Noida Investment: Aashi Construction Infra or elsewhere?

I'm thinking of investing in Noida. Sector 49 mein Aashi Construction Infra ka project dekh raha tha. What's the rental yield potential like in that area? Has anyone experienced dealing with Aashi Construction Infra? Kya aap logon ko pata hai about their construction quality? Also, is it a good time to buy now, or should I wait for a price correction? Mujhe advice chahiye. What do you think?
