Information on vetting for foreclosure properties

[Chan M Stagg]

I have been a active home flipper for many years now, but have always been scared to delve much into buying foreclosure properties on the courthouse auctions. Biggest roadblock for me is being able to figure out the best way to vet these properties to make sure there is no hidden liens or anything that would kick my butt after a purchase. I have someone who works at a title agency that say she would help me in a title search but I feel like she would just be doing a casual search because I'm not getting title insurance or anything like that with this search. I've heard a few stories of people getting screwed in these foreclosure properties because they didn't do the research.  Anyone know any sources of information I could get on this subject?
