My Mohali 3BHK hunt: Hidden charges are insane.

Was supposed to decide by last month but Mohali mein property search bohot confusing hai. Dekh raha hoon Sector 29 mein ek 3BHK, maybe The Uppal Group ka. Initial price ₹1.8 Cr dikhate hain, but then yeh saare hidden charges aa jaate hain. PLC, parking, maintenance deposit, electricity connection... yeh sab milake budget bigaad dete hain. Seriously, all-in cost estimate toh kuch aur hi hota hai. Is it possible to negotiate these charges down, ya yeh fix hote hain? Kitna margin hota hai builders ke paas? Koi batao yaar.
