The documentary is called "Life off grid" and it's available on Amazon Video. I think you have to have Prime subscription for that . If you don't have that , maybe you can find it on youtube or something like that.
I looked at things from UP but the prices were exorbitant. I am not sure exactly where were you looking. Please send me a link so I can check it out. I found some parcels available for like 100 k, but that's not going to do it for me. I am not by any means loaded or anything but I would like to buy something and I need it to have the home already on property so that I would only have to add my touches, but buying a land for 100 k and then start building it would not pan out for me. I mean there is a way I could do that , but that's not the point. The point is I would still like internet and electricity , I would grow my own food etc. I am not a big fan of Wal Mart at all, I don't shop there, so I would have to find somewhere else to shop.
My boyfriend lives in NC currently and we go back and forth. I am in FL, but we always talk about how it would be if we were living remotely. And he says that if we are connected to the grid then we are not off the grid. I am telling him that if we are connected to the grid but we don't have neighbors and other modern conveniences , and we are in a cabin or somewhere like that , then it would be remotely. Yeah sure NC, TN would be good states to live remotely. I think in theory it sounds so good, and I would like to live a simpler life but I wonder how many of us could do it.

I would get used to it eventually, I would so embrace living off my own land and lead a much simpler life.There is too much drama in the world right now. Gives me anxiety.
I hope you enjoy the documentary. Let me know if you watch it.
Thank you for your response.
