Paid it off in ten years, 40 yr olds it was over. No More Payments !
But Good Luck if you go the long route.
Here's the thing. If the 15 yr and 30 yr are the same, let's say 5%, I'll take the 30 year and here's why.... I can always pay extra each month into the 30 year and pay it off earlier, in 15 years if I want. And I would pay extra in this low int rate environment. But, let's say in 5 years the inflation monster hits and we see 10% money market rates. Well then I'll gladly cut back to the minimum payment on the 5% loan and invest the difference earning me 10%. No brainer.
Now if I can get a better rate on 15 or 20 year then it's a tougher call. Always nice to carry a lower rate.
