ITC Refund of GST on rent paid for Day trading business

Hi

I am doing share trading(Day trading ) with my own capital. I have rented a place for which I pay Rs 12000 as rent every month. My landlord has notified me that I will have to pay GST of 18% on the rent. Is it possible for me to claim Refund on the GST I paid. I aint offering any services to anyone. Just trading with my own capital

If yes, how much refund would I get and how long it would take for me to receive the refund to my bank account. If no, is there any other alternative for me to pay rent and lower my cash outflow due to rent?

Thank you
