2 units in the record sit outside this grid (8FS, 11AN): penthouse, townhouse or ground-level numbers, or lines seen only once or twice.

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.

The read on Mar Azul.

Activity as of Nov 2, 2026
  • Resale +74%. The median closed price moved from $522/SF in 2020 (6 sales) to $910/SF in 2026 (4 sales), the first and last years with three or more recorded sales.
  • Gross rental yield 6.7%. A year of rent at the median $5.06/SF/mo (4 leases) against the median $910/SF sale (4 sales), both over 12 months, before HOA, taxes and vacancy.
  • Asks run +10% against closings. Sellers ask a median $1,001/SF (3 listings) against $910/SF closed (4 sales, 12 months). That gap is negotiation room. Bring the comps.
  • Sells in a median 83 days. Days on market across the 4 sales closed in the last 12 months.

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 2004

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 1974 (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
