Knocking on doors of foreclosure homes

[Ben Boru]

Okay so I am an amateur and this will sound amateurish. I'm looking to buy a home to flip in Michigan. Piece of crap preferably. (There is a 6 month redemption period). I am a contractor and can do alot of the work myself with my wife. Anyway can I just approach a homeowner of a house up for auction and gain their trust and work out a deal with them directly? Any advice before I start trying would be greatly appreciated.
