Yes, we have. We did this 10 years ago. We moved from Santa Barbara,CA to northern Arkansas and bought a 5 acre piece of land with a 2-story farm house, on a 3 mile dirt road, on the edge of Buffalo River National Park, very peacefull, very pretty, very "remote". We wanted to create an off-the-grid life by growing our own food (my wife focuses on the animals, I focus on veggies and fruits) and use open source technologies to assist at this if it made sense. My wife started a local and resonable successfull business (today), while I would do what I do, remotely. I'm a back-end developer, focused on LAMP stack technologies, trying to go from employee to freelancer to ultimately, a international software business (Isn't that what we all want?). I loved my 15 second commute.
Most things went well as planned, but it was hard work. Days start at 5AM (it gets hot here) and end at 9PM, 7 days a week. Upkeep and repairs took most of the time and resources. Lessons were learned, mostly the hard way. But we made progress and our place is now our Home.
Still, internet sucks (DSL), power losses several times a year, sometimes for half a day or more. We're still not off the grid (except for my greenhouse), but that's not on my todo list anymore. I have bigger fish to fry.
Of course, setbacks had to happen .. about a year ago I was part of a company-wide layoff. Initially, I wasn't too upset .. the house needed a new coat of paint and I needed to update some skills, as I want to work on back-end automation (Jenkins, Ansible, Chef, NodeJS, Docker, cloud tools and what not) and focus less app development, so I took time off and focused on what I wanted to do, according to my yearly plan. A few months later, the house was painted, the courses were finished and I was re-charged to get back into back-end work again. .. i n m y d r e a m s .. Long story short, it took me 8 months to get into a new position and I took what came along first, a full stack web developer position, 2-hours drive (twice a day) from where I live at a payrate I had 10 years ago. Now, all I do is work, sleep and drive. My weekends are packed with chores to upkeep our home. During my job search time, my wife worked more IN her business (to increase our income) as opposed to working ON her business.
We had to get rid of 80% of our life stock, simply because neither one of us was home long enuf to take care of them. My greenhouse ended up empty. I'm still looking for a remote position, but they get sparser by the minute.
I didn't get a single inquiry where telecommuting was an option. We're glad we had an emergency fund that covered our bills for about a year. It's close to depletion now.
We both love our home a lot, enuf to not sell it anytime soon, but living remote and working remote come at a price. I never was really concerned about losing my job when we moved here. "Jobs are everywhere", I thought. True, but that don't mean you can get one of them, even with +15 years of experience and an updated education with skills much wanted. That was definitely new to me. I've been 'in between' jobs and contracts before, but this time it was different.
My advice on moving to the countryside .. have a plan B and resources to cover for it.
