All sales of property upon execution shall be made at auction between nine o'clock in the morning and four o'clock in the afternoon. After sufficient property has been sold to satisfy the execution, no more may be sold. Neither the officer holding the execution nor a deputy may become a purchaser or be interested in a purchase at the sale. When the sale is of personal property capable of manual delivery, it shall be within view of those who attend the sale unless the court directs the sale to be at some other place. The property shall be sold in parcels that are likely to bring the highest price. When the sale is of real property consisting of several known lots or parcels, they shall be sold separately or otherwise, as is likely to bring the highest price. When a portion of real property is claimed by a third person, that person may require it to be sold separately.
