The commissioner is authorized, in connection with any examination or audit of any association, to cause to be made appraisals of real estate owned or held by the association as security or otherwise when specific facts or information with respect to the real estate, or when in the commissioner's opinion the association's policies, practices, operating results, and trends, give evidence that an association's appraisals may be excessive, that lending or investment may be of a marginal nature, that appraisal policies and practices may not conform with generally accepted and established professional standards, or that real estate held by the association for any purpose is overvalued. In lieu of causing the appraisals to be made, the commissioner may accept any appraisal caused to be made by the federal home loan bank board, or by the federal savings and loan insurance corporation or other insuring agency approved by the commissioner under this chapter. Unless otherwise ordered by the commissioner, appraisal of real estate in connection with any examination or audit pursuant to this section shall be made by a professional appraiser or appraisers selected by the commissioner, and the cost of the appraisal shall be paid promptly by the association directly to the appraiser or appraisers upon receipt by the association of a statement of the cost bearing the written approval of the commissioner. A copy of the report of each appraisal caused to be made by the commissioner pursuant to this section shall be furnished to the association within a reasonable time, not to exceed sixty (60) days following the completion of the appraisals, and may be furnished to the insuring agency.
