J Block prices: justified for a 2BHK?

Been renting for ages, this landlord hike was the last straw, tbh. Finally thinking of buying a 2BHK in J Block, Greater Noida, budget ₹75-80L. Prices yahan ke kaafi high lag rahe hain for a 2BHK. Is it really justified, ya negotiation possible hai? Also, metro connectivity kaisi hai for daily office commute? Aur water supply ka kya scene hai, especially summers mein? Any hidden issues ya maintenance charges kaafi zyada hain? Kya lagta hai, should I commit to J Block?
