Noida Extension is a black hole for your money

Working in real estate, I see everyone pushing Noida Extension. Honestly not sure why. It's cheap, sure, but the ROI feels glacial. I'm looking at Sector 37 instead, even if it means a smaller 2BHK. Everyone glorifies the 'affordable' tag of Noida Extension, but nobody talks about the endless construction dust and commute nightmares. Plus, resale values there are always lagging. Off the record, I think Sunshine Infrawell Pvt Ltd is overpromising in their Noida Extension projects. Is it worth sacrificing location for a few extra sqft? My budget is around 80L. Am I crazy to avoid Extension? Change my mind. What am I missing? Disagree? Tell me why. I want honest opinions, not builder sales pitches.
