Yamuna Exp. plans: Pre-launch vs. CLPs

Yamuna Expressway Sector-22D mein Victory Infra projects dekh raha hoon. I'm based in Dubai, so site visits mushkil hain. Pre-launch pricing ka kya scene hai? Matlab, is it genuinely cheaper ya just hype? Also, CLP (Construction Linked Plan) vs upfront payment, which option makes more sense for ROI and legal clarity for an NRI? Total cost mein stamp duty aur PLC kitna add ho jaata hai?
