A referee's deed is signed by a court-appointed referee to complete a sale ordered by a court.
The NYC Department of Finance lists Flatiron Owner LLC as owner of the tax lot, a class O4 office building, with a market value of $63,691,000 and an assessed value of $23,384,700 for fiscal year 2026/27.
ACRIS shows the building changing hands several times in five years, which is why a careful buyer or lender reads the full chain rather than the latest deed alone.
