Line of Credit
Collateral is something you pledge as security for repayment of a loan, such as your car or home.
Both of these loans are available without collateral. A signature loan is offered as a lump sum, whereas a line of credit is a source of funds that you can draw from whenever you choose. With a line of credit, the money that is repaid becomes available again. There are advantages to both, depending upon your needs and circumstances. A signature loans gives you more cash up front, whereas a line of credit is more flexible.
