Whenever acquiring property, the governmental unit may pay the purchase price in full or may exchange property with the seller as a trade-in and apply the exchange allowance to the cost of the property acquired. If, whenever acquiring property, the governmental unit may best serve the interests of the county or district by outright sale of the property to be replaced, rather than by exchange as a trade-in, it may make the sale in a manner otherwise prescribed in this act for the disposal of property. The receipts from the sale may be treated as a current refund if the property to be acquired shall be contracted for within the same fiscal year of the governmental unit in which the property sold is disposed of.
