The Miami-Dade Property Appraiser lists 319 residential folios under the subdivision 1000 ISL BLVD WILLIAMS ISL CONDO, built 1990. The declaration also carries 36 folios that are not homes (34 PS, 1 REFERENCE FOLIO, 1 PSO). Miami-Dade classifies deeded parking and storage under the same residential code as a residence, so a count taken straight from the roll overstates this building by that amount.
The cheapest foot on the island
Pooled across qualified sales since 2023, 1000 Island Boulevard trades at $316 per square foot on a median sale of $450,000. Every other tower in the community is more expensive per foot, and the top of the ladder is 2.3× higher. That gap is the single most useful thing a Williams Island buyer can know, and it is not published anywhere else because it requires pulling all seven towers from the county roll and pricing them on the same basis.
The discount is not explained by size. The median home here is 1,520 square feet and the roll records 3 one-bedroom, 172 two-bedroom, 143 three-bedroom and 1 four-bedroom. That is a conventional family-sized mix, not a studio building.
A 2012 record nothing has touched
The highest qualified sale on the roll is $3,300,000, recorded 27 January 2012, for a 4,560 square-foot residence — $724 per foot. Fourteen years later nothing in the building has matched it, and current pricing is running at roughly 44% of that figure per foot.

What to check before you sign
- Confirm the folio, not the unit number. Ask for the folio and read its own sale history and assessment. Building averages hide a 4.8× range in home size here.
- Ask whether parking and storage are deeded separately. In this community they frequently are — 183 folios across the seven towers — which means they carry their own assessment and may or may not convey.
- Ask the association for the milestone inspection status and the reserve study. These are 1990 buildings in Miami-Dade and fall inside the county’s recertification programme.
- Check whether any comparable you are shown was a multi-parcel deed. A single sale covering two combined residences will look like a record per-foot price if it is divided against one folio.
Frequently asked questions
Why is 1000 Island Boulevard cheaper per square foot than the rest of Williams Island?
The county record shows the gap but does not explain it. What it does rule out is a size effect: the median home is 1,520 square feet with a conventional bedroom mix, so this is not a small-unit building being compared against large ones. Age is the visible difference — it was completed in 1990. Treat the spread as a fact to ask the association and your agent about, not a valuation conclusion.
How many homes are at 1000 Island Boulevard?
The county roll records 319 residential folios, built 1990. A further 36 folios in the same declaration are deeded parking, storage or cabanas classified under the same residential code; they are not homes.
What have homes at 1000 Island Boulevard sold for recently?
Pooled across qualified sales since 2023 the median is $450,000, or $316 per square foot. By year the median per foot runs $315 in 2023, $321 in 2024, $343 in 2025, $297 in 2026. There were 68 qualified sales in four years, so treat single-year figures cautiously.
Is 1000 Island Boulevard a good value compared with the rest of Williams Island?
On price per square foot it ranks 1 of the seven Island Boulevard towers, at $316 against a community range of $316 to $740.
