La. Code Civ. Proc. art. 2336
Except as provided in Article 2332, the property shall not be sold if the price bid by the highest bidder is less than two-thirds of the appraised value. In that event, the sheriff shall re-advertise the sale of the property in the same manner as for an original sale, and the same delay must elapse. At the second offering, the property shall be sold for cash for whatever it will bring, except as provided in Article 2337. The debt owed to the seizing creditor shall not be reduced by the costs of the sale, but shall be reduced by the greater of either one-half of the appraised value, less superior security interests, mortgages, liens, and privileges, or the amount by which the price bid exceeds superior security interests, mortgages, liens, and privileges.
