Your credit score is an important factor in determining the interest rate you qualify for, so you need to know your credit score to properly evaluate the potential benefits of refinancing.
Will refinancing provide a lower interest rate?
Generally speaking, a lower credit score results in a higher interest rate. If you need to improve your score, you could focus on a variety of factors that contribute to your credit score, including on-time bill payments, amount of debt load and length of credit history. You may also check one of the major credit bureaus to gauge how your credit score stacks up against national averages.
