No.2 Checking your FICO score can hurt your credit

Unfortunately, I heard this one from a mortgage broker who is otherwise pretty smart. He was confused about which type of inquiries hurt your score and which don't.

Applying for new credit is generally what hurts your score. Ordering a copy of your own credit report or credit score doesn't count. Those mass inquiries made by credit card lenders, who are trying to decide whether to send you an offer for a pre-approved card, also aren't going to hurt you, either -- unless you actually take them up on their offers.

If you want to minimize the damage from credit inquiries, make sure that when you shop for a mortgage you do so in a fairly short period of time. The FICO score treats multiple inquiries in a 45-day period as just one inquiry and ignores all inquiries made within 30 days prior to the day the score is computed.

For most people, one inquiry will generally knock no more than 5 points off a score (and scores typically run from 300 to 850, so that's not a big percentage).
