This is a massively complex issue, spanning law, epidemiology, economic, healthcare, finance, politics, manufacturing...areas no one person can have mastery, with far reaching second and third order effects that can't be encapsulated in the low fidelity ideas of "Shelter in place= the only option" or "give me back my civil liberties NOW rah rah Ayn Rand" Complex ideas require the ability to be nuanced and understanding that the other side may also have a point of view which you may not agree with because you don't comprehend it well.

I have a handful of mobile homes/manufactured homes in the San Antonio, TX area. 

My new interest is investing in manufactured/mobile homes, and mobile home lots/subdivisions.

All complimented with Amazon fulfillment centers, google, and more tech manufacturing jobs.The bad reputation of “Detroit” comes from OOS investors wanting sub $40,000, D class properties in poor condition, because they pencil out to 2-3% deals on paper.

Many of the units you'll find on your flips still use Freon, which is no longer being manufactured as of 2020.

Escrowing Taxes and Insurance is required by federal law and has been since October of 2010 on almost all manufactured homes - including chattel loans.

Turns out auto manufacturers are making wire covering out of soy and other products that is "rat food" and making the rodent / auto problem worse.   

But, if you guys can afford to do the septic and any other improvements, you can probably make a profit just by doing that.If you can't afford to finance the improvements, you might look into wrapping the loan up with a construction loan.Sometimes, you can even get a FHA loan to do so.Another option would be to get a loan from a manufactured home dealer.  

It is sad, but having dealt with older people in the same situation, they will manufacture or amplify problems just to gain human interaction.

While China is slowly bringing back employees to work manufacturing, supply chain, etc., they are not out of the woods by any means.
