Iowa Code § 633.396: Order for sale, mortgage, pledge, exchange or lease of real property.

The order shall describe the property to be sold, mortgaged, pledged, exchanged or leased, and may designate the sequence in which the several parcels shall be sold, mortgaged, pledged, exchanged or leased. An order for sale may direct whether the property shall be sold at private sale or public auction, and, if the latter, the place or places of sale. The order of sale may prescribe the terms, conditions and manner of sale. The court may, in its discretion, provide for appraisal for its guidance as to value of the property, and determine whether or not additional bond shall be deposited by the personal representative. If real property is to be mortgaged, it may fix the maximum amount of principal, the earliest and latest dates of maturity, and the purposes for which the proceeds shall be used. An order for sale, mortgage, pledge, exchange or lease shall remain in force until terminated by the court.
