Any community college district may, as a part of its 25% contribution for building purposes, contribute real property situated within the geographical boundaries of such community college district at market value as determined at the time the contribution is made to the Capital Development Board in accordance with the program and budget, the plan as approved by the State Board by 3 licensed appraisers, except that where a community college district has acquired such lands without cost or for a consideration substantially less than the market value thereof at the time of acquisition, the amount of the community college district’s contribution for the land shall be limited (a) to the difference, if any, between the appraised market value at the time of acquisition and the appraised market value at the time the contribution is made to the Capital Development Board, if the grantor is the Federal government, (except that no property acquired prior to December 18, 1975 shall be affected by the provisions of this Section), or any department, agency, board or commission thereof or (b) to the actual amount, if any, of the consideration paid for the land if the grantor is the State of Illinois or any department, agency, board or commission thereof.
     In the event the highest appraisal exceeds the average of the other two appraisals by more than 10%, such appraisal shall not be considered in determining the market value of the land and a new appraiser shall be appointed by the State Board, who shall re-appraise the land. The re-appraisal shall then become the third appraisal as required by this Section. The cost of the appraisement shall be paid by the community college district.
