He abandoned it during his demon years so his best friend took it over and added a couple more people before it desolved due to all going off to college.In college he had a side hustle of finding things on free sites, putting them up for sale, selling the free item and offering to transport it for a modest fee.  

So if lots of parking, ideally walking distance to busses or transportation to cut down on cars, you might get away with it (legally).Operationally;  this is a can of worms to manage. 

Find local specialist in your area is huge.2. close to public transportation.

Also who wouldnt want to work for an hourly wage, under the direction of someone else without the hassle of buying and transporting materials or the responsibility of permits, inspections and the like.

However cash is a hard no for me because I feel having it around and transporting it provides a security risk for me.

It's not the same - you have to deal with transportation, storage, through put cost, counterparty risk, the need to find an end buyer in the right location with the demand at the right time, collections and billing on giant sums of money, etc. 

My own observation leads me to believe that a large part of the buyer agent’s time budget gets spent on showing houses and transportation to and from those houses.

I am confident that “Drill Baby Drill” (aka reducing the price of oil, aka reducing everything that is transported) will directly impact the cost of goods thus increasing tenants and buyers purchasing power.

Other large employers are health, education, as well as transportation and warehousing. 

We can transmit electricity reasonably efficiently, and then we can transport actual material (ie: water or natural gas) reasonably efficiently.
