Indiana Code Title 36. Local Government § 36-7-12-26

Sec. 26. (a) A financing agreement approved under this chapter must provide for payments in an amount sufficient to pay the principal of, premium (if any), and interest on the bonds authorized for and allocable to the financing of the facilities.  However, interest payments for the anticipated construction period, plus a period of not more than one (1) year, may be funded in the issue.

(b) The term of a financing agreement may not exceed forty (40) years from the date of any bonds issued under the financing agreement.  However, a financing agreement does not terminate after forty (40) years if a default under that agreement remains uncured, unless the termination is authorized by the terms of the financing agreement.

(c) If the unit retains an interest in the facilities, the financing agreement must require the user or the developer to pay all costs of maintenance, repair, taxes, assessments, insurance premiums, trustee's fees, and any other expenses relating to the facilities, so that the unit will not incur any expenses on account of the facilities other than those that are covered by the payments provided for in the financing agreement.
