₹75L for 2BHK in Mohan Nagar: What am I missing?

₹75 lakh for a 2BHK in Mohan Nagar is common now, but I'm genuinely worried about hidden risks. I work in real estate, but personal buying makes you paranoid, yaar. Builders often hide stuff. What about OC issues wahan? Ya fir maintenance charges baad mein skyrocket karte hain? Also, that super area vs carpet area game, kitna difference expect karein? Should I be more concerned about infrastructure problems ya builder ke after-sales service pe? What are the real red flags people have faced there? Off the record, please.
