Ghaziabad mein first home: Builder ka delivery risk kaise check karein?

₹75 lakh for a 2BHK in Siddharth Vihar — my budget is stretched, but is it worth it? I'm checking out Ekta Aarvanss Realinfra projects. Site visit pe kya kya dekhe, especially for an under-construction property? Builder toh sab acha hi bolte hain. Delivery risk kaise assess karte hain, yaar? My parents keep saying dhyan se dekhna. Should I ask for OC proof right away? Also, legal verification ke liye kya specific documents check karne chahiye? Confused hoon, any advice?
