Should I withdraw money from my IRA to pay off my house?

I have met with a lot of people that like the idea of taking an old IRA or withdraw money from their 401k to pay off their house. A lot of times it doesn't make sense financially, but try stopping someone who has already maid up their mind. Luckily you can quantify the effects of this using the cash flow projector. By taking a one time withdrawal from your retirement accounts, it will calculate the additional taxes you would owe. That way if you or a loved one is bent on doing it, they can at least put a number to it and compare the two scenarios.
