This is a great Q. I've seen quite a few gurus out there, some great, some not... I think @Charles Carillo said it very well above.
I'd point out that coaching is only as good as your focus on the path, and the action you will take from it.
(I've seen many people pay for coaching to feel like they're 'doing something' and 'taking massive action' when in reality, they're kind of just delaying taking action, and like to talk about how they're in XYZ program.)
I've also seen people jump into coaching programs, and take direct and coached action, and skyrocket in their careers.
I think that the successful coaching students will take any coaching, and apply the knowledge and networking, and DO something, like go buy a property.
That being said, if you're looking at coaching programs, I'd suggest:
1. find a coach/mentor/guru that is personally where you want to be in X years. They are your literal goal, not just 'an idea.' "Coach JOE has 10,000 doors under management in a syndication model. They personally cash flow $XYZ per year. THAT is exactly what I want." or "Coach JANE personally owns 300 doors to their name, no investors, and cash flows $XYZ per year. THAT is exactly what I want."
2. Once you find that person, I'd personally suggest going after them wholeheartedly, and once you're on board, stop listening to other gurus/experts on social media/blogs/etc. They will simply cloud the path you have clearly chosen. (If you are being coached by one guru who is teaching you how to own your own doors using hard money, but also listening to a syndicator who partially owns their doors and brings on investors and promotes that model, those are different game plans/paths and will only cloud your focus).
3. If you are assessing if this person is the real deal, ask the hard questions until you feel you have a good answer. This is tough, because the sales process will make you feel rushed, or like you're wasting their time when they are in such high demand, that you are LUCKY to get into their $XYZ program... This should be a life-long path you're going down, so stick to your guns until you're satisfied.
4. don't be woo'd or glamorized by flashy sales techniques. Real estate is boring, and not always cute, why should the coaching be?
5. be aware if you're being coached by the guru themselves, or a coach 'below them.' If being coached by someone below them, THAT is who you should really be sussing out. I've seen gurus hire coaches with very little experience. Then people pay the guru based on the sales tactics, but the coach they're getting is definitely NOT worth (any) money, in my opinion.
6. Once you sign up, and fork over any time and money, please please commit to take action on your coaching, preferably as you go. Don't wait to 'know it all' from the coach before you start working. Most processes have action steps along the way, you'd be well off to just get moving in this game. The next steps will present themselves, and your coach should be able to hold your hand and guide you as you progress.
Hope that helps! Feel free to ask any Questions.
