We live in a society that you can earn money anyway you can think (driving a car, delivering food, charging a scooter overnight).

I just found out that a rental property I own is within 200 feet of a potential new site for a fast food restaurant.

Best bang for the buck Cuban food.

The worst problem you have is the trash collection will not pick up due to the appliances and will not get out of the truck to pick up everything that is stacked.  

I am an over the road truck driver now with no bills, so have literally listened to every podcast before doing this.

Research from the the University of Florida, Institute of Food and Agricultural Sciences Florida Medical Entomology Laboratory showed that biting midge populations were reduced in test areas of Vero Beach and Boynton Beach, FL, and Castaway Cay, Bahamas.

I would recommend looking for the BP podcast "Vaccuum the Truck". 

Stores ran out of food and gas stations ran out of gas.

There is definitely money to made in SS, and plenty of people are doing it.I'll also add to Mike's comments that small increases are easily attainable as (1) tenants typically aren't talking to each other about price (i.e. comparing their rent), etc and (2) most tenants don't find a small increase in price motivation enough to spend money on a moving truck and spend a weekend or more moving their belongings to a new facility.

Another food for thought is that if you do your own work and something goes wrong, your insurance might not cover it.
