(Wonder what happened to that poster? There is a suitable property on the market now... at a cool 4.5 million.)
Also, use the search term 'BGBB' - there are a couple dozen EF threads that reference this piece of legislation that you will soon need to delve into.
The text of the Bundesgesetz über das bäuerliche Bodenrecht is here:
https://www.admin.ch/opc/de/classifi...253/index.html
In short, the sale of farmland is heavily restricted, as is it's use. If a property is held under the BGBB, unless you are Swiss from a farming family going back to 1291 there are significant, if not insurmountable, barriers.
Are you CH/ EU as well as American? Do you come from farming families or have you owned or worked farms yourself?
As Americans we at a minimum would need a special permit granted by the Farming Gods, and in practice in the cantons we have investigated (SZ, LU, SG, UR, ZG) no way, no how.
This despite OH having grown up on a farm, with the knowledge and hands-on experience needed. He's a Hoosier farm boy at heart, he'd be running a working hobby-scale farm, he wouldn't be a weekend gentleman-farmer merely playing at the welly-wearing lifestyle. (The latter is part of what the BGBB is in place to prevent.) Despite having the resources to do it right, we would not need nor want the usual subsidies, despite the fact that we love country life, would have truly poured our hearts into the farming community - a big fat 'nope'.
We have been told point blank that as non-EU people we have no chance to buy BGBB land. (And frankly, our age was an issue.) Is that really the case? Who knows. You might have a different experience than we did - I certainly hope so.
(Also, I have no idea how other cantons put the legislation into practice. Could be a radically different approach... Anyone from the Romandie or Tessin care to comment?)
Another option is Landwirtschaftsland that has been taken out of the BGBB. This, too, might require permits to purchase - much depends on the individual property. Certainly development of Landwirtschaftsland is strictly regulated - my rule, from experience, is only buy if we would love the property exactly as it is with no changes - because when the whole alphabet soup of governing agencies gets involved you might not have many options.
The expert in the sale of farm properties in the greater ZH area is Juckerberatung. Be aware, though, that their clients are the farmers selling.

When a farm property not under the BGBB came up in SZ about 10 years ago we went to the open house... along with what seemed like hundred other people! seriously - they had to hire security to direct traffic.
Another firm you might try is Immoleader:

The specialize in horse properties, but over the years I've seen some non-horse hobby farms as well.
Like Amogles says, if you are really looking for a hobby farm, Switzerland probably isn't the place given dearth of available properties and the barriers that are in place.

I spent over a decade chasing my farming dream. Didn't happen, and now it's too late. Hope you have better luck than we did...
Have fun browsing the BGBB.
All the best.
