What they don't tell you about Delhi property costs

Possession mili last month, Jhilmil Colony mein, CGHS Group se. Socha tha total cost clear hai. But bhai, hidden charges ne toh budget hila diya. Maintenance advance, society formation fee, car parking ke extra paise... ₹2.2 Cr ka 3BHK ₹2.35 Cr tak pahunch gaya. Ye all-in cost pe sabko surprise milta hai kya? How to avoid these later shocks?
