Chicago or Milwaukee... What's better?

[Johann Kleisch]

I live about half way between Chicago and Milwaukee and plan to start buying 8-50 unit apartment buildings within one year. 

What market would be better to invest in over the next 10 years.  I know people can't predict the future, so what would you recommend based on the last 10 years.

Also looking for suggestions on commercial brokers in both markets.

Thanks in advance, best of success!
