Builders hide more than they show on site visits – change my mind.

Pataudi Road area keeps coming up every time I shortlist something in Gurugram. I'm looking at C S Realty's new project there, it's still under construction. Honestly, site visit pe kya dekhoon beyond the show flat? Builder log toh sab accha hi dikhate hain, right? My parents keep saying under-construction mein bahut risk hai, delivery ka pata nahi. Is C S Realty ka track record sahi hai? I'm worried about hidden costs too, like stamp duty aur registration ke alawa aur kya kya lagta hai? Not sure if I'm missing something big. Koi batao, what should I really check during a site visit for an under-construction project? Aur delivery risk kaise judge karte hain? Ab samajh nahi aa raha.
