Least: We live in the middle of nowhere. There are nothing but farms around us, low population, no traffic. Nothing.
These things are great when you want to be able to let the kids out to run around & play in the yard. They can strip naked & play with the hose, scream, yell, and have plenty of space to do whatever they want with no neighbors to disturb. I don't have to keep my lawn mowed unless I feel like it. I can paint my house any color I please & if I want to leave a well worn statue of the Muses on my roof for 6 years there is no one to complain about it but the cows. Sound does carry so I can't host a rock band nightly, but apart from that my restrictions are few & far between.
These things are not so great when you need milk, or your kids would like to play with someone other than themselves, or when they want to do something besides play in the yard, or you want a cup of coffee or to show for a new pair of pants. The absolute closest place to buy milk is 10 miles away. Any kid related activity is at least 20, ditto for shopping.
Ideally we want to own 40 wooded acres with a 2 mile long driveway that ends across the street from a shopping mall with a grocery store, coffee shop, B&N and a Target. All the seclusion and easy access as well. :)
