Is builder negotiation in Sohna just a myth?

Budget finalised, loan pre-approved – now stuck on how much I can actually save. Honestly, everyone talks about negotiating with builders in Sohna, but is it just a myth? I've been looking at projects around Southern Peripheral Road, even Adore RealTech, and they barely budge. Builders have these 'no-discount' policies, then offer some lame PLC waiver for a few days. My parents keep saying to push for 5-10% off, but ab samajh nahi aa raha. I'm thinking the real negotiation happens in the secondary market. Forget new launches; a distressed seller in a 2-3 year old project near Golf Course Extension Road probably gives better ROI for an investor. You can actually get a good 2BHK for around ₹1.2 Cr there, maybe even less if you're lucky. Trying to shave pennies off a ₹1.8 Cr new 2BHK feels pointless. Change my mind.
