My own Delhi investment: Kings Homes reality check

Been seeing these New Delhi prices for years now and finally looking to put my own money in. I work in real estate, so I know the marketing spin, but buying for myself is a different ballgame. I'm eyeing The Kings Homes; it's completed, which is a plus, avoiding under-construction risks. Price range ₹1.20 Cr–₹6.00 Cr seems broad, but I'm looking at a 2BHK there. My main concern is the resale market. For a completed project, what's the actual liquidity? Is there a strong secondary market or does it sit? Also, what's the capital appreciation trend been like since its launch? I'm trying to gauge the long-term ROI here. Knowing the builder's actual delivery track record for other projects would be super helpful too, just to understand their overall quality and reputation, even if this one's done. Any real insights, off the record, would be appreciated.
