Under-construction project risk in Gurugram?

Visited Paras Buildtech in Sector 82A last Saturday. Under-construction project hai, toh thoda dar lag raha hai delivery ka. First-time buyer hoon, shortlisting properties bahut tough hai. Site visit pe kya important points check karne chahiye jo builder nahi batayega? Specifically for under-construction, how do you assess builder's delivery risk? Parents ready-to-move bol rahe hain, but budget mein nahi aa raha. Any advice on managing under-construction uncertainty? Kya Paras ka track record sahi hai?
