The William Kaufman Organization and an arm of Travelers Companies landed $65 million in refinancing for the 417,240-square-foot office tower at 747 Third Avenue.
The joint venture secured a $65 million leasehold mortgage, the Wall Street Journal reported.
The Singer & Bassuk Organization represented the owners.
The tower, built in 1972, covers the entire block of Third Avenue between East 46th and East 47th streets.
Kaufman pumped $17.3 million into renovating the building in 2012, and signed tenants such as Regus and four others to approximately 53,422 square feet.
