How a sherifs sale auction works

[Jered Sturm]

I have attend several sherif sale auction at the Hamilton county  court house in Cincinnati Ohio. I am very interested in beginning to purchase Fix and flip homes here. My only issue is there is very little info on how the whole thing works, and everyone down there that bids successfully I have asked to discuss it with me does not want to share information with me. 

Any insight on sherif sales would be much appreciated:

I understand the risk of having to buy them with out seeing the inside, possibly evicting the tenant, having an unclean title. My question what do you check for these things? Do you really have a title company run a title search on the property of interest only to then have it withdrawn from sale last minute? Do you check the recorders office to see what the bank is owed? How do other BPs buy at sherifs auctions?
