What's the best way to "test the waters" with CRE?
I'm semi-retired. Basically, I have 6 apts and live a simple/frugal life. I also own 3 vending machines. 

I find CRE alluring...lots of excel (I love excel) and lots of networking (I love networking). I also enjoy reading real estate books for the pure joy. I want to explore it.

What would you recommend doing? Start taking CCIM classes? I'm based in Boston btw.

Thx!
