I've got experience in the real estate industry in the capacity of home inspecting and radon inspecting, but I know that a career in sales would be much more beneficial towards actually doing deals.

Since septic systems are rated by bedrooms, there should be no capacity issue that you would run into.  

Sellers do not want to go through the time, effort and exposure, or tie up their property, in a transaction that has no chance to close.There are those extremely rare cases, that become real estate legend, in which a buyer with little capital, and no borrowing capacity, is successful in convincing a seller of a large, expensive property to take him seriously and is able to perform a high wire act of raising capital from a variety of unconventional sources and actually complete the purchase.  

I'm interested in popularizing this topic and starting a network of interested parties in any capacity. 

The question is how much do you make and could that result in significant contributions to such a plan.If you are just starting out, and have minimal contribution capacity and/or limited resources to rollover from prior retirement plans, then a self-directed Solo 401k is probably not going to benefit you.  

I would be grateful for any advice or direction you all could give me to achieve my goal of working in real estate in some capacity.  

Not sure at this point to what capacity I am going to use it, regardless though, the education and information within the course has been very valuable.

and how is your credit.if you have a little bit of money IE the 3.5% it takes to get a FHA loan then just go that route you need a job and credit as well.if you cant qualify for a FHA loan there  are not going to be any private lenders going to do anything with you in any capacity... remember those books are just ideas and maybe someone gets lucky but its not the norm by any means.. they are selling dreams..

To state the obvious, it's not like in Australia where you can approach almost any bank with a good borrowing capacity and a small deposit and buy a property almost anywhere in Australia.

@Rick - I pulled the data from the probate office and it appropriately references the executor's capacity.
