There’s no shortage of ultra high-end inventory on the market at the moment, and the latest property to join the fold is a 5,600-square-foot penthouse on the 58th floor of the Waldorf Astoria. And with a listing price of $12.5 million, the full-floor penthouse has become the seventh most expensive residential property for sale on the MLS. While there are no photos included in the listing, there are some details about the place. It’s got private elevator access, 500 square feet of terrace space, and of course, great views of the city. Three garage parking spaces are also included in the asking price. And the monthly assessment on a place like this? You’re looking at $6,000 per month.
