He lived in SF area when the recession was hit hard in 1993 then 2007. He lost most of his giant money in the stock market. He gave his first house to his ex-wife (the house was valued at about $550,000 before 1993 recession). He owned $750,000 house in Walnut Creek before 2007 economic crash and he kept paying his monthly mortgage was more than the value of his house (it went down to about $400,000). It sank and he didn't want to lose more money to the mortgage so he left the house keys in the house and informed the bank that he walked away from it. Now you know that he lost most of his giant money to the stock crash, one to his ex and a foreclosure.
