So far I have purchased 10 acres of land 45 miles outside of a city and 13 miles from a small town with all the amenities I need. My plan is to go as /r/OffGrid as I can.

For electricity, I am installing solar/battery system and a backup propane generator. My refrigerator will also be propane initially but if my solar works out well enough I might change that.

For water, I have a small creek where I am installing a Ram Pump. Upstream is all timber company property and I have confirmed that they don't use any herbicides or pesticides so I am pretty comfortable with it as far as not having chemical contamination. I use a Berkey Water filter to take care of any biological contamination. I will also be putting in a small rainwater catchment system for redundancy.

For transport, right now I use my electric bike for most of my trips and I think I can make that my sole mode of transport that I own once the kids are moved out and I am out of the city fully. The nearby town does have car/truck rentals for about $30 a day if I really need it but the county also has fare free transit services, including dial-a-ride service so I am hopeful that I can be completely car free. USPS/UPS/FedEx all service the area I am in so I can get most items I need delivered.

For shelter, the county allows you to live in /r/yurts full time without any permits, and as long as the yurt deck is less than 30 inches above grade, you don't need any building permit. They also allow for composting toilets so I do not need any sort of septic system. I will have a wood stove for heating and cooking (with a propane backup).

For food, I've been gardening for years and also have been keeping chickens and bees for almost as long. I would probably add rabbits in to the mix so I hope to be able to grow at least 75% of my food. In addition to putting a bunch of fruit trees, I also have lots of maple trees so I am planning on trying my hand at maple syrup and growing mushrooms on logs. I'll be buying oatmeal, rice, beans, and some other staples so I am hoping to keep food/animal feed costs to about $100 per month.

For internet, I am going to rely on an unlimited data plan on my phone. I used CellMapper to locate the nearest cell tower (turned out to be about 4 miles away) for my carrier and saw what bands they broadcast from that tower. I used caltopo.com to figure out the compass bearing to the tower and aimed a cellular booster with a directional antenna that works with those bands at that tower. I went from no cellular connection to three bars of LTE. The county also offers free wifi at several sites around the county and the library has great free internet also.

For healthcare, I live in a Medicaid expansion state, so as long as that does not go away, then as long as I make under 133% of the poverty level, then I can get free healthcare. If I end up making more than that, I will still be eligible for subsidized medical coverage through the ACA.

I expect my initial setup cost to be around $100k and my ongoing estimated costs are $500/mo or $6000/year. So once I am all set up, I can get by on having a $150k nest egg but I am aiming for closer to $250k just to have wiggle room.
