Bird Dogging for Beginners?

[Ryan Dao]

Hey, I was wondering how does one get started bird dogging? Is there a process on how to do it? Is it just looking at vacant/boarded up properties and seeing which look good? Also is it a good way to start off your real estate investing career? 

I know that you might need a licence to officially legally establish yourself as a bird dogger or something like that; I'm not really too sure. In addition, I'm 17, so I'm still a minor, does that affect anything in the process involved? I know that I can't wholesale for that reason.
