Keep Your Credit Score High
"When credit markets tighten, if anyone is going to get approved for a mortgage, credit card or other type of loan, it will be those with excellent credit. Things like paying your bills on time, keeping your oldest credit cards open, and keeping your ratio of debt to available credit low will help keep your credit score high."
Credit Cards and Credit Scores
"If your credit card balances go unpaid, your credit score will start to diminish. The next time one of your insurance policies is up for renewal, you may get hit with an unexpected rate increase. Insurance companies that check your credit score when considering your premium seem to assume that if you can't pay your bills, you might be letting your car or home maintenance slide, or you might be an irresponsible person in general, all of which could make you a higher risk by increasing your odds of filing a claim. Some employers also run credit checks on potential job applicants, and an employer who is concerned enough to check your credit score will probably be concerned enough to not hire you if it's poor. If purchasing or refinancing a home is in your future, your credit score is particularly important, as it will determine the interest rate on your mortgage, or whether you're even eligible for a mortgage at all."
