18555 Collins Avenue Cond
Condos for Sale in Sunny Isles Beach, FL

18555 Collins Avenue Cond market snapshot (as of September 12, 2026): the median sale price is about $4M ($1112 per sq ft over the trailing 12 months of closed sales), and a median 249 days on market for closed sales. The trailing-12-month median is down 47% from the prior 12 months, computed from record-level MIAMI MLS closed sales (11 closings in the current window).

This is a single oceanfront condominium on Collins Avenue, trading at a median price of $4,200,000 with pricing driven by unit line and finish rather than by amenities marketed at the community level.

With a median days-on-market of 249, this is not a building where units clear quickly on listing alone. The math favors sellers who invest in presentation and price to the current per-square-foot benchmark, and buyers who are willing to negotiate on unrenovated inventory rather than compete for the rare turnkey listing.

Year-over-year movement of 2.4% suggests a market that is holding its level rather than swinging sharply in either direction. Combined with a thin closings count of 11 over the recent window, it's a market where individual unit condition and line matter more than any broad trend line — due diligence on the specific unit is doing most of the work here.

In a building with this few closings, generic comps do not hold up — we track unit-by-unit sales, floor premiums, and renovation status to price and negotiate accurately rather than relying on a building-wide average that can mislead in either direction.
