Since your credit score is based on five factors (Payment History, Credit Utilization, Length of Credit History, Recent or New Credit, and Types of Credit or Diversification of Credit), there are some things you can do in the long term to improve your credit:
1. Obtain Your Free Credit Report once every 12 months. This will help you keep tabs on unusual items or accounts appearing on your report.
2. Manage Your Credit Card Balance. Try to keep the balance on each of your credit cards below 30% of your credit line. Also, don't close any unused credit cards because then you can keep a lower ratio of credit card debt to available credit.
3. Dispute Credit Card Errors. Credit bureaus need to be made aware of inaccurate information. You have the option to do this yourself or hire Kahlua Credit, a credit repair company, to contact the bureaus on your behalf.
4. Pay Bills on Time. Don't want until the due date, pay your bill the day it comes in if you can. Automatic online bill payments can save you the hassle of having to remember.
