A credit product known as a revolver loan supplies continuous access to borrowed funds. Borrowers with this sort of loan are able to access their funds on an as-needed basis, and the collateral is usually real estate or inventories. Revolver loans are different from other loan types in that they are repaid on an as-needed basis, rather than according to a predetermined schedule. Since a company's day-to-day operations need a consistent infusion of cash, this type of loan is a lifesaver.
