If you have a low credit score, you will not be able to get a loan. Therefore, you should make sure to have sound, personal finances. Pay back your existing loans; this will give you a better payment history. Keep a low debt ratio. This means that your total debt to income ratio is low. Your debt ratio is something that banks are always looking at when they evaluate potential loan clients. Also make sure that your application is correctly and completely filled out. If there is important information missing in the loan application, it will most likely be rejected.
