When it comes to applying for a short-term loan, there’s the option of either going with a direct lender or a broker. The critical difference between the two is that a direct lender provides the loan directly to you, while a broker will search around various lenders.

At Uncle Buck, we are a direct lender, which means when you apply for a loan with us, you borrow straight from us. Our lender status ensures that you always know exactly who to turn to should you have any questions, and your details won’t be passed on to any other lenders without your permission.
