When you’re considering a balance transfer between credit cards, remember to close the original card after transferring the balance. Many people forget this and end up with two large balances later on. Balance transfers often come with fees, so weigh these against the savings from the lower interest rate. Additionally, each new credit application triggers a credit score review. Too many reviews in a short time can lower your credit score. It's important to manage these factors carefully to avoid increasing your debt or impacting your creditworthiness.
