The Antriksh Heights

What's the real capital appreciation like for The Antriksh Heights, honestly? I'm currently in a 2BHK in Sector 70 and thinking of upgrading to a 3BHK or even a villa there. The current price range seems pretty high, honestly not sure if the premium for a completed project is justified for long-term ROI. Has anyone invested there recently? What kind of rental yield are people actually seeing for a 3BHK? My main concern is liquidity and the resale market. Is it active? Who would buy a unit from me in say, 5-7 years if I decide to exit? Already have a home loan, so need to be smart about this next big move.
