I think one of the important transitions from a typical consumer mentality is to being an investor or business owner it to understand the difference between "spending" money, and "investing" in your business.  

The challenge, as with most wealth building paths in life, is it takes not only knowledge but significant mental and emotional adjustment.

I'm looking at purchasing and renting a property to a not-for-profit agency that works with chronically homeless and mentally disabled people. 

If your target market are students, this may be a good option.. but you do need to be affiliated with that college/university (student, staff, alum, faculty, etc) to post on those groups.  

Why pay an extra fee or point when you can do it yourself, is my mentality.

I will initially look at purchasing positive cash flow property with a buy and hold mentality.

Also does he have a mental health history?

It's in the mental stages I would say!  

Starting out like you, Christopher, I think you have less mental pressure at USPS. 

I share the same mentality with respect to investing in RE - slow and steady.
