Noida investment: Shivkala Group or Noida Extension?

Hey guys, I'm thinking of investing in Noida real estate. What do you think about the year-on-year growth trends? Is it a good time to buy, considering current market conditions? I'm confused between investing in Shivkala Group projects and properties in Noida Extension. Which one offers better ROI in the long run? Has anyone experienced dealing with Shivkala Group? Kya aap logon ko pata hai about their construction quality? I'm also considering rental yield potential. Which option gives better rental income? Mujhe advice chahiye! Is it worth investing in under-construction properties in Noida Extension? What's your take? Any suggestions?
