Delhi property negotiation is mostly a myth

Is negotiating on property prices in New Delhi even possible anymore? Fed up of renting yaar, finally thinking of buying something in Patel Road. Shiv N Sai Builders pe kuch dekha hai. Log bolte hain Delhi mein discount ka zyada scope nahi. Kitna realistically expect kar sakte hain, especially for a 3BHK around ₹2Cr? Aur hidden charges ka kya scene hai? Don't want any surprises at possession.
