That's great Greyhound, tenants with a lawn mowing business keep the grounds tidy!
Jess9, that's the way. See how you go.

In Auckland we almost always have tenants doing the lawns and small weeding.
Exceptions are generally when there are multiple dwellings on a smaller site, or the property has one dwelling on a large site ~1000m2.
Larger sites still, like lifestyle properties or farms are generally tenanted by people who can handle a large lawn so they take care of it. All as you would expect.

limegreen, I'm not surprised Dunedin flats would always include lawns!

Recently it's becoming more common for tenants to arrange lawn mowing contractors at their cost and we always recommend this if they are busy people and struggling to get around to it.
Most properties require annual hedge/tree trim which is at the owners expense.
