Sector 127's ROI feels questionable right now.

The investment potential in Sector 127 feels a bit overhyped right now, tbh. I'm looking at a 3BHK there, around ₹1.1Cr, but worried about long-term ROI. Is the Jewar Airport effect already priced in, or can we expect more appreciation in 3-5 years? Also, what's the real ground reality for water supply? Are borewells common or is municipal water reliable? Not sure if specific builders like Godrej or ATS have better infrastructure in their projects there. Anyone have actual experience with this area's future growth or daily issues?
