Speculation on land ownership when the Complete Redemption arrives is a wonderful waste of time.
I am not a real estate expert. However, my house in the Shomron belongs to me. I can sell it and receive market value. Thousands have done this and it is routine. I have a 49 year land lease from the Zionist State of Israel, and it will most likely be renewed for another 49, and then for another 49, etc… But it and the land underneath are still mine.
What the OP seems to want is a shtickel piece of land for the purpose of keeping shmittah or simply owning “karka b’eretz yisrael”. If that is so, it is very commendable. It is at least a partial acknowledgement of the pasuk וירישתם אותה וישבתם בה. A nice gesture indeed, and a step in the right direction. Akin to owning a Shas but never opening it. At least if I have it, there is a chance I may one day open it.
