Which Should You Choose?

Choose a 15-Year Mortgage If:

  • ✅ You have stable, predictable income
  • ✅ You can comfortably afford higher payments
  • ✅ You're focused on long-term wealth building
  • ✅ You want to be debt-free faster
  • ✅ You have emergency savings established
  • ✅ You're nearing retirement age

Choose a 30-Year Mortgage If:

  • ✅ You're a first-time home buyer
  • ✅ Your budget is tight
  • ✅ You want maximum financial flexibility
  • ✅ You have other high-interest debt to pay off
  • ✅ You want to invest extra money elsewhere
  • ✅ Your income is variable or commission-based

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
