A Loan Repayment Agreement Letter is a document outlining the terms and conditions for repaying a loan. The letter should include details such as loan amount, interest rate, payment schedule, term of repayment, late fee policy and any other relevant information. It should also state that the borrower is responsible for understanding the full terms and conditions of the agreement and will be held accountable for adhering to them. This important document sets out the expectations for both lender and borrower to follow in order for successful repayment of a loan.
