30-year mortgages beat 15-year mortgages for better financial results.
A 30-year mortgage with an investment plan can lead to better financial outcomes than a 15-year mortgage with a separate investment plan, especially in low mortgage rate environments. Even with higher mortgage rates, the 30-year mortgage may still be more beneficial for most borrowers. The advantages of a 30-year mortgage increase as the borrower's tax rate and risk tolerance rise.
