12. Derek Jeter
You know your house is legendary when it has its own nickname. Derek Jeter’s mansion in St. Petersburg (Florida) is so massive that neighbors refer to the home as “St. Jetersburg.” Construction of Jeter’s 30,875-square foot castle began in 2009. According to Zillow, the home features 7 bedrooms, 9 bathrooms and is roughly the size of a BestBuy electronics store. If that’s not impressive enough, his backyard is right on the water and sports a gorgeous swimming pool and private dock. Not a bad place to retire after 20 seasons in the Majors.
