Wait 2 years from applying for CCs to apply for a mortgage? I've never heard that before, only 6 months.
I'm sorry. I meant having a hard pull in the past 2 years, - but more than 6 months ago, - from what I understand, would actually benefit you. That being the case, if you don't have any hard pulls on your report (from the past 2 years), it might help you to get a hard pull in now.
This is based on some research I've done over the past 2 days - a lot of reading over a few sites, so I can't quote a source. I know this may not be helpful to some, because I'm not actually giving an answer, but I am saying to look into that specific aspect.
