Who says you can't make money in the music business? Iron Maiden have been hustling for over 30 years, and they are one of the biggest (and richest) bands not just in metal, but in all of music.
Case in point: Steve Harris, the bassist and creative force behind Iron Maiden is unloading his country house. It can be yours for a cool £6,750,000 (approximately $10,805,000 USD). Seriously, this place is ridiculous. Take a look:
I don't really understand the difference between a "country house" and a "mansion" because this looks as lavish as they come. According to the real estate listing, parts of the house date back to 1427. There is a pool, a recording studio, a bar AND soccer/tennis fields. This house has everything. AND IT'S PROBABLY WAS NOT EVEN HIS MAIN HOUSE!
That is rock star rich! If you're really interested, here's a PDF with more info about the house.
