Noida Ext builders: Hidden charges are the real EMI

Been paying rent for 7 years now, landlord ne phir badha diya. Finally taking the plunge for a 2BHK in Noida Ext, budget ₹70L tak. Godrej aur ATS ka delivery track record kaisa hai? Suna hai Gaursons aur ACE mein hidden charges bahut hote hain. PLC, IDC ke naam pe kitna extra maang lete hain? M3M ya Mahagun mein bhi aisa hua hai kisi ke saath?
