As I understand it Habitats for Humanity has been working in Detroit dismantling homes. Seriously.
I remember seeing all those places, I grew up in Detroit and didn't move out until a year after I married.. At that time, to buy a house in the city was more expensive than buying in a new suburban sub-division. It sure isn't like that anymore...Detroit was once a beautiful place. Many called it the Venice of the country...You wouldn't believe that looking at it today...
Example: The first house we bought after marriage was a 3 bedroom ranch about 20 miles N. of Detroit and it cost only 13,900.00 sticker shock: That was in 1960.
You couldn't buy any home in Detroit for that amount of money....its sad what has become of that place...
