Noida Sector 90 investment: Siwas Infra sahi hai?

I'm thinking of investing in Noida Sector 90. What's the rental yield potential there? Kya aap logon ko pata hai Siwas Infra projects kaise hain? Are they worth the investment, considering the current market conditions? I'm looking for long-term appreciation. Has anyone experienced any issues with Siwas Infra? Mujhe advice chahiye. Which one is better for investment purposes, under-construction or ready-to-move properties, considering the risks? What's your take?
