Best I can tell, we have a good supply of majors in law, anthropology, fashion, photography, theater, philosophy, psychology, history and sociology. 

I effectively own two houses inside of the HELOC, which supercharges my cash flow on them, because I only have one "payment" between the two, and that payment can be interest only if times are tough.I also am riding a sixteen-month interest free balance of 11k on a Capital One credit card, which is a personal line of credit.

That's the guy who's going to take you for a ride!

Then stick with that strategy and do not deviate (shiny object syndrome) until you have mastered it or are fully ready to say 'this isn't the one for me'.The biggest benefit of creating a plan for yourself and beginning with the end in mind is that doing so will help you avoid buying yourself another job or getting taken for a ride by a Nuru (new guru, term courtesy of @Paul Moore).

I suggest trying to be the little guy who rides there coat tail, pay attention to what they are doing, where, how, and just play into the edges around that. 

you wont be performing activities in the same fashion as a realtor. 

With the potential of Oil prices on the rise I wanted to be able to capitalize off this in some form or fashion.

That could mean traveling the world, running a vacation rental, opening a restaurant, or starting a fashion design agency.

There is no way to assign these accounts to the tenants directly so -the water and sewer will remain in our name - Any advice on how to appropriately charge back to the two tenants in a equitable fashion?

You need to pay it off the old fashion way, which is reducing spending and temporarily sacrifice lifestyle.
