The five-bedroom, six-bathroom townhouse at 46 East 82nd Street wasn't always quite as grand as it is today; when the house went on the market back in 2014, it has a medical office on its ground floor. But the current owners (an anonymous corporation registered as 46 East 82ND Street LLC, because of course) picked it up for a song—$8.8 million—made some big changes, and now have it back on the market for a whopping $22.5 million. It's also available as a $100,000-per-month rental, if you're the sort of person who's into that sort of thing and have a ridiculous amount of money to spare. The owners gut-renovated the place, which explains the price hike: it now has a limestone-like exterior, a large staircase, a rear garden, and a full-floor master suite with a dressing room that's bigger than most people's bedrooms. Also included: "a solid mahogany door clad in black with a polished nickel handle—fashioned after the front door of London's Number 10 Downing Street."
