Possession process mein hidden catches?

Just moved into Big Block South City 2 last month, aur possession process mein ek cheez notice ki. Builder ne OC ke liye bahut time liya. Agar pre-possession inspection sahi se karwa lo, minor issues identify ho jaate hain. Maintenance charges bhi clear nahi the pehle. Society ka vibe toh acha hai, kids ke liye parks sahi hain.
