The borrower can take money out as needed until the limit is reached, and as money is repaid, it can be borrowed again in the case of an open line of credit.
The member can access funds from the line of credit at any time if they do not exceed the maximum amount (credit limit). Money can be borrowed as needed, paid back and borrowed again.
A line of credit works much like a credit card account except without a plastic card. The interest rate for a LOC is also less then a typical credit card.
It is great to use as an emergency expense tool.
