Luxury condo sales on Manhattan’s Upper East Side certainly tend to lean on the side of the grandiose. The latest addition to this trend is a co-op turned partial mansion at 828 Fifth Avenue. Of the 9 total apartments that exist within the property, 4 are now on sale for the grand total of 72 million dollars. As a whole, the property would include 2 floors of the co-op, a maisonette duplex, and a penthouse complete with terrace and rooftop. The mansion is billed as potentially one of the greatest pieces of real estate that exists in Manhattan, a title that would live up to the price that this Upper East Side mansion carries.
