Even if you know relatively little about how FICO scores work, you've most likely heard that when your credit is pulled it hurts your scores. I've actually found this to be the primary reason people avoid applying for new credit. In fact, friends often ask me how I manage to apply for so many of the rewards credit cards I rate and review on Creditnet.com. Shouldn't all those credit inquiries be killing my FICO scores? Well, they haven't, and I frankly don't worry about credit inquiries that much. While there's no doubt in my mind too many inquiries can hurt FICO scores, I think most of us overestimate just how big of an impact credit inquiries have on our scores.
