Liens on a property and determining position

[Doug Kirk]

I have seen a few auctions on properties that have seemed to be something worth looking into but I am still learning how to locate all liens on a property or the position of those liens.   What do people use to do so, especially anyone on Central Ohio?  I have tried local governments sites with little luck.  I have also read a few auction foreclosure books as well.  Are there some of the data aggregation sites such at Deal Machine or Prop Stream that have this? I know there is risk to you never know what you are going to get. Just looking to know in the few cases I was considering bidding.
