Greater Noida West: Pre-launch ka asli fayda kya?

Pre-launch deals in Greater Noida West often feel like a trap, honestly. Strategic Developers ka ek project dekh raha tha, they're pushing pre-launch rates but later open-market mein price difference zyada nahi dikhta. Is early-bird discount worth it, ya bas hype hai for investors? Also, construction-linked payment plan zyada better hai for investors or down payment scheme? My parents keep saying down payment is less risky but ROI ke liye toh CLP sahi lagta hai. Koi experience share kar sakta hai? Am I missing something big?
