It appears that Ian Reisner and Mati Weiderpass of Parkview Developers have sold one of their Southmoor House penthouses. The 17-floor building serves as more than just home to the Out Hotel developers. It’s also headquarters for their company. And like true developers, they own a big chunk of the building, making them one of the co-op’s biggest shareholders. While the newly troubled pair seems quite committed to their own symmetrical pad—turning down a $15.5 million cash offer a few years back without batting an eyelash—that doesn’t stop them from making serious bank on some other units. And you won’t hear us complaining, because that means we get to check out this 3BR/3BA penthouse.
