Purchases — prohibitions

1. No sale or purchase of real estate shall be made save upon the order of the board, made at a regular meeting, or one called for that purpose, and then in such manner and under such terms as the board may prescribe. No member of the board or any of its committees, offices or agencies, nor any officer of any institution, shall be directly or indirectly interested in such purchase or sale. 2. Purchases of real estate may be made on written contracts providing for payment over a period of years but the obligations thereon shall not constitute a debt or charge against the state of Iowa nor against the funds of the board or the funds of the institution for which said purchases are made. Purchase payments may be made from appropriated capital funds or from other funds lawfully available for that purpose and allocated therefor by the board, or from any combination of the foregoing, but not from appropriated operating funds. All state appropriated capital funds used for any one purchase contract shall be taken entirely from a single capital appropriation and shall be set aside for that purpose. In event of default, the only remedy of the seller shall be against the property itself and the rents and profits thereof, and in no event shall any deficiency judgment be entered or enforced against the state of Iowa, the board, or the institution for which the purchase was made. Provided, however, that no part of the tuition fees shall be used in the purchase of such real estate.
