The reasoning behind this: water usage is pretty much going to be an average amount per person, regardless of unit size, whereas with electricity, a larger unit typically uses more electricity: more outlets, gadgets, lighting, heat/air.

Look at roofs, siding, plumbing, drainage, electrical boxes, wiring, duct work, heating and cooling units, water heaters, and windows.

They also insist on adding in the cost of heat despite the tenants paying for that. 

I assumed they meant the heat was out, but when I asked what was wrong with it, they told me "I set it to 60, but it's only 70 inside...".

I was discussing rent and property situation with my tenants, and they got pretty heated and threaten me with legal jargons.

I want to get this fixed, as I'm sure it's driving up my tenants heating bills and could lead to increased vacancy in the future if they're too high. 

That meant our units had air conditioning and individually controllable heat and the tenants were paying for the utilities!

The people you rent to will be more so classified as "Lodgers." in a co-living situation.The Rental license is not "strictly enforced" right now but new laws are in place and enforcement will start heating up. 

Pet hair will make its way into the crevices of the homes appliances and heating systems.

When we receive a work order it's always classified as non-emergency, Urgent, or Emergency.Calls first go to our U.S based call center who identifies potential emergencies such as leaks, no heat, clogs, etc.
