Michael Douglass: Daryl asks, "Will asking for a line increase account as an inquiry?" I'm taking that to mean increasing the amount of credit available to you on a credit card. I can actually answer this for me personally, because me and my wife were talking to our credit union about this and they said, "Well, sometimes it will result in a hard inquiry, and sometimes it will result in a soft inquiry, it just depends basically on how our automated system works." The fact of the matter is, it may. That's something, when asking for that, you need to consider. In my shoes, for a minute. I'm looking to reduce my credit utilization in part because I'm planning to, hopefully, buy a house in the next year or so. It would be worth it to me, in my personal circumstances, to go ahead and get that increase, even if it resulted in a hard inquiry and reduced my credit score by a little bit for a couple of months, because I'm not planning on buying a house tomorrow, I'm planning on doing it six to nine months down the road when, frankly, that should be largely rolled off as an issue. If you're trying to buy a car tomorrow, it's a different ball game.

Nathan Hamilton:
Yeah. And more times than not, there's not a hard inquiry. It depends on the bank. What I would ask is, when you're looking for a credit limit increase, just ask your bank, is there a hard inquiry for this credit limit increase, to see if it's available? If there is, OK, then there's a potential impact. If not, then you're more than fine, and there is no impact, there's nothing reported to your credit report.
