Finding real value in Greater Noida's current market

Is the price jump from 2BHK to 3BHK in Noida Extension really justified given current market? I'm currently in a 2BHK in Omicron 1A and thinking of upgrading to a 3BHK or even a small villa. My budget is around ₹1.2 Cr, but builders like Ashiana are quoting quite high for decent locations. Lagta hai ki prices post-Jewar airport news has made everything shoot up. Are there any actual price-correction zones left in Greater Noida, like maybe towards Delta or Knowledge Park, where one can still find some value? Ya phir sab jagah same high rates hain? Also, broker-tactics ka kya scene hai? Brokers push certain projects hard, especially around Noida Extension. How do we know if it's a genuine deal for us end-users or just a high-commission unit for them? Any advice on finding better direct deals or negotiating effectively? Already have a home loan, so EMI management is crucial.
