The trustees of any district may lease buildings or land suitable for school purposes when it is within the best interests of the district to lease the buildings or land from the county, municipality, another district, or any person. The term of the lease may not exceed 15 years unless prior approval of the qualified electors of the district is obtained in the manner prescribed by law for school elections, in which case the lease may be for a term approved by the qualified electors, but not exceeding 99 years. Whenever the lease is for a period of time that is longer than the current school fiscal year, the lease requirements for the succeeding school fiscal years shall be an obligation of the final budgets for such years.
