My 2BHK upgrade dilemma in Rajkot

Okay I'll be honest — I completely underestimated how confusing this process is. I'm currently in a 2BHK near Krishna Kunj, and thinking of upgrading to a 3BHK or maybe even a small villa. My budget's around ₹1.2 Cr, but honestly, not sure if the price jump is worth it for a 3BHK. Is the premium for a bigger place, say by Balaji Group or Galaxy Group, in areas like 150 Feet Ring Road or Mota Mava actually justified in terms of future appreciation? I already have a home loan so the EMI jump is a big factor. Should I wait a bit more, or is now a good time to buy given the AIIMS and Airport impact? Also, any real experiences with construction quality from these builders? Don't want project delays.
