50 East Chestnut one of the city's most luxurious and pricey towers and this 37th floor unit is a great example of what the building has to offer. Last year, the building had a median sale price of just under $3 million, making it the fourth most expensive residential tower in Chicago. It's not just the high-end finishes and amenities that make this tower exclusive, it's the fact that it only has 34 total units, with each occupying a full floor. Expect all of the bells and whistles with this one, as the listing agent indicates that it features Calacatta marble, walnut floors, Venetian plaster walls and imported appliances. How refined. This one will set you back exactly $4 million and an additional $2,676 per month in assessments.
