It depends. If you own a single block dwelling and have a yard with trees, plants, lawns or a pool there are always things to do.

$500/year for the garden is very conservative, even when you're doing all the labour.

It would be more like $500/month were you to get a gardener in. If you need an arborist (for example cutting back tall trees close to power lines or encroaching on neighbours) it gets expensive very fast.

A pool also costs at least $500/year just in chemicals.
