Credit score affected by interest rate shopping
The Thirty-Day Grace Period and Other Credit Inquiry Facts and Myths
By Robin Holland

Credit myths are common in the credit-reporting industry, and we often see them when consumers call us with questions:

Why did the credit-reporting agency deny my credit application?
Why did the credit-reporting agency change my score?
Why did the credit-reporting agency put false information on my credit report?

And then there are questions about supposed myths of the credit-reporting process. I recently received this comment, from Marcy, on a previous blog post:

I’ve been in the process of a refi. I have worked with 3 companies in the same 30 day period (I always get 3 quotes for any job). I always heard that if you have multiple inquires within a 30 [day] period for the same thing (refi) that the inquires would NOT affect your score. The last credit score I received a copy of, my score (Equifax) had dropped 10 pts, with Experian it went from 818 to 792-the reason “too many inquires…” Is the 30 day period a MYTH?

The 30-day grace period is not a credit myth. It’s probably a smart idea to compare rates and check out loan offers from several lenders before making a purchase of a car or a house.

Under normal circumstances, if you apply for a mortgage or an auto loan, any inquiries related to that application made within 30 days count as ONE inquiry. Even if you visit twenty lenders and all of them pull a copy of your credit report, those twenty inquiries should count as only one inquiry.

I don’t know what other activity Marcy has on her credit file, but some inquiries will affect your credit report differently:

Personal Credit Inquiry: If you pull your own credit report, it will not affect your score. You can check your credit report every single day, and it will not make a difference in your credit report or credit score.

Soft Inquiry: When someone other than you accesses your credit report, but you did not initiate the transaction, the inquiry doesn’t count against your score. One example is a promotional inquiry, in which a creditor or lender looks at your credit report in order to give you a new credit offer or a different rate. This promotional inquiry should show up on your credit report as a promotional offer, which makes it clear that you did not initiate the request. Soft inquiries don’t affect your credit score during a hard inquiry, which is when you give permission to a credit grantor to pull a copy of your credit report (see below). If you want to prevent creditors from accessing your credit report, you can opt out of these promotional offers.

Hard Inquiry: Any request for a copy of your credit file is an inquiry, but a hard inquiry is the only one that can affect your credit score. A hard inquiry is one in which a bank, a landlord, an a mortgage broker, or another creditor or lender accesses your credit file because of a transaction you have initiated.

  1. Sheena, Ohio says:

    I recently went car shopping, and I had a score of 670, within 30 days I had 2 inquiries on my report, after checking my credit scores again all three ranked below 560, carefully reviewing my credit reports, I just cant see how my scores dropped so low, after shopping for a car, and applying for one credit card.

  2. Mittens says:

    I recently purchased an SUV from a reputable local GM dealership. From this one purchase I have 18 inquiries on my equifax credit report. All 18 report as being made within the same 2 day period. When I disputed, 17 of the 18 inquiries, online with Equifax, I was only given the option to choose 1 of the 2 reasons for my dispute. (1) I did not authorize or (2) this is a fraudulent inquiry. Equifax response was that they had determined these inquiries to be reported correctly and Not 1 of the 17 has been removed from my report. If the 30 day rule is not a myth then why doesn’t Equifax add a 3rd reason for dispute such as auto loan Inquiry or …
