This particular building is a lot more colorful than the Comptroller lays out here. It was bought in '17 at the height of Chinese skyscraper fever by "gray rhino" HNA for $2.2B. When HNA started feeling liquidity pressure, Manhattan giant SL Green wriggled into the capital stack, eventually taking over the distressed property when HNA went under. So yes, it's an indication of big tailwinds in leasing. But it's also a tale of some elite capstack-sniping.
