Hard inquiries and rate shopping
Shopping around for the best mortgage rate or car loan rate may sound like a terrible idea if you take a five-point hit every time you apply. But there's actually an exception baked in for these events. When you're rate shopping – that is, trying to find the best loan rate possible – all the hard inquiries for certain types of loans will count as a single pull within a particular window. That window can vary from 14 to 45 days, depending on the credit scoring model, so it's safest to do all your rate shopping within two weeks.
Usually, rate shopping is allowed when you're seeking to borrow money for a specific purpose, like you're shopping for a mortgage, auto loan, or student loan. The assumption is that you only need to borrow money for one purpose and aren't simply looking to rack up a lot of debt, as could be the case with multiple credit card loan applications in a short period.
