Any tips for success for investing in the west side of Detroit's real estate market (especially lists of due diligence questions to ask before purchasing duplexes there)?

Congratulations on the success you have had with your 4 rental properties!

After that you will have two assets assuming your flip was successful. 

It has been extremely successful for me.

I am fresh to my career so I do not have a ton of money to put down.

I know a number of other people who have very good success with profitable vacation rentals here.

In the Los Angeles market, I'm still having success buying homes off the MLS (often over asking) by adding REAL value through additional square footage or starting from scratch by knocking an existing property down to build a bigger and better one. 

I’m thinking on starting a career as a real estate agent My question is should I consider the house market at all for where I start out?

@Howie Baker, I have been very successful at (so far) by calling property management companies and asking if any owners of MFUs are thinking about selling.

My end goal is to have passive income and financial independence when I finish my career (I love my job, don't want to leave early).But as I was saying; I already have a BS and now have a chance to get my masters.
