I had listen to his mp3, Multiple Stream of Income and read few of his book. What I can say is good for education but not much we can do with our real life. He is focus on real estate investment with nothing down (without downpayment) but we do not have that opportunity here at Malaysia.
He had to search for 100 in order to get 1, to get one stupid seller who are welling to sell his/her property to you at 30% lower then market price.

The realistic view of the possibilities is zero. Good for entertaining and education, not for practical.
John T. Reed is writing details about him, plus a lot more market real-estate investment gurus.
