Dev Sai Solitairian City Pary's appreciation is just average

For months I've been tracking ready-to-move options in Noida. Dev Sai Solitairian City Pary looks interesting for investment. What's the real capital appreciation like since possession? Is the current price per sqft justified? Also, what kind of rental yield are people actually getting there? I worry about the investor-to-end-user ratio impacting rentals and eventual resale. Anyone have ground-level insights or experience with this project? Don't want to get stuck in a ghost society, you know?
