Indeed, the entire monetary system of debt consumption is designed with you being the slave.

While sub-metering may have been the "right" thing to do, it was not the right business decision in that instance.As previously stated, I am in agreement that holding everyone accountable for their resource consumption is they way things should work.  

We've never had a machine fail inside the 5-year window, unless it failed in the first 6-months due to a manufacturing defect ... in which case it is covered under warranty (which is 24 months on the units we purchased).In short, the extra rent and the ease of filling units (before the become vacant) more than offsets any increase in water consumption.

The same diet also inputs 7,900 BTUs of energy into the human body through food consumption.

At times when your system is producing less than your consumption, your meter will spin forward.

You might still be stuck with only a single water meter, and have to build that into the rent (and in CA water is probably at a ridiculously high price) - but tenants can actually start to conserve when they see savings, and separation of meters gives them visibility to their consumption. 

I have a 2 family that all the utilities have been sub metered so each tenant can be billed based on their individual consumption.

An energy auditor from the electric company could also enlighten her on consumption if they do free consults in your area.

I also want the inspector to tell me multiple things like "is the roof suitable for rain water collection for human or animal consumption or both" and needs to know to check for how the metal seams were done, any nails used, etc and I suspect only an ag type inspector would know these things… There is also some ag machinery that I may need to get appraisals on because I know nothing about pricing tractors or implements or such (my wife & I grew up farming but didn't ever buy anything because our parents did all that).Another example is that I can pursue the home loan through my banks but I will need to talk to the local farming property loan people and don't know much about that...

@Steven JeffersonGas tankless wh have more BTU/hr consumption compared to a regular 40 gallon Wh.
