The importance of a having a good credit score
Fundamentally your credit score shows a lender, how credit-worthy you are. As a potential borrower, the higher your credit score, the better the interest rates you are likely to be offered. Whether you buy a car or a house, if you have a higher credit score, it is taken for granted that you are a responsible person, who makes payments on time, and therefore get a better rate than the person that with a lower credit score.
Monitoring and managing to get a good credit score maybe more important than you think. Your credit score will determine the interest rate you can pay on a home loan, a car loan, on credit cards as well as for insurance on your car, your health and your home. It can also swing things your way when you are look for a job or an apartment to rent. With poor credit you may be looked upon as someone who is not a reliable employee.
You could also fall prey to a lender who will see that you need the money and suddenly raise their rates. So you have to be able to control how much debt you have, check where your expenses and try to improve your credit score.
