Roger Federer & Mirka Federer – Wollerau, $8.5 Million

Some persons don’t realize it, but Mirka Federer once played tennis also. In 2002 an injury forced her to stop playing permanently. But though she’s not on the court any longer, she’s Roger’s PR manager and she is doing a great job at it, too. Mika and Roger have four children together—twin boys and twin girls. The family lived in a glass mansion with floor to ceiling glass windows called The Residence and it was a major investment. Federer moved into it a year before he married Mirka, but it was recently sold.
