Super area numbers are screwing my 3BHK budget.

Budget finalised, loan pre-approved — ab bas ghar choose karna hai. I'm currently in a 2BHK in Sector 137, thinking of upgrading to a 3BHK in Sector 150 or near Yamuna Expressway. Honestly, is the price jump worth it for what builders like Investors Inn Infrastructure ya Gaursons actually deliver? Okay, I'll say what no one talks about enough: the super area trap. Yaar, they market a 1800 sqft flat but carpet area barely touches 1200 sqft. It's like paying for हवा! How much extra are we actually paying for common areas that we barely use? This super area inflation feels like a total scam, especially when you compare it to older properties. Does RERA even properly address this for under-construction projects? I'm already looking at ₹1.5 Cr+ for a 3BHK, and this super area difference can add lakhs. Change my mind, is it justified?
