loan

Written or oral agreement for a temporary transfer of a property (usually cash) from its owner (the lender) to a borrower who promises to return it according to the terms of the agreement, usually with interest for its use. If the loan is repayable on the demand of the lender, it is called a demand loan. If repayable in equal monthly payments, it is an installment loan. If repayable in lump sum on the loan's maturity (expiration) date, it is a time loan. Banks further classify their loans into other categories such as consumer, commercial, and industrial loans, construction and mortgage loans, and secured and unsecured loans. A written promise to repay the loan is called a promissory note.
