My Gurugram 3BHK hunt: Parkview Apartments dilemma

Not proud of this but I almost got duped by a pre-launch scheme last year. Now, I'm seriously looking at Parkview Apartments, thinking of upgrading from my current 2BHK. My main concern is the investor angle. Iska capital appreciation forecast kaisa hai? Builders ne launch ke baad price kitna badhaya hai? I'm already carrying a home loan, so is this ₹2.65 Cr–₹3.50 Cr premium justified for long-term wealth creation? Resale market kitna liquid hai yahan? Will it be easy to find a buyer in 5-7 years, ya ghost society ban jayegi because of high investor ratio? Jo log already reh rahe hain, unka kya experience hai rental yield ka? Any advice on exit strategy?
