How We Got This
  • Comps: the closest Brooklyn plans on size, $/SF and launch date, within 2 miles when possible.
  • Figures: each building's own offering plan, filed with the NY Attorney General. Nothing is estimated.
  • Checked: a price list publishes only when its math adds up, and building pages cite the plan pages.
  • Labels: In line is between the comps; Below/Above peers is past both by up to 15%; Lowest/Highest by more.
