A house a couple blocks away collapsed when it fell off its jacks while the owners were laying a new foundation. Thoughtful contractors, willing to lend a hand, stuck their business cards in the pile of gravel out front. This was a one-bedroom, 870-square-foot cottage that sold for the obscenely low price $525,000 last year. One corner of the house poked into the neighbors to the east, while the other corner slewed over into a narrow mini-park.
