Here are some helpful tips on keeping a high credit score:

1) Keep all credit card balances under 30% of your limit.  For example, if your credit card limit is $10,000, never keep more than $3,000 on it.  The debt a person carries on a credit card is called the “utilization rate” and credit bureaus respond more favorably to low utilization rates.

2) Have at least three revolving credit lines.  Credit bureaus give higher scores to those with three major credit lines (American Express, MasterCard, VISA or Discover).  If you have open cards, and don’t use them.  Don’t close too many of them or it may hurt your score.

3) Verify that your credit card reports your credit limit, many don’t.  This assures when your credit score is run, you’re utilization rates are proper.
