I don't know about that. We have never kept a balance on a card, pay everything early, never a penny interest, never late on the mortgage, etc. When I applied online for the Disney Chase, I was approved immediately. I got $3800, which was kind of low, but didn't matter much since we would never reach that mark. We applied for a Lowe's card last month to get the 12 months no interest on an installed fence, and got a limit of $12500. The manager running the application was stunned and said she had never seen a limit that high, and that more than half of the people applying for cards there get denied. So that rule doesn't hold true for us, since the second network approved us for more than triple the first.
