I would not waste my time reading Dean Graziosi's book. I would also warn anyone who wants to sign up for his coaching program, PMI/Dean Graziosi Real estate success academy, that it is a scam and they will NOT refund your money. The course is redundant and a waste of money. There are too many great sites online for people interested in real estate investing and it's free! Dean's students only get their money back by misguiding you, beware. Google Dean Graziosi scams, there are thousands of complaints. Buyers Beware! The Attorney General in Utah and Arizona are aware of Dean's Enterprises and the many different names his companies are under. I have been burned out of $12,740 that they refused to refund me after 2 weeks. Turns out, many people have similar stories. Dean Graziosi is a scam artist and a crook.
Dean Graziosi's books and training programs are not scams. If you read the books and didn't understand the material, then purchased a program or personal training, and it still didn't work for you, then you should be honest to say just that - it didn't work for YOU. Not every student who pays for a college education graduates to become a success story, for whatever reason. Check yourself rather than trash a good guy's work. You probably simply work for his competition. Shame on you, and soup at you.
