(a) A community center may purchase or lease-purchase real and personal property and may construct buildings and facilities.
(b) The board of trustees shall require that an appraiser certified by the Texas Appraiser Licensing and Certification Board conduct an independent appraisal of real estate the community center intends to purchase. The board of trustees may waive this requirement if the purchase price is less than the value listed for the property by the local appraisal district and the property has been appraised by the local appraisal district within the preceding two years. A community center may not purchase or lease-purchase property for an amount that is greater than the property's appraised value unless:
(1) the purchase or lease-purchase of that property at that price is necessary;
(2) the board of trustees documents in the official minutes the reasons why the purchase or lease-purchase is necessary at that price; and
(3) a majority of the board approves the transaction.
(c) The board of trustees shall establish in accordance with relevant rules of each appropriate department competitive bidding procedures and practices for capital purchases and for purchases involving department funds or required local matching funds.
