Noida Investment: Great Value Realty or Other Options?

Hey guys, I'm looking to invest in Noida real estate. What do you think about the current market conditions? Is it a good time to buy, or should I wait for a price correction? I've been considering Great Value Realty in Sector 96. Has anyone had any experience with them? What are the expected returns and appreciation like in that area? Also, kya aap logon ko pata hai about the rental yield potential there? Which is better, investing in under-construction or ready-to-move properties in Noida right now? Mujhe advice chahiye! Any suggestions?
