My 2 cents, land ownership is highly over-rated. Having access to land and being able to pull
profit from land does not necessarily imply land ownership. If you start with this insight, you won't waste valuable time and headaches fretting over the fact that you don't own land. Even Salatin rents. I have arranged 4 pieces of land of varying size from 40 meters square to 2.5 acres that are not mine but depend on me for managing and I can pull product from them without giving back anything to the legal owners. People just give me land left and right, as long as they can maintain ownership.
As Alder Burns notes, if I were to own that land outright, I would be in debt and have no money to do any of the managing.
There is the PermaEthos model now up and running, and there is the small urban plot market
gardening model (SPIN) where ownership is really secondary.
Tractors are another also unnecessary. Hightly useful, but not mandatory. Seed costs. I spend 200-500 euros a year for seed, but it goes down as long as you're spending on perennials, reseeding annuals, and growing your own plants. If you run animals, you shouldn't need to invest in seed much. A trackhoe is a good investment, but if you're lucky you have a friend in the construction industry (get one of those!) who can lift earth on a saturday morning for next to nothing. Right now seeds, plants and
chickens and random infrastructure are my main expenses. I'm building my second
greenhouse and this one is costing even less than the first and it's of higher quality.
The best insight: get family and good friends in your corner. In the long run, they will be your best cost-mitigating element.
