If so, is it as a lien against the property under contract?

They were insuring that the property was free and clear of all liens and encumbrances.

I'm looking to gain experience in wholesaling and tax liens short term, and look into fix and flips as well as rentals long term.

Yes, if this is an upset sale, then you will be responsible for all the liens associated with the property.

Typically which liens stay with the property after the foreclosure? 

5) Are there other liens against the property?

If these lenders are family, they will probably not push the title issue and require a lien.
