Thanks @Russell Brazil and @Andrew Postell ! Good info. I did not know mortgage credit checks were lumped into one hit if they are done within a short period of time. Years ago when I applied for financing for a vehicle, I told the dealer to use my personal bank only for financing for the credit check, but a couple weeks later I noticed on my credit that they ran checks with four different lenders in that one day and all of them showed up on my credit report. Perhaps the rules are different with auto loans, but I have been scared to have anyone run my credit after that experience ;)
As far as my credit score goes, between free viewing from the three different bureaus, free "FICO" scores from two credit cards, and Credit Karma, they were all different between 806 to 838 last month, so I just averaged a round number at 820. But to your point Russel, when I rolled a HELOC into a mortgage a few years ago, I did notice the credit score they used was on the lower end of where I "thought" my score was based on the free scores I was viewing from other sources.
Thanks again for the tips, fellas!
