These figures are the market's closed sales as the MLS records them: this building's for a unit, a gated community's for a home inside one, and otherwise the sales of this kind of property in the home's market — for a home at $2,000,000 or more, only that market's sales from that price up. Which of these it is, is said above the figures. No snapshot is drawn from fewer than 5 sales of the last twelve months, and a median price per SF is stated only from 3 sales that state a living area. They are not sales by Julian Acosta, they are not an appraisal, and they say nothing of this home's price.
These are the public schools whose attendance zone holds this listing's location, as Miami-Dade County publishes the zones. A zone is not a guarantee of enrollment, the district can change it, and a listing's point on the map can sit a few meters from its lot: confirm the school with Miami-Dade County Public Schools before you rely on it. Distances are straight lines. The page states no rating of any school.
