Washington Installment Promissory Note Overview

An installment promissory note in Washington must comply with the state's usury limit of 12% and follow Washington'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.

Washington 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 15 days are observed before assessing late fees, and that acceleration clauses include proper notice requirements. Prepayment penalty status in Washington: Limited.
