Idaho Installment Promissory Note Overview

An installment promissory note in Idaho must comply with the state's usury limit of 12% and follow Idaho's lending regulations. The note establishes a fixed payment schedule where the borrower repays the loan through regular installments of principal and interest over an agreed-upon period. Each payment follows an amortization schedule that shows exactly how much goes toward reducing the principal versus covering interest charges.

Idaho law provides specific protections for both lenders and borrowers in installment note transactions. The state requires that interest rates stay within the usury limit, that grace periods of 10 days are observed before assessing late fees, and that acceleration clauses include proper notice requirements. Prepayment penalty status in Idaho: Yes.
