Query: Unbelievable returns

I first heard Joel Cassaway over ten years ago in Orlando when he was a lecturer and investment trainer for a popular real estate seminar company. Joel packs a lot of information, is fun to listen to too and a excellent trainer.Joel discussed discounted mortgages. I followed his advice and netted a 150% return!What more can I say? This guy knows his stuff.
