- ✅ You can comfortably afford higher payments
- ✅ You're focused on long-term wealth building
- ✅ You want to be debt-free faster

Alternative Strategies
Get a 30-Year But Pay Like a 15-Year
Take the 30-year mortgage for flexibility, but make extra payments as if it were a 15-year loan. This gives you the best of both worlds:
- Lower required monthly payment
- Option to pay extra when you can
- Flexibility to reduce payments if needed
Expert Tips
- Start with a 30-year mortgage for flexibility, then refinance to 15-year when your income increases
- Make bi-weekly payments on a 30-year loan to pay it off faster
- Consider your age - if you're 50+, a 15-year might be paid off by retirement
- Factor in other financial goals like retirement savings and college funds
