I just came to the conclusion awhile back that instantaneously drowning in money every month from my current income, while enjoying 2-3x the standard of living sounded a lot more appealing than being a 7 minute drive to Golden Gardens!

You can pick up a Stainless Steel ice in door fridge for $800-900 (Frigidaire 25.5cu) delivered and installed and used craigslist washer and dryer for $200-300.

Will you need to hire a gardener and how much will it cost?

Like I said, worry about tending their own gardens instead of worrying about how others are tending to theirs. 

When I rented out my main house (my wife and I are house hacking and living in our ADU), I overpriced the home and got applications and renting for full price plus a gardener fee.4.

I added a secured gate at the front of the property, created a garden for tenants, renovated the courtyard adding a fountain, and painted.

I don't know that the payback would be worth an indoor sauna.

Not having a dishwasher these days is like not having indoor plumbing.Based on your picture, it would look like hell anyway AND you'd have to find an 18" washer to fit in the space, unless you were pulling the cabinet by the stove too.

A simple message that lets them know there are lots of things they may need help with (gardeners, handymen, etc.) and endless questions that come up answered (what happens when...).

People you pay; your barber, gardener, bank teller etc.
