According to
this article, the median price of a house sold in Detroit in December was $7,500.
Another source estimates that the median is around $10,000, with the average listing price more than seven times that.
For comparison, the latter source pegs the median sales price in New Orleans as $103,172. It's difficult for me to picture what living in Detroit must be like if housing values are a tenth of what they are in a city that was devastated by Hurricane Katrina.
