When you have bad credit, many doors are closed to you. A poor or bad credit score is one that falls at or below 619 on the FICO score. You might not qualify for loans, or you might have to settle for less-than-desirable terms that cost you thousands of dollars during the loan’s terms. In some cases, poor credit can result in higher insurance premiums, and some employers check credit reports before deciding to hire you.
Of course, if keeping accounts open and having credit available could trigger additional spending and debt, it might be more beneficial to close the accounts. Only you know all the ins and outs of your financial situation, and like thumbprints, they're different for each person. Make sure you carefully evaluate your situation; only you know what can work best for your financial outlook.
