LENGTH OF CREDIT
Your length of credit is how long you have had credit. At face value, those seems like something you couldn't really do anything about. However, there are ways that you could hut yourself here. If you close out your older cards, even if they have higher interest rates, it will hurt your credit score. The credit scoring modeling has not memory of credit cards you close. If you close out that 15 year old card you will get no credit for it!
