Montana Title 32. Financial Institutions § 32-5-302. Installment and balloon payments

(1) Except as provided in subsection (4), if the loan contract requires installment payments, the contract must provide that principal and interest be payable at approximately equal periodic intervals, except that payment dates may be omitted to accommodate borrowers with seasonal incomes.

(2) An installment contracted for may not be substantially larger than any preceding installment. If a loan contract provides for monthly installment payments, the first installment must be payable at any time within 45 days of the date of the making of the loan.

(3) A licensee may not enter into any loan contract in which a borrower agrees to pay principal or interest in one lump sum unless the payment is due not less than 45 days from the date of the making of the loan and not more than 1 year from the date of the making of the loan.

(4) Loans with a balloon payment are permissible so long as all installment payments cover at least the interest that has accrued since the previous installment payment.
