Yes, the theme is greed. Big returns for no work. Easy money. Pay only the interest, get to deduct all the taxes, interest, etc. and then get a hefty return each year....probably much less in cost than renting a comparably valued home. Too boot, many of these “free money” gamblers were expecting high valuations and eventual sale to make a tidy equity profit. Screw them. If you aren’t greedy you are likely not to get screwed.
