VVIP Group ki under-construction property mein kya red flags hain?

Talabpur Urf Hathipur — I'm looking at a 2BHK there from VVIP Group, under construction hai. Honestly, first-time buyer hoon, samajh nahi aa raha how to even shortlist properties. Parents bolte hain under-construction mein risk hota hai, especially delivery ka. Builder ka track record kaise check karte hain properly? Aur agreement mein kya kya red flags dekhne chahiye, I had no idea about half the clauses they showed me. Koi experienced banda batao, am I overthinking this?
