The one thing i will agree with in John Webster's post is that everyone is different and most people who sign up probably never do a deal. I am not familiar with his market, but i would be cautious about thinking it's easy. Although i have not attended any of their events in a couple of years, i have never heard them say that they will bring you deals or money. That has definitely never been our case nor the case of the other students we know. You might want to PM John to find out what he's talking about, but please don't join thinking that deals and/or money will be brought to you.
I always tell people that they have to do some self reflection. If you are self-motivated and have found success in other areas of life, you probably have a good chance of finding some level of success with FB. If you haven't done so already, i would go to some local REIAs and get an understanding of your market conditions before making a decision. There are quite a few people who joined around the same time we did a few years ago who are only breaking even (or losing money) on flips because deals are so hard to find in our area and they are buying at elevated prices.
