Infinitum Infratech: My hidden cost surprise

₹2.2 Cr for a 3BHK in Panchsheel Enclave — is this the new normal? I'm currently in a 2BHK and thinking of upgrading. Dekh raha hoon ki is price jump worth it for a 3BHK. Recently, Infinitum Infratech ka ek project dekha, unhone PLC aur EDC charges bilkul last mein bataye. Ye hidden costs kitna add kar dete hain total pe? Also, construction-linked payment plan pe negotiation ka scope zyada hota hai kya compared to a straight down payment discount? As an investor, total cost of acquisition kam kaise karein?
