Bengaluru property negotiation is a myth

My lease ends in 4 months and I still haven't figured this out. Builders in Bengaluru are so opaque with pricing. Everyone glorifies buying, but nobody talks about the actual negotiation game. Prestige Group in Yelahanka quoted ₹1.3 Cr for a 2BHK, but I bet that's not the final price. Kitna negotiate kar sakte hain realistically? Matlab, 5% ya 10% bhi possible hai kya? Aur yeh hidden charges, like PLC, OC, maintenance deposit – they're just surprise attacks at possession. How do you factor them in from day one? Change my mind.
