This is a lower-volume Miami-Dade condo market where price is set unit-by-unit rather than by a predictable per-square-foot floor, and current MLS data does not surface a defined amenity package for the building.

The gap between the median price and the median price per square foot suggests unit mix and finish quality do a lot of the work here — this is a building where the listing photos and the recent renovation history matter as much as the tax record square footage. Buyers comparing two units on paper should expect the in-person walkthrough to change the math.

A median of 56 days on market combined with a moderate heat score of 41 signals a market that rewards patience on both sides. Sellers who price to the recent comp set tend to move; sellers who chase the year-over-year gain risk sitting past that 56-day median. With only 11 closings feeding the current window, every new contract shifts the picture, so the trend should be read as directional rather than fixed.

In a building with this few annual closings, the last two or three sales — not a broad average — set the real asking price, and knowing which of those sales was a renovated unit versus a dated one is the difference between an accurate offer and an overpay. We track those individual comps and the building's condo documents so you are negotiating from the same information the listing agent has, not just the median.
