Hidden costs nobody mentions in Noida Extension

₹85 lakh for a 2BHK in Sector 16B — is this actually the going rate now? Fed up of renting, finally looking to buy. Swastik Developers ka ek project pasand aaya hai. But total cost kya padega? Property price ke alawa stamp duty, registration, PLC, parking, yeh sab add karke kitna jayega? Aur possession ke time hidden charges bhi hote hain kya? Suna hai kuch extra costs aate hain. Kisi ne negotiate kiya hai yahan? Kitna discount expect kar sakte hain as an investor?
