Under-construction projects in Gr Noida are a huge gamble, change my mind.

Under-construction projects in Gr Noida are a huge gamble, change my mind. Everyone glorifies the price advantage, but delivery risk ka kya? Especially for first-time buyers like me. I'm looking at some Prasu Infrabuild projects in Sector 16, brochure toh mast hai. But builder ka track record kaise check karte hain? RERA check kar liya, par title search, encumbrance certificate, yeh sab kitna important hai? I'm honestly not sure. My parents keep saying ready-to-move lo, but budget constraints hain. Kya under-construction mein itna risk lena worth it hai? Matlab, log bolte hain ROI achha milta hai, par agar 5 saal tak possession hi na mile toh? Ab samajh nahi aa raha. Disagree? Tell me why.
