My landlord hiked rent again, and I'm convinced 2BHKs are the real play here

My landlord just hiked rent again, I'm done paying EMI to someone else. Finally taking the plunge in Greater Noida. Honestly, everyone glorifies 3BHKs for investment, but I think 2BHKs make more sense. Especially in Noida Extension ya Knowledge Park ke paas. Lower entry cost, easier to rent out to students/young professionals. Matlab, 3BHK ka rental yield itna achha nahi lagta. What's the scene with appreciation for 2BHKs compared to 3BHKs in these areas? Builders like Gaurs or ATS mein kiska 2BHK better hai for long term? Is my math wrong? Change my mind.
