With an opportunity like that you may want to consider this area for now. 

I get more use out of big data in other investment categories, which provides a nice baseline for the kind of returns I should expect on real estate, before it's too much effort.Granted, there are a million opportunities out there.

@Andreas Thuresson like @Jennifer Hyman said the opportunity is limited in north suburbs unless you are going far north suburbs near Wisconsin.  

It depends on our own dispositions.While hunting for deals online,i stumbled upon a great opportunity.

When I was earning a lot more than I needed, it was easy to take the risk with disposable money.I want to quickly point out that in order to really take advantage of getting these seemingly tremendously lucky deals, you need two things:1) Recognize the Opportunity and2) Be prepared (usually by having the money for it)When I started working in my professional IT Job, that gave me the preparation part.When I started learning about the financial calculations, especially Future Value, NPV, DCF, etc.

There are opportunities in rent controlled housing because those buildings are artificially worth less than they “should” be.

There are many opportunities for cashflow rental properties.  

We have around $150k equity in our home and are considering selling and using the cash to move into a property that will give us an opportunity to generate some revenue through house hacking or finding something with a guest house or apartment we could rent out. 

A good market for me includes at least 1Million population with low unemployment, good jobs, cheap houses and business friendly and fiscally responsible city / state (check their credit rating).

I needed a place to live and could not justify paying rent when opportunities were available.
