Renting is over, but Panchsheel Green has me worried.

Visited Panchsheel Green last month, thinking I'm finally done with renting. My landlord raised rent again, yaar, had enough. Finally taking the plunge, but talking to some residents there, I heard about these crazy high maintenance charges. Builder ne brochure mein kuch aur bola tha, aur ab RWA itna charge kar raha hai, it's insane. Matlab, services bhi proper nahi mil rahi, power backup bhi intermittent hai. Log bol rahe hain bahut hidden costs bhi hain jo possession ke time pata chalte hain, not just maintenance. Is this normal for Greater Noida projects? Especially in Panchsheel Green? Anyone else facing this issue? What did you guys do? I'm honestly not sure if it's worth the EMI vs rent math if these hidden costs keep popping up.
