So, I'm considering real estate as a side gig until one day it surpass my current full time job income.

:D Don't have any as of yet, but reviewing currently what others are doing then will select some on my own.Social media is a big one, don't understand it as of yet, all I know it is a free powerful medium, facebook has either surpassed or equaling the traffic numbers google has making it a formidable enemy to google in terms of advertising dollars...google is nervous of facebook.Note:Social media is a must for me, so it will be one of my favorites, it's just I don't understand how it works just yet !

It's great that you are putting together these systems. 10 units, you are surpassing me!

The climate, the variety of attractions and things to do surpass almost any other place. 

I am very fortunate that I have had the opportunity to invest in over a dozen properties in the Phoenix market that have been able to sustain very high (over 20% annual cash on cash returns), as well as add value to many properties and seen some properties surpass 50-65% appreciation.

For example, Ontario is a growing area, likely to surpass Los Angeles in near future growth because of the availability of space, an international airport, and the crossroads of major freeway corridors.
