I haven't found any "plug and play" meters for an already existing heating system - I imagine you'd need to monitor gas consumption, and each unit's thermostat would meter the valve.

I struggled in every aspect of learning wich was expected from a child who was raised In a bad situation mixed with alcoholism and domestic violence, but As i entered my third decade of life the world showed me just how brutal it can be. 

from a time consumption perspective?

I worked day and night going without sleep while maintaining an unhealthy consumption of energy drinks.

Top Ramin, spagettios, pasta, cereal, basically eat cheap, no deserts, no soda, alcohol, dinning out, etc... 

The tenant is a real piece of work - an alcoholic, a druggie, and a total liar.

Alcohol and drugs involved too of course.

I would not have squandered my money on women alcohol and tobacco and anything else I could buy .

Alcohol has an inverse relationship with the economy.

Once consumption is in line, you are open to rent reduction.
