The only thing that is going to make your credit better is time.
While we don't know exactly how a credit score is determined, FICO considers the following factors (the approximate weight it assigns to each factor is in parentheses):
· Payment history (35%). Your score is negatively affected if you have paid bills late, had an account sent to collection, or declared bankruptcy. The more recent the problem, the lower your score -- a 30-day late payment today hurts more than a bankruptcy five years ago.
· Outstanding debt (30%). If the amount you owe is close to your credit limit, that is likely to have a negative effect on your score. A low balance on two cards is better than a high balance on one.
· Length of your credit history (15%). The longer your accounts have been open, the better.
· Recent inquiries on your report (10%). If you have recently applied for many new accounts, that may negatively affect your score. Promotional inquiries don't count.
· Types of credit in use (10%). Loans from finance companies generally lower your credit score. FICO says this is most important when there isn't a lot of other information upon which to base a score.
Bring the credit cards current, or paying them off, or settling them at a discount all have about the same impact on your score. It is in your history and as time passes it will become less and less of a factor.
The one thing you don't want to do is do nothing.
