I guess I'll have to agree with Doug Leedy, J Scott.
As an "insider" - affiliate, student, community volunteer - let me express my take on the Renatus experience...
In the first place, it's not a "guru academy". While it's true that the instructors are experienced, successful investors - the founder requires that instructors make $1 Million using the method they teach before qualifying them as instructors, the instructors - with at least one noteworthy exception - are not teachers. One from Illinois - who is reputed to own roughly 3% of the rental properties in Danville, IL - was a high school teacher before taking up REI full time. Another of the instructors is one of only 200 known note investors of a certain calibre.
Unlike the "gurus", Renatus establishes communities around the country. They are roughly parallel to REIAs, without the NREIA association. We gather weekly. In our specific group, we hold study groups to discuss the classes and even implement what we learn. The fix-and-flip study group actively invests and raises private money during the study group session. There is also a buy-and-hold study group and another for the Essentials.
The "gurus" hold classes out-of-town. You have to travel, pay lodgings and attend classes, then you come home and you're back on your own to network and find support.
Renatus classes are on-line, 24x7. Classes are re-recorded as updates are needed, and there is no additional charge to access the updates. The community is there to support you.
The Essentials classes are available for one year. The AIT classes, if you get the $20K package (Essentials + AIT), are available to you from that point forward if fully paid, "for life" - meaning for the life of Renatus - including any / all updates and additions they choose to offer.
The communities also offer two workshops a month (most of them): a real estate workshop and a marketing workshop called "Super Saturday".
If you'd like to learn more, you may want to get on Scott Rowe's webinars and experience him first hand. He is the most active trainer in the nation doing two and three webinars a day for his teams. Scott is not the founder of Renatus, but is one of the three Founder's Advisory Board members who co-own the office where suburban Chicago community meets.
I can hook you up with those webinars, if you like.
If you REALLY want to compare success rates, try this: the "gurus" "boast" a success rate below 15%, blaming their lack-lustre performance on the students' failure to follow-through. Our suburban Chicago community, on the other hand, has outgrown it's facility, we must use the patio area of the Fuddruckers Hamburger restaurant across the street from our office to accommodate the fix-and-flip study group. Essentials is the biggest study group, then fix-and-flip, then buy-and-hold. Current unqualified estimates of our size are somewhere around 300 members. I'm not sure what that says about success rate, but success overall looks pretty good to me.
I guess if there's any "entrance exam" it's your own response to the initial presentation of the education as a gateway to your own REI business and as a marketing opportunity for those who choose to pursue it as such. Entrepreneurship - much less REI - is not for everyone, and those not entrepreneurially inclined will dismiss any such presentation, regardless of the business being presented. I recently wrote to someone in another thread that concern over how to afford it can be taken as a gauge of a person's readiness or suitability to take on an entrepreneurial endeavor.
Y'know, I have peripheral neuropathy, and it's REALLY hard to type some of those long words without messing 'em up!
So, that's my "last word".
One a personal note, my own preference is to approach new endeavors with as much education as I can reasonably acquire. This takes away most of the "fear factor", since fear is typically born of lack of knowledge. No school can teach you to invest successfully any more than school can make you a successful entrepreneur. Success is something you must "bring to the table": it's intrinsic, you don't acquire success from external sources.
