Not sure if watering helps or hurts, but your tenants are not going to water.Is everything separately metered?   

I then but a Tiny Home on it and set up my PV system and water catchment and lived there off the grid for 4 years.

The things that draw power are water heaters, and appliance.

Sorry, but I need to tell one more short story.I have a 24-unit apartment building and I had one tenant who had moisture on his windows every day where it looked like he sprayed the window with water from the inside.

Some things you can negotiate such as you wanted to put in a new water heater on the day they have a birthday party planned. 

Built into televisions, laptops, Alexa, Google and Apple devices, not to mention a slew of "spy" cameras designed to look like ordinary household items (water bottles, phone chargers, clocks, smoke detectors, shower heads, and even teddy bears).

The water heater had a little corrosion, which I saw (and frankly means it needs to be replaced) and he said one previous inspector noticed a little condensation in the electric panel.

Also got to go and deal with an air conditioning issue at my other property, Shop vacuuming up water and cleaning up a basement floor!

Water management is another huge issue - wells, septics, sump pumps - didn't really know anything about these, but have gotten an expensive crash course! 

@Joshua TanWe have access to a Landlord insurance program that includes 2500 deductible, 1 million liability, replacement cost, loss of rents, and water back up that is very competitive in price.
