WHAT ARE THE ADVANTAGES OF 15- AND 30-YEAR LOAN TERMS
30-Year:
  In the first 23 years of the loan, more interest is paid off than principal, meaning larger tax deductions.  
  As inflation and costs of living increase, mortgage payments become a smaller part of overall expenses.  
15-year:
  Loan is usually made at a lower interest rate.  
  Equity is built faster because early payments pay more principal.
