My retired cousin lives on her large family property in Spain on the outskirts of a little village near Benidorm, in the high lands overlooking the sea but far enough that she does not have to deal with the hordes of northern tourists in the summer. She owns an old and simple 2-bedroom stone house sitting on several hectares of land producing everything from almonds to olives and nesperos and everything in between practically year-round, all organically-grown. Completely off-grid with full solar, plenty and almost free water for irrigation because her property is registered as a farm, very low land taxes. Overall, she spends under 200 euros a month on lodging. She has a few chicken for eggs, a couple of no-maintenance goats, she "rents" some land to neighbours in exchange for work on her property or useable goods: one hunts rabbits and birds and gives her some of his harvest, another produces honey and gives her more honey than she could ever use. Wine from the local coop is cheaper than water, and excellent (under 1 euro per litre). Fish and seafood and other necessities like bread and coffee and anything she does not produce herself can be purchased nearby for cheap. Between her husband and her, the average time spend daily to take care of the trees and garden is about 2 hours, sometimes much less, sometimes a bit more depending on the season.
I am tempted to move back there too, land is quite cheap, the area is beautiful and peaceful, but as a full-time nomad with only romantic ideas but no practical experience about growing anything, I'd get bored with this lifestyle very quickly. If you think this lifestyle suits you, go for it.
