Glad you asked...
To write a loan agreement, you will want to make sure that you put in how much you are borrowing, the amount of payments you are going to make, and if you are going to make them on a monthly or weekly basis. You will want to put a time when the loan should be paid off.
Then again, this answer might help you...
To write a load agreement, you need to outline all details of the loan. Include all information regarding the the loan, the amount of the loan, interest, fees and any extra charges and include the totals of the repayment. Then also include the information on what could happen if the loan is paid late or not repaid. Always include information that protects both sides of the loan.
