My ₹45k rent is pushing me to Trehan 71.

₹45k rent every month is just burning a hole, so I'm finally looking at Trehan Luxury Floors 71. Price is around ₹2.17 Cr. What's the real capital appreciation been like since launch? And for investors, what kind of rental yield can one actually expect here? I'm worried about delivery delays too; does Trehan have a good track record?
