Credit Scores are deceivingly important. Here’s why: Let’s say you go out to buy your dream home and get a $500,000 mortgage only to find out the late payments you had in training made your credit score fall to below 700 points. The difference between the best rate and the rate the banks will now offer you might be 0.50%.  For most mortgages that’s a difference of around $150 per month or $54,000 over a 30-year period of time. Ouch!
