Big second on paying the mortgage off early. When I bought my post-divorce house it was my goal to pay it off early. I'm not where I'd like to be (in large part because of the unexpected kid expenses my ex has stuck me with) but still, I only owe less than 1/3 of the current value of the house, which is a comfortable position to be in. You're young enough that you could start adding a little bit to your mortgage payment.
