In addition, the consumption of water by the machinery can be calculated and is usually indicated in the the design specs from the manufacturer.

I can tell you after many years owning ,managing long term sfr's one should count on at least 35% of gross rents for expenses, as newbies often neglect to factor in consumption of roofs,mechanicals, flooring, cabinets etc.

How do you know that the excess water consumption was due to excessive use of washer rather than other habits like extra-long showers, leaving the tap open in the kitchen the entire time while cooking, etc. 

The price of immediate consumption is much more visible than the price of neglecting long-term investment.

Thanks Is that kinda like an alcoholism halfway house type deal?

Found out later he was a dreadful alcoholic who lost his job, his car and sold his condo to live, thus the money he had invested.

Our raging alcoholic neighbor used to regularly and loudly berate us for parking there until he passed out around 10 am.

If so please private message me.Those are great options if you are doing the recovering alcoholic program.

We fixed the problem already and the city said the graph shows the tenant's consumption is back to normal.

As far as providing wines, I would say no, as you may run into recovering alcoholics, and I don't think that would change anyone's mind about renting.Most likely you have a local commodity and will have to price it correctly providing you have customers in the area who are looking to rent).Have you tried contacting the HR department at the hospital and getting their input on it?
