Stuck on Mahagun Moderne's investment potential

What's the real ground reality for capital appreciation in Mahagun Moderne, Noida? I'm eyeing a 2BHK there, around ₹1.4 Cr. For investors, what kind of rental yield can one actually expect? Brochure numbers always look great, but I need honest opinions. Is the resale market liquid enough if I plan to exit in 5-7 years? Honestly not sure if Noida's long-term growth is still strong. My parents keep saying it's slowed down.
