Working in real estate, now buying for myself — it's different

Okay, I'll be honest, working in real estate doesn't make buying for myself any easier, especially with the 'Gated Community' corridor in Gurugram. I know the builder spiel inside out, but seeing it as an end-user, not a channel partner, is different. The appreciation here has been crazy. My gut says it's peaked, but then I see new launches in Sectors 82-84 still flying off the shelves. Is there still genuine upside for a 2BHK or 3BHK here, or are we just buying into FOMO now? I'm talking about actual ROI, not just paper gains. What are the hidden costs or negotiation hacks folks have found useful in this specific area? I'm trying to cut through the marketing noise for my own purchase. Any tips on checking the real OC status or PLC charges that builders conveniently gloss over? Hope this helps someone else too.
