While pre qualification may last up to 90 days for a mortgage, with a personal loan, the prequalification period may only last for a week or two. That being said, do not be rushed into a personal loan that you are uncomfortable with. A week or two weeks is a long enough period of time for you to shop around and see what different lenders have to offer. Using Acorn Finance helps since Acorn brings all the interested lenders together for you to easily view their various offers.
