as someone else said, it looks like rezoning and that might be hard in many other place. For instance in France, you could be per-empted until late in the process by the SAFER, the entities managing agricultural land. They might buy it from the vendor at market price when you try to buy the land, and sell it for another price they see fit to a farmer of their choice.

Not as frustrating as what OP described. Still. Simple Administrative formality can fuck up your plan badly.

CF a fine piece of self reflection on our own adminstration. ( I love our admin, it's a fine piece of Napoleonic technology. But. yah. ) https://youtu.be/JtEkUmYecnk?t=34
