  3. Twenty calendar days of bidding; extended if a bid arrives in the last hour.
  4. Award to the best bidder at the thresholds of LEC arts. 670–671 (70% of the auction value, with special rules below that); if no bidder, the creditor may take the property (art. 671) or assign the award (art. 647.3).
