DH and I are looking for new land, right now we have 45 acres, we don't use most of it, we have a 700 yard shooting range that we use 2-3 times a month, and we have a horse, but she is on less than 1 acre of it right now due to the cost of fencing. When we started looking for new land I thought I wanted at least 40 acres again BUT we are having a hell of a time finding that much land in our price range that is better than where we are now. We want to build an earth ship house, and have a small farm that can sustain us, a few goats, some chickens and rabbits, horses and a family of cows for meat and milk. We also want it to be closer to the mountains than we are now, and hopefully have trees and some sort of access to water or the ability to drill a well. How much land do you think is necessary for this? we know that even if we had 100 acres we are still going to have to buy hay to feed the livestock, so I am not thinking I will ever be self sufficient enough to not have to buy animal feed.
I don't know if this will matter in your decision but it will be my family of 4 (I would like to have more children but DH says no), our best friend who is a single older man (in his 50's, he is paying for most of the land), and possibly another family of 4 will come with us. And when my Father in Law and Grandmother in Law die, my Mother in Law will be coming to live with us also. So we will have somewhere between 5 -10 people living there eventually. So we will eventually have at least 4 horses, 3 cows, and enough rabbits and chickens to feed us all on a regular basis, not sure how many goats we will actually have in the end, but I would think 1 or 2 for milking and a male to breed them, and then we would eat the offspring.
