I've done it at the edge of a small town (~12k inhabitants). My grandparents' home was sitting uninhabited for a few years and it once had a beautiful vineyard, a big orchard, and generally a wonderful view. At the edge of a forest.
I've always wanted to live close to nature. I was burned out with my corporate programming job, and I was dreaming of starting out some life-style businesses/SaaS/ something of that sort. I already had some investments that allowed me to live there without financial stress (i.e. the passive income more than 2x covered my living costs).
I was within walking distance of grocery stores, ~1-2km from downtown.
Did it work? Hell no. The biggest issue was I think that I was single, knew nobody in the area, and basically the time spent with just maintaining the house and the surroundings would take more than half of my energy and time.
5 months out of 12 I had to take care of the fire for heating. The whole garden and vineyard were invaded (still are) by a few species of trees such as black locust, that were growing faster than I could cut them, but also oak, birch, basswood and so on. I had a chainsaw and still couldn't keep up. Even after I had a big stack of dried firewood, I still had to spend 40 minutes every morning with actually setting up the fire in the woodstove and so on. And then the snowfall. It was not like in my grandparents' time, when they occasionally had 50-80cm of snowfall, but if I didn't want to be completely stuck there, I had to shovel a lot. The house was about 3 flights of stairs and about 10 more meters away from the street, so it was a bit of work.
Doing the groceries, while not that far away, less than 2km, the return trip usually meant about 150m of ascending. I didn't use a car at the time, so it was a bit tiring. Cooking also takes a big portion of your time.
Then the house itself. I had to do a lot of repairs as the house had been uninhabited for a few years, after my grandparents passed away. The roof. Humidity problems. I had to do some concrete underfloor, that meant carrying tons of sand and bags of ciment uphill, again really hard tasks.
The house had electricity from the grid, and while all the other amenities were available, I chose not to connect to them. I was using water from a well.
In late summer, autumn, I was picking fruit, making jam, also spending a lot of time with that. I tried my hand with organic agriculture, planted vegetables such as tomatoes, potatoes. But then I had issues with wild boars that would come and ransack a lot of it.
I spent about slightly less than an year there, all in all. Did I accomplish much of my main goal (that is business-wise)? Not really. It was a nice experience that maybe I'll repeat some day, but probably only with a partner so that we can split some tasks, and not be almost completely isolated.
Going there for the purpose of having a really low cost standard of living so that I could focus on my priorities didn't really work, because I had to spend a majority of my time just to live there. I could have invested money to make it easier. There were a lot of things that simply made living there harder than it should have been and could be fixed with some investments. I decided that I would be better off in a bigger city at this point in my life.
