If your interest rate is 5% and you pay off an extra $1000 on a 30-year note, you have just saved $50/year for the next 30 years. That is $1500!!!!
If you pay off your home early, it frees up what is often a very large portion of your monthly expenditures. You can then use that money to invest, give, and build wealth.
Besides, when you pay off your house, the grass crunches differently underneath your feet.
