@JayKay : Yes those are monthly numbers. Below is more information from bank. Let me know if i am missing anything.
Ok, so it looks like you had things backwards then. You said your 30 year was about 2400 and your 15 year was 1800, which seemed wrong. Your new amounts look correct.
Anyway, my take on it is usually to go with the 30 year rather than the 15 year unless the rate difference is quite large (which yours isn't). Here's the reason:
If you were to get a 30 year and pay it off in 15 years, calculations I've seen show the amount of interest paid is nearly the same as just getting a 15 year. But the critical difference is that you've got wiggle room. If you've been paying extra in your 30 year but then your income were to fall or disappear because of disaster, illness, etc, you could reduce your monthly payments with a 30 year, which could make a huge difference in your well-being. But with a 15 year, you're stuck with that higher payment regardless, which could put you into a much worse position.
That's why I always go 30 year, not 15. It gives you options.
