Costa Brava rises 22 floors at 11 Island Ave in South Beach and was completed in 1972. The Miami-Dade Property Appraiser lists 214 residential units, averaging 1,454 SF of living area.
On November 2, 2026, three units were listed for sale, asking $699K to $1.4M (median ask $681/SF across 3 listings). Eight sales closed between November 2, 2025 and November 2, 2026, from $659K to $3.8M, a median $690/SF, after a median 103 days on the market. In the 12 months before that, 10 sales closed at a median $874/SF, so the median fell 21%. The MLS holds 84 closed sales here going back to 2019; among years with three or more sales, 2025 set the high at a median $874/SF. That 12-month median ranks 39th of the 83 South Beach buildings with at least three sales in the same window. Two-bedrooms made up 14 of the 18 sales in the last 24 months, at a median $1,170,000.
Two units were offered for rent at $6,200 to $7,500 a month. 16 leases were signed over the same 12 months, at a median $6,500 a month (range $3,500 to $12,500). Leases outnumbered sales 2 to 1 over that year, so renters are a large share of who lives here.
About 59% of the residences are owner-occupied according to county records.
