15 site visits, still confused about the real cost

₹2.2 Cr for a 3BHK in DLF Phase 3 seems okay, but final bill ki tension hai. Ganga Group ke pre-launch deals kitne genuine hote hain? My wife wants a bigger flat for kids. Possession par bohot hidden charges sunte hain – maintenance, PLC, OC – kitna extra lagta hai? Ready-to-move ya under-construction, kya lena chahiye?
