History

In 2007, Macklowe Properties bought the Park Avenue Tower along with five other buildings in New York for $7 billion from the Blackstone Group, which had acquired the building by acquiring Equity Office Properties, the previous owner. One year later, in the summer of 2008, the building, along with the 21-story 850 Third Avenue, was sold to Shorenstein Properties for $930 million, as Macklowe Properties faced challenges during the credit crisis. At the end of 2013, it was announced that Grocon wanted to buy the Park Avenue Tower for $500 million, which later became $775 million. In the spring of 2014, that deal was canceled when Grocon could not raise sufficient funding. Grocon had secured a $530 million loan from Jones Lang LaSalle, but could not obtain further funding. In July 2014, the building was sold again to Blackstone Group for $750 million. Blackstone resold it to SL Green in October 2025 for $730 million.
