Crackpot. So many things wrong with this. First of all, debt isn't evil. Interest only compounds if you pay less than the interest every month. Most mortgages require you to pay all of the interest and pay down the principal every month. The extreme is interest-only mortgages, but even then the interest isn't compounding. Most people cannot and should not build their own house: "then save up enough money to build a house with your two bare hands and some help" Present value of future payments is LESS than the nominal value.
