The Ritz Tower's units were sold at rates ranging from $7,200 for a single room to $43,200 for five rooms. Most of the cooperative units were two-bedroom apartments with four total rooms. There were also studio units and one- to three- bedroom apartments with a varying number of rooms. The old 19th and 20th story duplex was retained as one unit. The Ritz Tower was one of several New York City apartment hotels that had converted to cooperative operation in the mid-20th century. Le Pavillon, one of the first authentic French restaurants in the U.S., moved to the Ritz Tower from 55th Street in 1957, after the renovation was completed. The New York Savings Bank placed a ten-year, $2.74 million mortgage on the building in September 1958. The New York Bridge Whist Club and the Cavendish Club, two contract bridge clubs, were among the groups housed in the Ritz Tower at this time.
