SS Group Chakkarpur: Real all-in cost kitna hota hai?

₹1.8 Cr for a 3BHK in Chakkarpur, SS Group ka project – I thought I had a handle on the costs. I work in real estate, but buying for myself, it's a whole different game, yaar. Builder quote mein toh base price aur basic PLC hi dikhta hai. But then registration, stamp duty, parking, electricity connection charges… sab add karte jao. Initially they said around ₹1.8 Cr but after adding everything, it's closer to ₹2.1 Cr. Matlab, 15-20% extra easily. Aur hidden charges ka kya scene hai? Possession ke time pe maintenance deposit, club membership, IFMS... yeh sab toh batate hi nahi properly. Builders ka toh alag hi math hota hai. Has anyone faced such a huge gap between quoted price and actual all-in cost in Gurgaon? Kya yeh normal hai Chakkarpur mein bhi?
