Square footage is recorded for only 2 of these 3 sales (67%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.
This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Beekman instead.
