My honest concerns about Dasnac Burj Noida

Been tracking Dasnac Burj Noida since I'm based in Dubai. Prices are crazy, touching ₹4Cr for a 3BHK. What's the realistic capital appreciation potential here? Also, what's their actual delivery track record like? I can't do site inspections, so relying on community insights. What kind of rental yields are people actually getting? Need opinions before committing.
