My objection to mortgage systems is that they front load the interest, which measn that if the market remains at current values, the house does not appreciate you any value though you put tens of thousands into mortgage payments. Until year ten in a thrity year, you’re paying basically all the thirty year interest up front. If you can afford the fifteen year, you still pay most of the interest up front but your payments do reduce the balance due more rapidly than in a thirty year.
One thing that I've seen around here is that people get mad when the house goes into foreclosure and trash it. Some people have moved out and left their pets in the house to destroy it and ultimately starve to death.
