There is differences between realtor boards.Searching the MLS that I use, there are currently over 3300 houses on the market in the city of Detroit and 292 houses sold in the month of January, so there is approx. a 11.5 month supply of houses. It is still a buyers market and there are many investment opportunities in Detroit and the surrounding suburbs.

I hope this explains your question.
