What builders don't want you to know about price drops in Greater Noida

Negotiating with builders in Greater Noida is a whole different ballgame for investors, I'm finding out. I'm so fed up of renting, landlord hiked rent again, so finally taking the plunge here. Been looking at 2BHKs around Noida Extension, maybe towards Khairpur Gurjar side for some space, eyeing projects like Maya Infratech. They quote one price, but honestly, how much can you *actually* get them to drop? For a ₹70-80L flat, is it possible to get more than 2-3% off, or is that just wishful thinking with the current market sentiment? Also, these construction-linked plans... are they really better for an investor focused on ROI than just a bigger down payment for a discount? Worried about project delays and paying EMI for nothing. Should I stick with a broker for better negotiation or go direct? Anyone with recent experience, what's your take on maximizing the deal value?
