My upgrade thoughts: Is 3BHK premium in New Chandigarh worth it?

Is the price difference between a good 2BHK and a 3BHK in New Chandigarh actually worth it right now? I'm currently in a 2BHK in Sector 24C, planning to upgrade. We're looking at 3BHKs or a small villa in New Chandigarh or Aerocity, maybe from Omaxe or Godrej. The jump from my current ₹90L-ish 2BHK to a ₹1.5Cr+ 3BHK is huge. Already have a home loan, so the EMI increase is a major thought. Are people seeing real appreciation on 3BHKs in these new areas, or are 2BHKs still a better value for money? Not sure if I should wait, thinking prices might cool, or jump in before the Mohali Airport expansion and PR7 Airport Road completion push prices up further. Kya lagta hai, is the premium justified for the space?
