What is the payoff for a lien that went to sheriff sale in MN?

[Kerry W.]

I am wondering what will happen to a condo in MN that is owned free and clear except for an association lien. The lien is for $6000 and went to sheriff sale and bid at $41,000. The owner wants to pay off the lien before the end of the redemption period and wants to know if she has to pay off $6000 (this bid was given to us days before the auction from the association's attorney) or the $41,000? I buy liens and notes but not sure from a homeowners perspective what their payoff would be? Any help is greatly appreciated.
