Tenant's rights in case the landlord wants to sell the apartment

Dear Sirs

I will appreciate your kind advice regarding my case.

I am renting from the landlord since 3 years now, all payments are done on time and even I am doing maintenance for things in my house which I am not supposed to do but to maintain the property in good shape out of goodwill.

I received an email from my landlord asking for renewal as per the agreement, 3 months prior to the termination of my current contract. I visited them and handed over the new cheques for the new rental year in advance and signed the new tenancy contract.

Now I discovered that he may be selling the property and may not renew my contract despite receiving my cheques and delaying EJARI renewal. I still have 2 months to go in the current contract.

my question to you is, are they allowed to renew or to compensate if they already took my cheques for the new year rental and exchange of emails with the same is available?

What are my legal rights here?

Thanks and have a great day.
