So having reserve capital is something we have to take care of first and foremost before buying a facility.  

Mostly SFH/duplexes, but now own a mini-storage facility and getting ready to close on an office/warehouse. 

That especially true since it sounds like you are looking to buy a self-storage facility/business.

Infected cases remain relatively low in most areas across the US, but if you notice these figures are doubling every day - do the math and you can get to millions infected very quickly which will inevitably put a massive strain on our healthcare facilities (look at what is happening in Italy). 

Restaurant servers, cooks, those in retail, hotels and transport are literally out of work right now.

For this situation, how would you navigate finding out information while interviewing tenants like: where are you from, how old are you generally, where did you go to school, what do you like to do for fun, do you have a SO who will be over often, do you cook a lot, etc.?

We are all in this together.Keep in mind your tenant probably has money, but is choosing to pay it to someone else (suppliers, facility rent, employees).

I had to appraise an extremely large cash handling facility that was essentially a giant vault at one point in my short appraisal career.

Also in some of the models it looked like quarantine didn't really help the total infection rate just slowed it down to make hospital facilities less stressed... is that true?

Cook County and a couple of neighboring counties are generally:- Postponing court dates for 30 days- Sheriff's are staying eviction orders and sheriff's sale for 30 days- Moratariums on foreclosure judgments (some for 30 days)
