At 6.85% over 30 years, the principal-and-interest payment is about $19,657.78. A 15-year term raises the payment to roughly $25,396.82 but cuts total interest sharply.
Over a full 30-year term at 6.85%, total interest is roughly $4,076,801 — often more than half the loan amount. Extra principal payments reduce this substantially.
No. This is principal and interest only. Your full monthly payment also includes property tax, homeowners insurance, any HOA dues, and PMI if your down payment is under 20%.
