It's really depended on how long will you live the house..

Your question should categorize in

1. your age (no one want to have mortgage payment while you retie). If age < 35, 30 year loan would be good.

2. how long do you plan to live (if you plan live < 3 yr, you should 30 years loan)

3. your monthly payment over 40% your monthly income? Do you let your mortgage payment over 40%

4. If you are high income class.  30 years is better choise.
