If you can afford it, you are far better off getting a 15 year mortgage instead of 30. It won't cost you much more, and the interest savings are truly incredible.
If you have a mortgage of $100,000 at 8% interest over 15 years, your monthly payment would be about $200 more, but you'd end up saving $92,083 in interest over the life of your mortgage!
Using these strategies is the easiest way to reduce your interest expenses and shorten your mortgage period.
