I appreciate all the input I am getting, and Scunner a warm greeting from Al ain, as you know we have mild beautiful weather at the moment.
I will hardly call ownership of a small olive grove (max 10000 sqm.) a business, I was thinking just of having it and have a local farmer share the produce 50/50 or what ever the percentage while taking care of the trees and land. That type of sharing is done else where. At the same time willing to pay what ever tax they ask for of any profit of any sort, but without the hassle of establishing a business. May be one can call renting own flat a business if someone does that, but a small plot with trees is far from that.
I have tried to read as much as I could but I am running into a condition where it is stated that you have to present to the authorities a plan or project for the plot you buy, but then I am thinking if the plot is already filled with trees then what kind of a project are they talking about? I don't understand this part.
