I've personally done 60 deals in Detroit this year and I've seen monthly property taxes anywhere from $20/mo (extremely rare) to $350/month.

Quote from @Kar Sun: My tenant's lease is coming to a close and I am relieved she will be moving soon.She has been paying on time but has been extremely unpleasant and rude.While the money does not smell my mental sanity is more important than money in this case.She sent me a registered letter stating that she feels "unsafe because we have not done the fixes the way she wanted it".She requests to have her witness for a walkthrough.In my state a walkthrough is required but I am not about to grant it to her to bring any witnesses as that is not in my contract.If she feels unsafe she does not have t be present.I also do not treat a final walkthrough with a tenant as a final sign off.This walkthrough does not include a detailed inspection of the plumbing and the appliances that will be done after she departs.This is simply for the visible cosmetic issues and should take less than 1 hr.  

is it through cold calling myself, through broker relationships, or a mix of both?

Any advice on this would be extremely appreciated!

Seems a little extreme.  

You can use Spokeo for cheap to lookup owner's numbers. 6 deals out of 191 was extremely good! 

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.The City of Detroit has 183 Neighborhoods we’ve analyzed.PM us if you’d like to discuss this logical approach in greater detail!

You can make SFR work but extremely tough in traditional sense.

What made us more suspicious is that they insisted that our team send POF exposing our full account numbers which they were extremely insistent about. 

Heat takes a toll on them, cold takes an even bigger tole, and it's all so dang toxic how there manufactured, making it hell for recycling or disposal.
