I don't know if it does or not.But I can share with you that Amex freaked out when they saw a mortgage on my CR. They immediately DROPPED my spending limits. The CL drops registered at a 9.8 on the Ritcher scale. I called them, pointed out that I had been paying way more than the required amount on my mortgage, etc. They would not budge.
When my mortgage was reported as paid off, and Amex did their annual review of my CR, the limits stayed the same, but they reinstated my flexible spending option. Since I have not used the Amex cards (those two) the lower limits didn't bother me. Since I pay off the Amex in full, every week, every month, I was miffed that the "option" of flexible payment was taken away when NOTHING had changed in my spending or payment pattern with them. It was a "privilege" that I had earned and felt cheated that they took it away from me. But that "privilege" has been reinstated. I still do not use it.
So for me, I am sure the score dropped.
But it does go back up after you start paying it down.
