Greater Noida mein undervalued deals kahan milengi?

Budget finalized, loan pre-approved – ab Greater Noida mein property dekh raha hoon. Sab jagah prices badh gaye hain, Jewar Airport ki wajah se. Investor perspective se, I'm trying to find underpriced assets, not just follow the crowd. Kya Noida Extension ya Yamuna Expressway ke kuch sectors mein abhi bhi real price correction possible hai? Ya phir Pari Chowk ya Knowledge Park mein bhi kuch hidden gems mil sakte hain jahan deal value maximize ho? My budget is around ₹90L-₹1.2Cr for a 2/3BHK. I heard sometimes builders like ATS ya Mahagun bhi achhe deals offer karte hain, away from the main rush. Any hacks to identify areas jo abhi tak overvalued nahi hue hain? Secondary market mein better negotiation scope hota hai kya?
