I don't have a mortgage or car payments and my score is around 820. One time I went close to the limit on the credit card and it dropped a 120 points, but it went back up as soon as I sent payment.True. I was showing "negatives" for not having a mortgage. The other thing which was lowering my score was "high credit card balance". Even though I pay off the balance every month. So I started paying the credit card bill before the closing date.
It's all just a game.
