The demographics of these investors are typically high income earners, almost 90% working in tech (software engineering, tech sales, computer science, etc).

I am currently a middle school science teacher, and although I find it to be extremely worthwhile and I get much value out of it, I know that I do not want to be teaching for the remainder of my working years. 

First, a lot of people exploit old people (some registered nurses, members of heavily regulated profession, with multiple degrees and licenses in nursing and medical sciences come to mind.

Laws vary by state and there are several ways to purchase Mobile Home Parks.Also, there is a formula but analysing each Park is more of an art than a science.  

It's not rocket science. 

This isn't rocket science, it's rather basic stuff. 

You probably don't really need a mentor, for a few apartments, it's not rocket science, I'm feeling it's reluctance and looking on the other side of the hill at what you believe might be greener pastures, they may not be as green as you think.I got bored easily too, I'd find some niche, get that down, get bored and move on to a different aspect, just because it was more fun.

This is not an exact science.

For example, we've got our systems down to a science now where I know it'll cost us $35/sq ft for cosmetic repairs (this will definitely vary depending on location/materials/your crew, so don't use our specific numbers), then if we can tell the house will also need bigger fixes such as roof, windows, mechanical, electrical etc. we add that in as well and we can use that to work the numbers backwards to get to our offer price.

I will graduate in May with no debt, a Computer Science degree, and a ~$70k/yr offer from a company I worked for as a school-required internship.
