If a property, which an entity other than the municipality has purchased or taken assignment from the municipality of a tax sale certificate, is placed on the abandoned property list, the property shall be removed from the list if the owner of the certificate pays all municipal taxes and liens due on the property within 30 days after the property is placed on the list; provided, however, that if the owner of the certificate fails to initiate foreclosure proceedings within six months after the property was first placed on the list, the property shall be restored to the abandoned property list.
