The credit check is reported to the credit reporting agencies as an “inquiry.”
Did you know that you can shop around for a mortgage and it will not hurt your credit? Within a 45-day window, multiple credit checks from mortgage lenders are recorded on your credit report as a single inquiry. This is because other creditors realize that you are only going to buy ONE home. You can shop around and get multiple preapprovals and official Loan Estimates.
NOTE: Your credit score is impacted by very few points.
