I think I know who this joker is...
infamous Vietnamese immigrant busboy turned real estate seminar scam artist of the 80's.
Well, if it's that guy the site I checked out says he's in jail. His secret? No money down. His other secret? He's the only one who made money from his books and seminars, so while he got rich quick, no one else did. If it's not that actual guy, sure sounds like someone similar.
