Sec. 6. (a) Subject to section 6.5 of this chapter, the executive and legislative body, on behalf of the township, may also borrow the necessary money from a financial institution in Indiana to make the purchase on the same terms. They shall, on behalf of the township, execute and deliver to the institution the negotiable note or bond of the township for the sum borrowed. The note or bond must bear interest, with both principal and interest payable in equal or approximately equal installments on January 1 and July 1 each year over a period not exceeding six (6) years.
(b) The first installment of principal and interest on a contract, chattel mortgage, note, or bond is due on the next January 1 or July 1 following the first tax collection for which it is possible for the township to levy a tax. The executive and legislative body shall appropriate and levy a tax each year sufficient to pay the obligation according to its terms. An obligation of the township executed under this chapter is a valid and binding obligation of the township, notwithstanding any tax limitation, debt limitation, bonding, borrowing, or other statute to the contrary.
