My Greater Noida 2BHK search: Hidden costs are scary.

My kids have moved out, and honestly, this big house feels too much now. I'm looking for a manageable 2BHK in Greater Noida, maybe around Sector 97. The Hemisphere looks interesting, but the initial quotes always seem lower than the final figure. I'm really worried about hidden charges. What's the real all-in cost for something around ₹80L after stamp duty, registration, and all the extras? What common surprise charges did you face at possession time? Things like PLC, parking, club fees... it's confusing.
