The Forbes article seems to suggest that his wealth has been built on nothing but shady deals. In fact they go so far as to accuse him of building a new Countrywide Mortgage.

Using his brain...and aggressive and questionable business practices

You won’t find any libraries or schools or hospitals with his name on them. He hasn’t signed Warren Buffett’s Giving Pledge. And he’s anything but a patriot: In an effort to avoid taxes, he renounced his U.S. citizenship in 1999. You’ll find him on our list as a citizen of Ireland.

Since the Great Recession Grayken has made a specialty of buying up distressed and delinquent home mortgages from government agencies and banks worldwide. He’s also picked up a major payday lender, a Spanish home builder and an Irish hotel chain. Regulators hassle him, and the homeowners whose mortgages he owns or services despise his tactics. In fact, he has become accustomed to taking shots from detractors and has been the subject of protests from New York to Berlin to Seoul. Last year New York Attorney General Eric Schneiderman reportedly opened an investigation into Grayken’s heavy-handed mortgage-servicing tactics, including aggressive foreclosures, which have unleashed widespread outcries from homeowners, housing advocates and trade unions.

Sounds like a real saint
