The biggest things that hurt your score are paying bills late and borrowing too much money. If you max out your credit cards or are constantly late on payments, your score will drop. Other negatives include having too many new credit applications in a short time, defaulting on loans, or having accounts sent to collections. These actions signal to lenders that you might be a risky person to lend money to.

Credit unions are not-for-profit and owned by their members, so they often have your best interest in mind. They usually offer credit-builder loans with lower fees and better interest rates than many banks or online lenders. They are also more likely to work with you if you’re just starting out or have a thin credit file. People often say credit unions feel more like a community, which can be less stressful when you’re new to building credit.

Whether you’re downsizing or moving closer to family, good credit makes it easier. If you want to rent an apartment in a nice community, landlords will check your credit. A high score makes you a more attractive tenant. If you’re considering a reverse mortgage or a new mortgage for a different home, excellent credit gets you the best possible terms and lower fees, leaving more money in your pocket every month.

You can get a free copy from each of the three major companies—Equifax, Experian, and TransUnion—once every year. The only official website to do this is AnnualCreditReport.com. It’s safe and approved by law. Don’t use other sites that try to charge you. Checking your own report this way does NOT hurt your credit score. It’s a smart habit to check all three, as they might have slightly different information.
