If you are looking to pay it off for retirement purposes, there was an article in best life talking about how you are wasting money by paying off your mortgage instead of putting it into a retirement account. You are putting a taxed dollar (.60-.70) into your house, when you could be putting a dollar (1.00) into your 401k. Worth a look.
paid off of course trading is not an income sport, its a waiting sport be expenseless while you wait.
Stock trading does not exist in a vacuum. Your comfort level for taking risk is surely affected by many other factors. Having a paid off house can increase one's comfort level if they don't have to worry about making a mortgage payment every month. On the flip side, I have seen sales people that could not perform unless something was about to be repossessed. Know thyself and then do what works best for you. Joe.
Pay mortgage off... what, are you NUTS? Give up your opportunity to piss'n moan for a federal bailout?
