correcting off a higher base, not one holding steady. With only 13 closings in the window, each sale carries real weight in these figures, so treat the median and per-square-foot number as directional rather than precise.
A median days-on-market of 149 and a market heat score of 27 both point the same direction: this is currently a buyer-paced environment. Sellers here should expect longer marketing periods and price negotiation tied to condition, not urgency. Buyers get time to evaluate, but should also recognize that thin closing volume means comparable data is limited, so a private appraisal-minded read on any specific unit matters more than the aggregate stats.

Who Williams Island is best for.
Best for
- Buyers with flexible timelines who can wait through a marketing period well beyond a month
- Buyers comfortable negotiating on price given the recent year-over-year pullback
- Sellers who can price to current conditions rather than prior-year levels and accept a longer runway to close
Probably not for
- Sellers who need a fast transaction or are anchored to last year's pricing
- Buyers relying on a large, stable set of recent comparable sales to underwrite an offer
- Buyers or sellers expecting confirmed building amenities without independently verifying them
Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending July 20 of each year, from record-level MIAMI MLS closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($840K) IS the median in the snapshot above, and the move from 2025 ($1.17M) IS the -28.0% one-year change.
Windows contain 0 to 34 sales each (13 in the current window); every figure carries its sample size, and thin markets swing on single closings. Based on information from the Southeast Florida Multiple Listing Service (SEFMLS) or from MIAMI Association of REALTORS(R) for the period 2013 through 2026. Deemed reliable but not guaranteed.

The Williams Island buying strategy.
If we were buying in Williams Island today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Williams Island.
A market defined by patience, not pace
The median days-on-market of 149 is the clearest signal in this snapshot. Homes here are not moving quickly, and a market heat score of 27 confirms that current conditions favor buyers who can take their time rather than sellers looking for a fast transaction. Combined with a 28% year-over-year decline, the data suggests a market working through a repricing period rather than one in active recovery.
With just 13 closings in the tracked window, the median price of $840,000 and per-square-foot figure of $346.15 should be read as a snapshot of a thin sample, not a stable trend line. No community amenities were identified from current MLS listings, so buyers evaluating a specific unit should confirm building-level features and any association details directly rather than assuming them from market-level data.
The location and the amenities are priced into every listing in Williams Island. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a market this thin on closings and this slow on turnover, pricing a listing or evaluating an offer requires more than pulling a median. We look at the individual transaction history behind these numbers, not just the aggregate, so sellers price realistically for a 149-day-plus marketing runway and buyers understand what's actually driving the 28% year-over-year shift before they negotiate.
