This classic prewar building, built in 1914 by W. L. Rouse in the Italian-Renaissance-palazzo style, was converted to a cooperative in 1950. It has 46 units across 12 floors and is located on the east side of Park Avenue between 71st and 72nd Streets. The full-service white-glove building offers a gym and storage. A 2% flip tax is payable by the buyer, and 40% financing is allowed.
