^ I like the flexibility of a 30 year.
Yeah, you'll pay a lot more interest if you stick to the minimum monthly payments for all 3 decades of a 30 year, but most 30 year loans let you pre-pay princincipal if you want to, which can get you pretty close to a 15 year if you're disciplined and consistent.
However, on the other side of the coin, a 30 year sure comes in handy when your wife quits her job to start her own business and then you get laid-off and your income drops to zero for a stretch of time.
