IS he not paying the rent ? Do you have any rent receipt or proof that he is in possession of the property as tenant otherwise he will claim ownership on the basis of adverse possession.

File notice of eviction.

Dear Sir,

You are suggested to first get the mutation done in your favour and then ask the tenant to go away for the reason that you need the residence for your own. 

if they stays there freely with nobody claiming to be the owner he will have a right. But if he is regularly paying the rent and there is a proof of the same the tenant cannot claim ownership rights. 

Possibility to get the property vacated from tenant as very very low and close to impossible due to period of tenancy and that top without any agreement. 

Yes, you can file an ejectment suit
