3BHKs in Noida Extension offer better long-term ROI

Is a 3BHK in Noida Extension a better investment than a 2BHK for rental yield and appreciation? I'm eyeing buys near Knowledge Park. Initially, I thought 2BHK (₹80-90L). But a 3BHK (₹1.2-1.4Cr) might give better ROI. My experience says families prefer bigger spaces. With Jewar Airport and Metro extension, the IT crowd is growing. Won't that boost 3BHK demand? What's the real ground reality for rental yields? Is a 2BHK easier to sell, or does a 3BHK offer better overall gains? Any thoughts on builders like Gaurs Group or ATS?
