Alabama Code Title 11. Counties and Municipal Corporations § 11-54-3

Each municipality shall have the power to sell to any person all or any part of any land held by it as the site of an industrial park;  provided, however, that no such sale may be made for less than the total amounts expended by the municipality with respect to the property so sold or for less than the reasonable market value of the property so sold as such value shall be established by appraisals of at least two independent appraisers.

Prior to making any sale of any property comprising all or part of an industrial park, the municipality making such sale shall cause appraisals of the market value of the property to be so sold to be made by at least two independent appraisers and shall cause a copy of each such appraisal to be filed in the permanent records of the municipality. Each such appraisal shall be dated not earlier than 60 days prior to the consummation of any such sale. In any case where each appraisal obtained pursuant to the provisions of this section sets forth a different value, the average of the market value stated in the separate appraisals shall be deemed to constitute the reasonable market value of property for the purposes of this section.
