re: Financing a purchase via 0 interest credit cards

If I pay my only CC off every month, would I put 0 for the balance or would I put the total of the balance as of my last statement? I always have a balance, but never a balance carried over.

The range predicted includes my current score, though it is on the higher end of the range. The lower end is 45 points lower, so you're pretty close.

Let's say I have a 775 and my wife is at 820. Would it be better for us to retain her high score and do this in my name, or do it in her name to keep us both as high as possible? Or would it impact us both since we are married?
