The board of county commissioners may by resolution engage licensed real estate brokers to attempt to sell property not sold at the annual November sale. The resolution must authorize sale by way of nonexclusive listing agreements; describe the real property to be sold; provide a maximum rate of fee, compensation, or commission; and provide that the county reserves the right to reject any and all offers determined to be insufficient. Property that is subject to a special assessment lien for improvements made by a city must first be offered for sale to the city.
