Silverglades Hightown: Is the investment worth it?

My landlord just hiked rent again, so I'm finally serious about buying in Gurgaon. Looking at Silverglades Hightown Residences. Price seems steep. What's the real capital appreciation been like since pre-launch? And how's Silverglades' delivery track record? Don't want to get stuck with delays on such a big investment. Is resale liquid here?
