Pre - Foreclosure Approach

[Maria Mastej]

I am in currently in the early stages of rehabbing my first rental property, and through a little research, I see that the adjacent house is 2 years delinquent on their taxes.  

I know pre - foreclosure is not the prettiest way to go about purchasing property, however, this seems like an ideal situation to have my first and second rental properties adjacent to each other.  Are there any books out there for how to best approach this conversation, or this situation in general?  Has anyone out there acquired property this way that can advise?

Thanks!
