Prestige City: The real investment picture?

Did a site visit to Prestige City on Saturday and the amenities looked great. I'm thinking of investing here, but thoda darr lag raha hai. Kya iska capital appreciation sahi mein utna hoga jitna builders bolte hain? Aur rental yield actual mein kitna milta hai? Investor ratio bhi high lag raha, ghost society ka risk toh nahi?
