A tradeline is a credit card or loan that can be added to your credit report for a short period of time, typically a few weeks. While they only stay on your report temporarily, tradelines can add anywhere from 10 to 100 points to your score. By boosting your credit score through tradelines, you may be able to qualify for better rates and terms on loans, or improve your chances of being approved for a mortgage or car loan. Think of it as a strategic investment in your financial future – by spending a little money on a tradeline now, you could potentially save or earn more money down the road.
