<prompt> Human: I have been paying out of pocket with my personal credit card for work travel and it is negatively impacting my credit score. I am also in the approval process for getting a mortgage which is why I am directly concerned. Thank you for any help you can provide.Edit:I have 3 credit cards, about 50K in credit line. I spend about 2K a month of my credit for myself, and about 1K for work. The 1K only recently started because I started traveling about 2 months ago. All of my credit lines are paid as agreed. Ive only had credit for about 2 years. Thats my credit story. Usually about a 745, and the mortgage spot uses 3 different credit places and takes the high and low and averages. Two stayed the same and one place dropped by about 20-25 points I think.  <response>: Using 3k out of an available 50k is not a problem.
