Most programs target end to end syndication and charge a boat load. I would suspect that many students never put anything into meaningful action after the excitement from the seminars or coaching programs wane. It can also be overwhelming to many as its really a team sport when they are balancing full time jobs, families, etc. I'm sure there are a lot of programs that are fairly similar in nature. However, very, very few put you in practical, "think apprenticeship type" opportunities to learn alongside experts doing large, syndication deals enabling you to rapidly grow your experiences , knowledge and credibility in a safer environment (less bruises and broken bones) without damaging your pocket book and reputation doing bad deals in less than stellar markets.
I like what @John Casmon summarizes, do as much homework on yourself as you do on what the coach is offering to see if a match. Forget focusing on "who's the best"...that really is not the most effective way to go about it. Be more intelligent, introspective than that. If I ask the coach "how can I help you" is there a way, path to partner even if its a small role on the team. Do it for the experience and what you'll gain in your business as a result. Will the investors I bring to the deal be my investors? Will I grow my knowledge base across all areas of the business? Is this a person I can work with from a personality perspective who wants the best out of me and willing to give their time, energy and passion?
