@Bob Prisco Most of the people on this site, as you can tell by many post, are not investors in any capacity so there's a very steep learning curve to get past before they are comfortable investing for the first time.
I think they use the Guru's to try to speed up that path to investment launch, same with the books. Warren Buffet, and many other billionaire investors all say, you will have to "Do the time" to understand your investment vehicles to be successful, there is no way around it.
Learning curves will vary, but those seeking true success will need to account for time and experience. I'm not talking about those post on here where the first time investor is posting about getting 50 doors in 90 days, almost always they will not tell you those doors are producing a net income of $30 a month, that's not an investment, that's a gamble where the "investor" is hoping for a favorable scenario when the Debt gets restructured at the end of the 7, or 10 year term, and then hoping the rent increase projections happened, hoping the vacancy turnover projections they forgot to account for don't come to fruition (you'll be amazed at how many people will have a 5% vacancy reserve, but they forget about the Unit turnover cost), Some get lucky swinging for the fences out the gate, many do not.
I think there may be some hesitance to doing deals for new investors because they see these post on the site, then they look at the industry, and see the reality of the complexities involved in REI.
I always tell people, that person you see selling their distressed property, the investment Foreclosure, the deep discount at sale, etc.. were all deals investors did their analysis on but the deal failed.
Lastly, I think it's the money, most new investors are spending their lifesavings on this initial investment, the fear of wiping-out is real.
