Do you pay for your house over and over again? No. That was my point. You also do NOT pay for your land. You pay TAX. If you paid $600,000 for a piece of land, where your house is, do you pay same amount again? Nope. Land IS mine, because I can do whatever I want on this land. Try to modify ANYTHING you lease. Fat chance.
The land is yours until the govt step in with eminent domain.
