I've been reading a lot of the homesteaders books, and the investment that you put into it, solar power for keeping your electric/well, etc going, butchering materials, processing stuff... all of it takes money invested, i doubt you'd ever break even. At least not for a long time.
Granted, you could do it fairly barbarically, like people did 200 years ago, but they also used to get sick from infections and all sorts of other complications.
If you're going to do things right, it's gonna cost money, especially if you're humane to everyone and everything involved.
