Rental agreement expired

I have rented out flat in 1/1/2016 and entered into agreement for 3 years.. on expiry of 3 years we asked tenant to renew agreement he said " he is exploring opportunities outside India and he also appeared for few interviews so we will enter into agreement if nothing works out and he also assured that before leaving he will give atleast 2 months notice". After 6-7 months I asked for rental agreement he again mentioned the same thing..as he stayed in our flat for almost 3.5 years so I trusted his words. In 2020 we couldn't enter into agreement due to covid 19. Not when I asked him again for agreement in Jan he said ok and next month he gave me notice of leaving the premise in 1 month. In last 2 years we asked us to repair couple of items like bathroom floor tiles, doors and gyser etc.. So now I have 2 questions 1) can we recover 2 months rent as he was not willing to enter into agreement and he gave assurance 2) I read somewhere that after expiry of rental agreement if anything breaks down then tenant needs to pay double, is it so?
