Rob Gronkowski: ~ $1.9 million, Boston
With all the cash he was earning as a professional footballer, Ron Gronkowski used some to get himself a Boston penthouse apartment located at the corner of the rooftop. This apartment is on the 6th floor so the view is nice. Ron managed to purchase it at $1.9M although the original price was $2.2M. It had a bit of history because it was made in 1890 using bricks for the walls. It offers two baths, two bedrooms, lots of parking space, a balcony, and a stylish kitchen. Ron had a role in the film America Violence in 2017. Through Instagram, he told the public of his retirement from pro football in March 2019.
