What Gaur Saundaryam investors aren't telling you about yield.

Budget finalised, loan pre-approved – now stuck on Gaur Saundaryam for investment. I'm looking at the ₹1.95 Cr units. I work in real estate, so I know marketing spin, but what's the actual rental yield people are getting there? Has capital appreciation been decent post-completion? And is the resale market liquid enough, or is it mostly investors there creating ghost society risk?
