The major risk I see in harming the price of multifamily is deflation caused by an economic downturn.  

  $50k in tech stocks, $50k in energy stocks, $50k in consumer Staples,$50k in bio/health care, and $50i in basic materials.

I've read the articles and forum posts on developing mobile homes parks and understand why they aren't economical in this day and age, how most townships won't work with you, how the demographics don't work in areas where it's economical, etc... and I agree!  

I have heard both sides - half of the people saying RE will trend upwards for several years given gainfull employment opportunities and a adventageous business climate along with a continued shortage of housing; I have also heard to wait to invest until around the 3rd quarter of 2019 when housing is more abundant and the economic trend demands a downward curve. 

My concern is for potential health risks down the road. 

I'm sure it can be proven to have health implications over time if breathed in constantly, but it's not like asbestos, and even that is overblown in our society.

Looks like at first glance it's intent is to serve as a market driven investment vehicle that focuses on certain areas that are likely struggling in the economic value/equity arena (sometimes these areas are the best opportunities but obviously one needs to be careful).Again at first glance I'm wondering if opportunities exist for those prepared to start a fund and execute (flip, rent, etc) properties within these zones, but also it appears intent is for these funds/investment products to exist for more passive investors. 

Think of how many abused and battered felines you could nurse back to health with a property like that.
