(a) At any sale of real or personal property upon which there is a mortgage, pledge, or other lien, the holder thereof may become the purchaser and, unless the property is being sold subject to the lien, may apply the amount of his or her lien on the purchase price in the following manner:
(1) If no claim thereon has been filed or allowed, the court, at the hearing on the report of sale and for confirmation of the sale, may examine the validity and enforceability of the lien or charge and the amount due thereunder and secured thereby and may authorize the personal representative to accept the receipt of the purchaser for the amount due thereunder and secured thereby as payment pro tanto.
(2) If the mortgage, pledge, or other lien is a valid claim against the estate and has been allowed, the receipt of the purchaser for the amount due him or her from the proceeds of the sale is a payment pro tanto.
(b) Nothing permitted under the terms of this section shall be deemed to be an allowance of a claim based upon the mortgage, pledge, or other lien.
