45-21.9. Amount to be sold when property sold in parts; sale of remainder if necessary.

(a) When a person exercising a power of sale sells property in parts pursuant to G.S. 45-21.8 he shall sell as many of such separately described units and parcels as in his judgment seems necessary to satisfy the obligation secured by the instrument pursuant to which the sale is being made, and the costs and expenses of the sale.

(b) If the proceeds of a sale of only a part of the property are insufficient to satisfy the obligation secured by the instrument pursuant to which the sale is made and the costs and expenses of the sale, the person authorized to exercise the power of sale may readvertise the unsold property and may sell as many additional units or parcels thereof as in his judgment seems necessary to satisfy the remainder of the secured obligation and the costs and expenses of the sale. As to any such sale, it shall not be necessary to comply with the provisions of G.S. 45-21.16 but the requirements of G.S. 45-21.17 relating to notices of sale shall be complied with.

(c) When the entire obligation has been satisfied by a sale of only a part of the property with respect to which a power of sale exists, the lien on the part of the property not so sold is discharged.

(d) The fact that more property is sold than is necessary to satisfy the obligation secured by the instrument pursuant to which the power of sale is exercised does not affect the validity of the title of any purchaser of property at any such sale.
