Hyderabad property deals: am I missing the real negotiation?

Did a site visit to Salarpuria Sattva's project near Saroornagar last weekend. I'm currently in a 2BHK but thinking of upgrading to a 3BHK or villa, budget around ₹1.5 Cr. Everyone talks about negotiating hard. But honestly, can you really knock off more than 2-3% on new projects in Hyderabad? Builders seem super rigid, especially in these hot areas. Is it just a myth, or am I doing it wrong? And pre-launch pricing? It feels like they just inflate the initial price to show a 'discount' later. Is early bird actually a discount for real investors, or just marketing fluff? I'm trying to maximise ROI here, not just pay less than the next guy. Change my mind.
