I am now getting vexed with this new tenant who has been complaining about one thing or the other.Today she saw a bandicoot in the backyard and called me immediately saying she found a 'weird' animal in the backyard.Their complaint seems like an indirect way to push me in to cleaning up the backyard.The backyard is not part of their lease and is offered as a freebie and I have no control over to the lush vegetation in my tenants backyard that overflows into mine.Should I ask them to terminate the lease and leave if they don't like the place?

A charming horseshoe driveway, chain link fence enclosing the entire 10 acres property line, two additional fenced in back yards, covered back porch and a fenced-in gopher proof vegetable garden.

For example, a spike in water usage could be from a leak in the plumbing system, maintaining landscaping during a dry spell, keeping a vegetable garden, washing vehicles on the property, or doing other peoples laundry. 

California farms produce a third of American's vegetables and two thirds of America's fruit (source: https://www.cdfa.ca.gov/statistics/).Now let me ask you a question: what do you think the racial makeup of California farm workers is?

The property was so overgrown with vegetation, we had 6 huge dumpsters filled before we could even start work on the home!

As you’ve seen this weekend, high temperatures also increase our wildfire risk, in part, because the dry vegetation has dangerously low moisture levels.

In the inspection I don’t see any mention of the 20 sandbags near the foundation but the inspector did have one line stating “marginal- vegetation need to be cut back away from the house as they may damage the side” and “acceptable- drainage”When I looked back at the disclosure I see where the previous owners have repaired moisture damage in the past by a company called biosweep.

Installed landscaping; fish pond with pump, fountain, trees, shrubs, flowers, retaining walls, stone patios, paved walkways, vegetable garden.

just looked at @Erik Hitzelberger link... that's what I have :)I use it for soaker hoses on my vegetable garden

From google maps and the pic my wife took, there seems to be some differed maintenance i.e. exterior paint and slightly over grown vegetation.
