If you don’t qualify for a personal loan through Prosper, consider applying with a co-applicant. Applying with a co-applicant could improve your chances of getting an offer. Plus, it might lower your rate. Your co-applicant should be someone you trust with strong credit and a steady job. Our partner WebBank issues personal loans based on creditworthiness. Borrowers who accept a personal loan through Prosper must have a credit score of 640 or higher to qualify for a loan.
