What do you do when you're a retired boxer with more money than you can count? Buy a $7.7 million mega mansion in Miami Beach... in cash.

According to the LA Times, Floyd Mayweather's 5,200 square foot Miami Beach pad was completed in 2015 and was recently listed at over $8.49 million, but when you're paying in cash I guess you get a discount. 

So what does $7.7 milly get you in Miami Beach?

The mega mansion features floor to ceiling windows throughout, a glass and steel floating staircase, five bedrooms, five bathrooms, a chef's kitchen, a zero-edge swimming pool & spa, a roof deck, a private dock, Ipe privacy walls around the perimeter, and views of the Intracoastal Waterway. 

Why would Mayweather feel the need to get back in the ring ever again?
