Hidden costs after loan approval – my Kondli shocker

Budget finalised, loan pre-approved – ab samajh nahi aa raha kaunsa ghar dekhoon. I'm looking at properties in Kondli, mostly 2BHKs, trying to find something around ₹78L. Honestly, the biggest shock after seeing a few places wasn't the property price, but all the hidden costs. Stamp duty, registration, brokerage fees, interiors ka budget – yaar, yeh sab milake toh ek chota loan aur ban jaata hai. My parents keep saying budget mein ye sab bhi include karo, but I had no idea it would be *this* much. Builders bas property price quote karte hain, PLC ya OC ka mention hi nahi karte. Should I ask about these extra charges upfront during the first site visit? What did you guys actually pay for these things? Am I missing any other major costs that nobody tells first-time buyers about until it's too late?
