I’m (Mostly) Debt Free. What Do I Do with My Extra Cash?

A friend recently asked, “My husband and I have paid off our student loans and car loans. This has been done over a 5 year period. We are now in a position where we have some extra income. The only debt we have is our mortgage. We have a good nest egg of savings for emergency. If we go at the rate of paying off debt as we have over the past 5 years, we could pay off our house within 4 years. Should we hurry and pay off the house, or invest our money in other places?”
