Finding undervalued pockets near Noida Extension infra

Honestly, I'm fed up of renting; landlord hiked rent again, so I'm finally taking the plunge in Noida Extension. I've been researching investment windows, especially how upcoming infrastructure like the Aqua Line extensions and FNG Expressway will impact prices. Properties around Sector 106, like 2BHKs for ₹70-80L, seem relatively affordable. Is this still a good entry point, or has the market already priced in future growth? My main concern is the timeline. Are promised completion dates for the metro and FNG realistic? Or should I expect delays impacting appreciation? I'm trying to figure if investing closer to these future corridors now, or further out, offers more potential once infra is live. Just making the EMI vs rent math work. Any advice on identifying undervalued pockets before they get too hyped? Hope this helps someone.
