Credit can be a beneficial tool, when used responsibly. Many people can’t buy a car, home or other big-ticket item without using credit. The following tips will help you build a positive credit record and maintain a solid credit rating.
Establishing a solid credit history is crucial as it lays the foundation for various financial opportunities. A good credit score can unlock doors to better interest rates on loans, more favorable rental terms, and even certain job opportunities.
The sooner you begin establishing credit, the better. Length of credit history is a factor in credit score calculations, so having a longer history of responsible credit use can be beneficial.
