As reply to the above GEANNA BELL question a tenant cannot have any right title on the land. In a recent Supreme Court's judgement which came for appeal in the supreme court belonging from the State of Goa, between two private parties, it is specifically held that a caretaker/Chowikadar etc. cannot claim title in the land how long they stay on it. But you have to prove that he is tenant.
But they have the first right to buy it at the marketable price in case you sell it, they cannot force you to sell at a lower price.
