Your payment history accounts for about 35% of your credit score, and a couple of missed payments can really hurt your score. Most consumers don't know you can request creditors stop reporting missed payments to ratings agencies if you have an otherwise clean record. This is called a good-will adjustment. Write a letter to your bank or card issuer emphasizing your past good payment history and asking politely to stop reporting the missed payments. Of course, this trick only works if you have a pretty clean record already, but you can remove those few blemishes that holding back your credit score.
Some of your creditors and lenders might report only to one of the credit bureaus. And, since credit bureaus don’t typically share information, it’s possible to have different information on each of your reports. Ordering all three reports will give you a complete view of your credit history and let you repair your credit at all three bureaus instead of just one.
This is easier said than done, but reducing the amount that you owe is going to be a far more satisfying achievement than improving your credit score. The first thing you need to do is stop using your credit cards. Use your credit report to make a list of all of your accounts and then go online or check recent statements to determine how much you owe on each account and what interest rate they are charging you. Come up with a payment plan that puts most of your available budget for debt payments towards the highest interest cards first, while maintaining minimum payments on your other accounts.
