I lived on a subsistence farm without any electricity until I was around 5. It is not as hard as many would believe but we did have the advantage of a well (also a free flowing spring not too far away) and lots of land.
Garbage is no problem, we simply dug a large pit far from the house and burned it regularly. An outhouse is not as bad as one would think either. The main problem is it is located a distance from the house.
Right now the main problem I would have is my house was constructed after central AC became common and would get really hot during the Summer.
Might I also suggest that it needs to be properly situated away from your water supply.
This is a point brought out in "Cottage Water Systems" by Max Burns. This guy is a little off-the-wall in some regards, but his advice about properly situating the components of the system made me realize that I needed to rethink my system out at the farm.
