My personal property hunt: 2BHK vs 3BHK ROI in South Delhi.

₹1.8 Cr for a 2BHK in Saket — is this the new normal for good areas? I work in real estate, but personal investment is tough. Looking at Saket, Vasant Kunj. 2BHK for ₹1.8 Cr, 3BHK ₹3.5 Cr. Which gives better rental yield and appreciation in South Delhi? DLF, Godrej Properties ke rates high hain. Should I stretch for 3BHK ROI?
