In the city, I couldn't help but notice the One57 building. Since it stands over 1000 feet above Central Park, it's hard for anyone to miss. Personally, I'd be afraid to live in a 90 story residential, it's probably just me.
It's nicknamed the "The Billionaire Building" for a good reason - no one else could afford to live there! Early last year, one of the penthouses closed for over $100 million. It was the most expensive apartment ever sold in NYC.
Costs like that are why I'm escaping the city!
