15-Year Mortgage

  • • Lower interest rate
  • • Build equity faster
  • • Own home sooner
  • • Psychological benefit of being debt-free

Disadvantages

  • • Higher monthly payment

When to Choose Each

Choose 30-Year If:

  • • You're early in your career with income growth potential
  • • You want flexibility for other financial goals
  • • You can invest the payment difference for higher returns
  • • You plan to move within 7-10 years
  • • Your budget would be stretched by the 15-year payment

Choose 15-Year If:

  • • You're established in your career with stable income
  • • You want to be mortgage-free before retirement
  • • You value guaranteed interest savings over potential investments
  • • You plan to stay in the home long-term
  • • You can comfortably afford the higher payment

The "Best of Both" Strategy

Can't decide? You can get a 30-year mortgage and make extra payments as if it were a 15-year. This gives you:

  • The flexibility of a lower required payment if needed

  • Most of the interest savings of a 15-year term

  • Freedom to skip extra payments during tough months
