The Jewar Airport hype feels like it's peaked, not still growing.

I'm looking to upgrade to a 3BHK in Greater Noida for my family, kids' school admission is a big factor. My budget is around ₹1.5 Cr, maybe a bit more for the right place. Honestly, I'm confused if it's still a good time to buy, or if prices have already factored in all the Jewar and FNG Expressway benefits. Should I look at ready-to-move in Sector 150 or Noida Extension, or maybe something under construction with Godrej or ATS? My wife's priority is safety and good schools nearby. Is 2026-27 too late to see good appreciation? What's the real ground reality for appreciation and rental yields there?
