Changes are coming to your FICO score. Why should you care? Well, your FICO score goes a long way in determining what types of loan(s) you can get and what interest rate you will pay. If your FICO score is good, then you will generally get favorable interest rates and terms. If it's not so good, you may not be able to qualify for a loan, and if you do in fact qualify, your interest rate will probably be higher than someone with a good credit score.
