Visited Goyal Luxury Floors — worried about upcoming project delays

Did a site visit to Goyal Luxury Floors By Rahul Mangla on Saturday. Currently in a 2BHK in Sector 14, I'm thinking of upgrading to a 3BHK for investment purposes. The ₹2.65 Cr price feels like a big commitment for an upcoming project. My main concern is the possession timeline. Builder ka track record kaisa hai for actual delivery dates? Investors ke liye delayed projects kaafi costly ho jaate hain. Will these luxury floors actually be ready on time? What's the real ground reality for Rahul Mangla's past projects regarding possession? Don't want my capital stuck with no rental income or appreciation...
