If you have a written lease, you're entitled to receive rent for the lease. However, if there is no written lease, any lease would be based on what you agreed to orally. But, oral contracts are only good for 12 months. Thus, an oral agreement cannot be renewed automatically unless you make new oral agreements year to year.
Therefore, if you never entered into a lease for the years you're talking about, he doesn't owe you any rent.
