Ghaziabad home buying: What's the real total damage?

I'm so over paying rent, Ghaziabad is my next move. Landlord ne phir rent badha diya, ab bas. Dekh raha hoon properties in Indirapuram aur Hindan Residential Area, maybe even Pragati Group projects. Base price toh dikh jaata hai, but yaar, yeh final 'all-in cost' kitna hota hai? Log bolte hain bahut hidden charges hote hain. Mujhe samajh nahi aa raha stamp duty, registration, PLC, parking, yeh sab milake kitna extra ho jaata hai. Is it like 10-15% extra on the quoted price? Ya aur zyada? For a 2BHK around ₹70L, what's the actual final figure I should expect? Interiors ka bhi budget rakhna padega. Any tips to avoid last-minute shocks with these extra costs?
