Secondary market deals: Noida Extension's real discount?

Sector 46 — Tribeca Creators LLP ke project dekh raha tha. Noida Extension mein secondary market deals pe kitna negotiate kar sakte hain? New projects mein toh builders bolte hain no negotiation. Par resale mein kya actual discount milta hai ya bas time waste hota hai? Aur yeh floor-rise premium, PLC worth it hain kya? Meri budget ₹85L ke around hai 2BHK ke liye.
