Many of these markets are very well represented by sellers & turnkey operators here on BiggerPockets.

Detroit is appreciating rapidly, due to many factors, and it still cash flows or at least allows you to operate near break even.

Turn-key operators, etc. 

Lenders see all, including how little margin some flippers are operating on.  

I'm not sure how experienced you are in the real estate world but one thing to remember when you are getting into RE investing is to have your team of people or as Brandon Turner from the Bigger Pockets Podcast calls it your CORE 41.

They literally went through each operating agreement and prepared an email listing out each member of each LLC and clarifying they each had to guarantee the loan despite the fact none of those entities were even being used for the purchase (which was previously explained to Dominion Financial). 

I would suggest building your CORE 4 which consists of a great realtor, contractor, property manager, and attorney after you choose where to invest in.

Search the archives; plenty of content on the forum on sober living operations.

Of course, always check recent reviews.. they tell you more than a flashy website.Size Matters: I’d avoid both extremes... massive firms managing thousands of units and one-person operations juggling too much.
