A Loan Agreement with Guarantor and Security is a comprehensive contract that outlines the terms and conditions of a loan, involving three key parties: the lender, the borrower, and the guarantor. The agreement specifies the loan amount, interest rate, repayment schedule, and any penalties for late payments. The guarantor, often a third party, agrees to take responsibility for the loan if the borrower defaults, providing an additional layer of security for the lender.
