Landlord's threat to accept unfair rent increase or face eviction

Dear Lawyers,

I have been a tenant for the past three years and my landlord has been arguing about the rent. I have always stated that I will pay whatever is required according to RERA.

Last year, in January 2022, he gave me a court-attested notice to sell the property. Throughout the year, he has been threatening to evict me and not renew my contract if I do not agree to his demands of an 80% rent increase.

He has only had one viewing in the last 12 months (and has not listed the property on any websites) just to show that he is attempting to sell it.

He has openly stated that he is willing to allow me to stay if I accept the 80% increase in rent, but if not, he will ask me to leave (and refuses to put this offer in writing).

He claims that he has enough evidence to show that he tried to sell the property, and after I leave, he will leave it empty for two months before renting it out again, and there is nothing I can do about it.

Can I dispute this in RDC and get my contract renewed?

If I leave and he rents the property out after three months, can I claim damages from him?
