New and Excited!!

[Jason Byrdsell]

Hello all, I'm excited about being here on Bigger Pockets... I'm excited about my beginnings in investing here in Atlanta.  I've owned a rental once before but decided that wasn't for me... At least not the way I was doing it.  I'm here to do some wholesaling and then right into longer term investing and commercial real estate to include markets outside of Georgia.  I'm currently looking at a pre-foreclosure property that seems like it should have some money left in it based on the information I have.  Logically, the numbers make sense but when I do the numbers I can't seem to make sense of it and I believe it has a lot to do with the comps (as there are few within the last 90 days and within a mile).  How reliable are Zillow's Zestimate and Foreclosure estimates?  Lastly, when a home is in Pre-foreclosure I am still just signing a contract with the owner, right?  I just so happen to be introducing myself at the same time I have this question so I may post this in one of the other forums as well.... 

Thanks a ton for any advice!
