It depends on your definition of off-grid and community.
I live 3 miles from a town of under 1000 population in a county of around 5000 population on 160-ish acre farm. My closest neighbor is about a mile away. The closest large city is about an hour away.
We have Wind, Solar and Propane but are also grid tied to our Co-Op Electric. We are expanding the wind and solar as finances allow. We have wood heat if needed in the house and my shop is wood heat. We have two wells, both potable, both can be operated without electricity when needed. Both can be hand drawn, one has a hand pump and the other has an air pump system.
We have/raise Chickens(meat and eggs) and Goats(meat and milk). We have two gardens a small one close to the house and about 1 acre at the edge of one of our pastures. My Cousins raise cattle so we either buy or trade with them for beef. My cousins also do the farming on our property so we get cash rent from them for the farm ground and paid for the bales off the pastures that we don't use. I have a small wooded section at the north end of my property that I hunt every year...deer, turkey and pheasant are plentiful on our property so no problem filling our freezer. I trade/barter for other things as needed with my neighbors and family. As an example a few weeks ago I traded some gun repairs for a small hog from one of my neighbors that runs a large hog operation. Good for him because the hog he traded wasn't coming on well like it should have and good for me to have farm fresh pork that I know the source and quality.
My shop is behind the house, so work is a short walk away. Because I don't have to leave my place to work there are times when I go months without leaving the property.
While we don't live in an off-grid community, we do live a fairly separated life style with the ability to live off-grid if needed.
Depending on what you are looking for, you might look at buying a small farm outside a small town in the mid-west then spend the rest of your life getting to know your neighbors and participating in your community. It's a lot easier to have a say in a small community...Sheriff elections are decided by a few votes, County Commissioners are your actual neighbors. There are no city cops, the Sheriffs department covers the town patrols in our county. I know all of our Deputies, Volunteer Fire and Emt's by name and I know all of our postal workers by name.
In my case my family has owned this property since the 1860's(I still have the original homestead deed signed by whoever was signing President Grants name that day) so I am related to half the community but we don't shun outsiders we are just wary of them for the first few years...I suspect a lot of small mid-west communities are just like the one I live in.
If nothing else I hope I have given you something to consider.
