South City I mein first home hunt — prices and site visits are confusing

₹78 lakh for a 2BHK in South City I — honestly, I'm shocked by the prices. My parents keep saying Gurgaon mein toh yahi rate hai, but I don't know. I've been looking for my first home, visited a Paramount Associates project last week. Builder ka rep bas amenities aur super area bata raha tha. Mujhe samajh nahi aa raha how to even shortlist properties beyond just location. What are the key things to check during a site visit jo builder nahi batayega? Like, carpet area ka kya scene hai? Should I focus on delivery timelines ya construction quality? Any advice for a first-time buyer on what to prioritize? Am I missing some obvious red flags?
