Kya Ghaziabad mein property negotiation real mein kaam karti hai?

Fed up of renting, finally looking to invest in Ghaziabad. SKA Group ke projects dekh raha hoon Neelmani Colony side. Kya pre-launch pricing mein real discount milta hai? Aur property price negotiation kitni possible hai? Builder bolte hain fixed price, but I'm thinking thoda toh kam hoga. Any investor experiences here?
