Newbie - where to start researching deals

[Adam Bradley]

I am brand new to REI and should be ready to move on a first property, a multifamily rental property, in a couple of months. I would like to start researching what deals are available in my area, Birmingham Alabama area, so that I can get a general idea of numbers.

 For duplexes, triplexes, and smaller apartment complexes should I just be looking on Zillow and Trulia and the like or are there certain sources specific to my area where I can see deals before they go on the market.  I'm assuming that if I format my numbers according to those deals before they hit the market then I will have a better target price range for getting deals in the future. 

 Thank you very much for any input.
