How this is drawn: a unit's floor and line come from its MLS unit number alone (5614 is floor 56, line 14). A cell exists only where the MLS has recorded a listing, a closing or a lease; a blank means no record was seen, not that no unit exists. Column widths follow each line's median recorded living area. Pre-construction towers and buildings with a thin record have no drawing.

Built in 1965, Islander is a 10-story mid-rise at 1255 Collins Ave in South Beach. The Miami-Dade Property Appraiser lists 63 residential units, averaging 620 SF of living area.

On November 2, 2026, three units were listed for sale, asking $295K to $340K (median ask $505/SF across 3 listings). One sale closed between November 2, 2025 and November 2, 2026 at $310K, $546/SF. The year before saw two closed sales. The MLS holds 24 closed sales here going back to 2019; among years with three or more sales, 2024 set the high at a median $573/SF.

Five units were offered for rent at $2,075 to $2,600 a month. Seven leases were signed over the same 12 months, at a median $2,500 a month (range $2,400 to $2,800). Leases outnumbered sales 7 to 1 over that year, so renters are a large share of who lives here.

About 35% of the residences are owner-occupied according to county records, which points to an investor-heavy ownership base.

FEMA flood zone

AE

Inside FEMA's Special Flood Hazard Area. A federally backed mortgage requires flood insurance here.

What the zone means
  • The 1% annual chance ("100-year") flood area, with a base flood elevation set.
  • Base flood elevation 8 ft (NGVD29).
  • The zone is a map line, not a premium. Ask the association for its master flood policy, and get a flood quote for the specific unit before you commit.

Milestone structural inspection

Turned 30 in 1995

The statute's first deadline for a building this age was December 31, 2024, then every 10 years.

What the deadline means
  • Based on year built 1965 (county record). The statute counts from the certificate of occupancy date, which can differ.
  • The association must give every owner the inspector's summary. Ask for it, and for the structural integrity reserve study, before you commit.

Fla. Stat. § 553.899(3) ↗ and Miami-Dade recertification ↗, read Oct 9, 2026. What the deadline means for buyers
