A loan that allows revolving use of the credit; that is, after funds have been borrowed and repaid they may be borrowed again without applying for a new loan. Typically, a credit limit is established and some or all of the available funds can be optionally disbursed at closing. Undisbursed funds are available for the borrowers use at any time. Payments are required only on the outstanding balance. They are similar in use to a credit card except that they typically use checks to access the funds.
