Every time you apply for credit and a creditor pulls a report it hurts your FICO score. The rule is to have no more then 6 inquiries on your credit report with in six months. They say a hard inquiry pulls your score down 3-5 points. There are 2 different inquiries hard and soft. A soft inquiry is when you pull your report or a creditor you already have pulls it to make sure you still have a good profile. The hard inquiries are the ones that hurt your score. It means that you are applying for credit.
