From broker to buyer – my Royalton Towers dilemma

₹10 Cr for a 4BHK in DLF Royalton Towers, sector 42 – that's the current ask I'm seeing. I work in real estate, but buying for myself is a whole different ballgame, sab marketing lagta hai. Project toh completed hai, but I'm trying to deep dive into the actual RERA compliance status post-completion. Koi hidden legal issues toh nahi hain jo market mein openly discuss nahi hote? Also, for this price point, I really need to understand the carpet area vs super area ratio. Builders ka usual trick hai, but yahan actual usable space kitna hai? Is it justified for a 10 Cr investment? And what about the investor vs end-user ratio? Don't want a ghost society for a long-term hold. What's your honest opinion on its long-term appreciation and the ease of exit after 5-7 years?
