Most homeowners would love nothing more than not to have to put that mortgage check in the mail every month. But trying to pay off your mortgage ahead of schedule is not something to be undertaken lightly. You must make sure you are financially secure, with no other significant debt, and have money in reserve for emergencies. Learn to calculate your Debt to Income Ratio.
There are also compelling arguments for not paying off your mortgage ahead of schedule. If you are inclined to take some risks, you could invest the money instead. Your investment could conceivably earn enough money to offset the benefit of paying off the mortgage.
Or maybe you would just like to enjoy your money now. By allotting less of your income toward your mortgage, you have more money available for vacations and other uses. Or you could use the money for home improvement, which can make your home more comfortable and more valuable when you are ready to sell.
