Keystone Point

A 1950s dredged point in Biscayne Bay, inside a county guard district

About Keystone Point

Keystone Point is four recorded plats of about 118 acres on dredged ground in Biscayne Bay, laid out as Sections One, Two and Three and the Venetian Section, with a small commercial plat beside them. Most of the houses date from 1952 to 1959. Miami-Dade County created a security guard taxing district here by ordinance in 1989, covering roughly 880 units across sixteen separate plats, the Keystone Islands and Coronado Harbour among them. Before any of that, the base of the point was the Aviation Country Club, whose plats are still on the books underneath.

Averages are weighted as total dollars over total square feet. We calculate averages based on closed sales in the MLS for the past 12 months, as of September 1, 2026. Averages are based on properties that are listed or sold for $350,000 and greater. Additional reports at all price points are available here. Price-per-square-foot figures are rounded to the nearest dollar, up or down. Where fewer than 5 closed sales exist in the window, we report the count rather than an average.
