There is a rebuttable presumption that any property within a district acquired or leased as lessee by a municipality, or any agency or instrumentality of the municipality, within one year immediately preceding the date of the creation of the district was acquired or leased in contemplation of the creation of the district. The presumption may be rebutted by the municipality with proof that the real property was leased or acquired primarily for a purpose other than to reduce the tax increment base. If the presumption is not rebutted, for purposes of determining the tax increment base of the district, the taxable status of the real property is determined as though the lease or acquisition had not occurred.
