Hey Cody, I actually took the Rich Dad program in Canada. I split the $30k with a friend. Here's what I can tell you:
First, yes, it is a big chunk of change, but because real estate is so expensive where I live, I thought it better to spend $15k now than $15k + later for trial and error mistakes. Second, it is difficult to put a price tag on it; I made a few close friendships and good contacts by being in the community and they have helped me to invest. Third, it got me committed to making real estate my career path, but with the advantage of starting with a different, Rich Dad mindset. Fourth, I learned a ton about different strategies.
I bought my first property almost a year after and when I sell next spring, I expect to make my $15k back in addition to a healthy return.
Would I advocate it? In short, there is no substitute for experience. I'm pretty confident that had I not taken that course, I wouldn't have gotten into my first investment so soon. However the coaching and mentoring only goes so far. I'm sure that all the strategies I learned can be gained from books or listening to Bigger Pockets. Surrounding yourself with people who are actually doing what you want to do, finding mentors that want to help you for free and, yes, plain old trial and error are perhaps the most practical way to go.
Probably the best thing for someone with $15k, is to buy a ton of books and cds related to business, success & real estate, some quality business cards, one nice suit and gasoline to drive to events. Save the rest for a down or portion of a down. Oh and save a bit for a nice vacation!
Hope that helps!
