Investing in Milwaukee or Madison WI

[Sebastian K.]

I was looking at homes in both Milwaukee and Madison WI to see how the market is there and I am finding multi family homes ranging from $4,000 to $100,000 in Milwaukee and $100,000 to $200,000 in Madison.  Why are the multi family homes so affordable in those towns?  I know Milwaukee made the top 10 list for the unsafest city to live in, however, Madison is considered a great place to raise a family.  Can someone who knows those areas share some light on these topics and if possible share some areas within those towns that are invest worthy. 

Thanks again.
