A tenant refuses rent increase and payment term changes: What to do?

Dear Sir/Madam,

I purchased a property in December 2022 and served the eviction notice on January 9, 2023. The current tenancy agreement is set to expire on June 30, 2023.

I want to modify the payment terms for the new contract, effective from July 1, 2023, to January 8, 2024 (the end of the eviction notice), changing from 12 checks to 1 for the six-month period.

Additionally, I intend to increase the rent by 20% as I believe the existing tenant is paying 60% less than the current market rate.

The tenant refuses to accept these changes and wishes to renew the lease with no alterations.

Where do I stand in this situation?
