In connection with the sales of residential condominium units at 77 Greenwich for the three months ended March 31, 2022, we recorded gross sales proceeds of approximately $6.3 million. Units that closed during 2022 were generally lower priced, smaller units on the building’s lower floors, many of which entered into contract during the height of the pandemic. These units were completed first and were covered by the initial TCOs. Getting these units under contract allowed us to obtain approval from the New York State Attorney General and therefore start the closing process on residential units.
