Allow me to speak for the Flint situation, I live here. As the city continues to deal and work to fix this situation, we are all still here and living. I have run across a small number of people that feel they need to move or are planning to move. The vast majority, 90%, are still here. Many people speak on this situation and how it relates to investing but are not here. The lead situation is bigger than Flint many cities across the nation are and will have to deal with this structural problem at some point in the future. The difference is that it won't be so widely covered and the powers-that-be will take proper steps to correct it before it gains nationwide coverage. Our powers chose to take shortcuts that didn't solve anything.
So with that being said, if you know personally yes share and hep educate fellow investors. If you don't seek accurate knowledge from those on the front lines. The market will never be as hot as Florida but as far as buy and hold's go, people still live here and will need a place to live. The market is still here and maintaining not much has changed regardless of the water situation as far tenants.
