Unfortunately there are always those who will prey on the few that either can't afford to repair their house or those whose homes are income/vacation homes. While it may seem insensitive, the truth of the matter is that there will be some homes that can be bought pennies on the dollar and if they are bought by investors they will be rebuilt relatively quickly because these investors want to see a return on their investment. Those folks that live on the island and have lost everything are the ones that might fall prey to selling only to realize they won't be able to buy anything they can afford and unfortunately become homeless.
