Skyline Builders Sector 151 mein - sahi rahega?

Hi everyone, I'm thinking of investing in Sector 151, Noida. What do you think about Skyline Builders there? Kya kisi ne Skyline Builders ke projects mein invest kiya hai? Expected returns kaise hain? I'm confused between under-construction and ready-to-move. Which one is better for ROI? Also, what's the rental yield potential in that area? Mujhe advice chahiye. Any suggestions would be helpful! Thanks!
