Will multiple credit checks hurt my score?
Typically, credit bureaus recognize when a person has multiple credit pulls from a mortgage company that it’s because they’re in the midst of mortgage shopping. Usually, they allow a two-week window where they’ll allow for the potential buyer’s credit to be pulled multiple times without it hurting their credit (although this isn’t guaranteed by every lender).
However, if you’re only having your credit pulled once or twice it shouldn’t affect it. (Even if it goes down slightly, it’s usually temporary.)
