Noida market peak - my own dilemma

Okay, I thought I knew all the tricks, but buying for myself is a whole different ballgame. I'm looking at a 3BHK in Sector 150, maybe Godrej or ATS. Builder quotes are around ₹1.8 Cr. My concern is, with Jewar Airport coming up, kya prices already peaked out hain? I know the FNG Expressway will help, but will the appreciation continue till 2026-27? Ya phir abhi hold karke wait karna better hai? What's the general sentiment, market abhi bhi upar jayega?
