Alex Rodriguez reportedly just sold his Miami Beach mansion for $30 million, and it looks like it is worth every penny.  According to numerous sources, Alex had purchased the home for a mere $7.4 million in 2010.  I am definitely not a math major, but that seems like a decent return on investment.  The full listing is available on Sotheby’s, and you can take a tour of the digs below if you would like to see just how ridiculously nice the house is.
