Where buildings and improvements situated on tax-forfeited lands have been removed or destroyed by fire, windstorm, or flood, the Secretary of State may, in his discretion, sell the tax-forfeited lands for any amount he may deem reasonable, irrespective of the amount of taxes for which the property was sold to the state. The Secretary of State, in determining the sales price for the land, may take into account the cost of cleanup and removal of debris from destroyed buildings and improvements situated thereon, or may contract with the purchaser for cleanup and removal of debris from destroyed buildings as part of the consideration for sale of the land.
