When a lien is foreclosed in accordance with RCW 60.11.060, the disposition transfers to a purchaser for value all of the lien debtor's right therein and discharges the lien under which it is made and any security interest or lien subordinate thereto. The purchaser takes free of all such rights and interest even though the lienholder fails to comply with the requirements of this chapter or of any judicial proceedings under RCW 60.11.070:

(1) In the case of a public sale, if the purchaser has no knowledge of any defects in the sale and if he or she does not buy in collusion with the lienholder, other bidders, or the person conducting the sale; or

(2) In any other case, if the purchaser acts in good faith.
