Should I take a house that was offered for free?

[Antonio Boone]

Hello BP, 

I have a coworker who wants to give me one of his houses for free. 

I have only taken a look at the house on google maps and from those images it looks like the house is going to take a lot of work. 

So I am not sure if it's a good deal? Or more specifically a good deal for me. 

The house fits a lot of my criteria. A duplex in the city I work in near a good school. However I not sure where to start to analyze the deal to see if it will work for me? I am also not even sure what questions to ask to get me pointed in the right direction.  With that said any advise is much appreciated. Any info i can provide let me know. Thanks!
