Ashiana Black Gold Apartments

Budget finalised, loan pre-approved – now seriously looking at Ashiana Black Gold, Noida Extension. I'm in a 2BHK in Sector 78, thinking of upgrading to a 3BHK here for investment. The ₹57L-₹76L range for a completed project seems fair. My main concern is ROI. What's the actual rental yield people are getting? Is capital appreciation still strong? How liquid is the resale market for Ashiana Black Gold? Need to know if this premium justifies long-term wealth creation.
