Noida mein investment: Grihapravesh Buildteck sahi hai?

Guys, Noida mein property dekh raha hu. Grihapravesh Buildteck Pvt Ltd ka koi project Salarpur Khadar mein hai. Anyone invested there? What's the expected appreciation? I'm confused about under-construction vs ready-to-move. Which one is better for ROI in Noida right now? Rental yield potential kaisa hai Salarpur Khadar mein? Please share your experiences and advice. Kya karna chahiye? Mujhe advice chahiye...
