Don't have a business degree, and therefore do not claim to be an expert in this field - ANYWAY - I question this approach. At recent interest rates I was able to consoidate at under 4%. After a few years, my interest will fall to about 2.75%. Life of this loan is in the neighborhood of 30 years.
I plan to pay as little as possibe on this loan at this rate as I can. I suspect that inflation will continue to increase, and expect that the return on my investments will provide greater than 3% gains per year. I plan to contribute to my retirement as much as possible, and to keep consumer/auto debt to zero. As for my house, seems like a mortgage payment is a benefit to the taxes. Finally - GOD FORBID - If my life is cut short for whatever reason, my loans expire with me. I'm not banking on this apporach, but if it were to happen, I would like to know that I provided as much for my family as possbile (House, college, insurance, etc.) than paying off my school expenses.
Bottom line, paying off the big and scary educational debt quickly seems to be the wrong focus. I will be more concerned about making greater returns on my assets.
