Personal loans can be declined for many reasons, but in most cases it’s due to a poor credit score or unreliable credit history. Before reapplying, take a look at your credit report (you’re allowed one free report per year from Equifax, Transunion, and Experian). If your score is less than good (660 or less), try taking some time to improve it. If you see any errors on the report, dispute them immediately with the three major credit bureaus.
