Bangalore home buying mein kya kya hidden costs hain?

Been looking for 6 months now and ab samajh aa raha hai ki property ka cost sirf base price nahi hota. My budget for a 2BHK in Sankey Road / Malleshwaram extension was around ₹78L, but uske upar kitne hidden costs hain yaar. Stamp duty, registration, lawyer fees, then interiors... I had no idea it adds up so much. Keya Homes ke ek project mein interested hoon, but not sure about all these extra charges. Site visit pe kya kya ask karna chahiye beyond just the flat? Like, maintenance deposit kitna, club house fees, parking PLC, electricity connection charges. These things can easily add 10-15% more. Any hidden charges people found after booking? Share your experiences, please!
