Sheriffs Sale - Lien and Subordinated

[Nick Fegley]

BP Community, I appologize up front for asking this question, as I'm sure it has been answered somewhere on this site, however, I was not able to find a clear answer. 

Situation: Sheriff's Sale of properties I would like to bid on in two weeks.

My confussion: Some of the properties have a lien from the mortgage company, and some have subordinated liens in addition. 

My plan: Go to the courthouse the day before the auction to look at liens on property. 

My issue: I don't understand if the liens (including subordinate) will be whiped off the deed once I buy the property, or not. If not, does anyone have any experience or strategies on repaying the outstanding liens and getting a clear deed?

Thank you for any feedback you give.
