Will having no credit cards or outstanding loans improve a credit rating over time or is having at least one account that is current better?

You have to have credit in order to have a credit history and a credit score. Every consumer needs at least one installment account and two revolving accounts that are managed properly for optimal points during the calculation that produces a credit score. It can be harder to get the credit you need, such as a mortgage loan, with no credit history than when a borrower has bad credit. Also, if a consumer has bad credit; positive, ongoing,accounts will offset the negative information.
