Sector 152: The real costs after possession

Sector 152, Greater Noida — something about its green tag doesn't quite add up. Builders yahan par kaafi high quote kar rahe hain, especially for 3BHKs. I'm seeing prices around ₹1.2 Cr, but honestly, what's the real ground reality? As someone jo market mein hai, I know these rates sometimes include hidden charges. Kya yahan maintenance charges bhi bahut high hain? Aur koi other unexpected costs jo log face karte hain after possession?
