Kailash The Kings Reserve: Is the investment premium justified?

Kailash The Kings Reserve, Sector 150 – I'm currently in a 2BHK in Sector 78, thinking of upgrading. Is the ₹4.05 Cr price tag justified for a completed project? My main concern is ROI and exit strategy. Resale market kitna active hai yahan? And what's the realistic rental yield? Not sure if capital appreciation potential is still good at this price point for long-term wealth. Anyone already owning here, please share your experience. Kya yeh investment worth it hai?
