I also just got told by the plumbing company that they suspected tenant tampering with toilet plumbing when they came to perform a consumption report.

I ran all the 240v electric to the hot tub & it's always set to 96degF with it being adjusted higher during use, yet the electrical consumption is not noticeable.We do not use anything other than Eco-one to treat the water, but I throw in a cup of chlorine after heavy use.

I cannot believe how financially irresponsible otherwise "professional" people can be when it comes to debt, credit cards, and over consumption.

Since 2008 we have consistently under-built for basic consumption.  

Tenant is responsible for paying for consumption beyond this and will be billed separately." 

I went for the SEER 16 models and not that it helps you so to speak, but the electrical consumption goes way down.https://www.duke-energy.com/home/products/smart-sa...

For example, our local natural gas company will provide therm consumption but not the dollar amount charged for each bill.

I still like dishwashers because it helps with the water consumption but low end units probably better without them.Low end units tend to get low end dishwashers so they don't have hard food disposers so they can't handle non-cleaned plates. 

As for the others I don't think most people who own 1,000+ units spend the majority of their income on consumption for themselves the majority is either reinvested or put towards causes that are important to that person in particular. 

While I am only human I have noticed direct correlation between the absence of sugar and high levels of motivation, energy, and daresay optimism; adversely I've noticed that high levels of sugar consumption, especially in daytime hours, lead to horrible crashes of energy, motivation, and daresay depression (not necessarily clinical depression but certainly depressed attitude or state of mind).
