Noida Investment: ATA Investor Home, Sector 143 - worth it?

I'm looking to invest in Noida, specifically considering ATA Investor Home Pvt. Ltd. in Sector 143. What's your take on the expected returns there? Is it a good area for long-term appreciation, or are there better options? Kya aap logon ko pata hai about the rental yield potential in that area? Also, I'm torn between under-construction and ready-to-move properties. Which one would you recommend for maximizing ROI? Has anyone experienced significant construction delays with ATA Investor Home? Mujhe advice chahiye on the risks involved in investing now versus waiting. What do you think?
