From broker to buyer – my Delhi investment hunt

₹1.8 Cr for a 3BHK in Bhagwati Garden Extension with Express Builders – that's what they're quoting. I work in real estate, but buying my own investment property in Delhi feels like a whole different ballgame. I've seen the market in areas like Vasant Kunj and Greater Kailash, prices are just insane. Honestly, I'm trying to figure out how much real negotiation room there is. Builders always say 'fixed price', but off the record, you know there's some wiggle room, right? What's a realistic percentage to push for on new properties, especially for an investor looking at the total cost of acquisition? Also, what hidden charges typically pop up closer to possession? PLC, parking, stamp duty are obvious, but anything else to watch out for? Not sure if construction-linked plans are smarter than a larger down payment for ROI...
