CONSIDERING that the borrower wishes to borrow a fixed amount of money; and a person or business can use a credit agreement to set terms such as an amortization schedule with interest (if applicable) or the monthly payment of a loan. The most important aspect of a loan is that it can be adjusted to its liking by being very detailed or just a simple note. In any case, each credit agreement must be signed in writing by both parties. The borrower agrees that the money lent will be repaid later and possibly with interest to the lender. In return, the lender cannot change his or her mind and decide not to lend the money to the borrower, especially if the borrower relies on the lender`s promise and makes a purchase expecting him or her to receive money soon.
