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.

Closingsfirst and latest recordedMay 31, 2022 – Dec 29, 2023

Sales recorded with the Department of Finance (ACRIS) through Mar 31, 2026: deeds, or transfer tax filings for a building on leased land, of $10,000 or more. A home's first sale since the plan was filed is the sponsor's closing; resales aren't counted. Closing prices are compared with the same home's Schedule A price, as first offered; a deed covering more than one home isn't compared. Amendments often change prices before a home closes, and a deed that includes parking or storage counts its full price. ACRIS records a sale weeks after closing, so recent contracts don't appear yet. Every building's sales.
