Well it depends actually. In my case they reported both, but my company is an LLC (taxed as a sole proprietor, but with its own tax id), I think if you have an S or C corp, then it only posts to your biz CR.
*I used to dread being a member of the 700 Club because I thought it came included with a Pat Robertson blow up doll... the very thought scared me into bad credit.*
I also am a LLC so we will see. None of my others have posted to personal so I didn't figure this one would. I hope not we are in the process of building a home and really didn't want any new accounts showing up but I guess if I show it is for business and not personal it shouldn't be a problem. Maybe I will have to ask over on the mortgage forum ar ask our LO.
