The real premium for Gurugram's infrastructure upgrades?

The price jump for a 3BHK or villa in Gurugram feels insane right now. I'm currently in a 2BHK in Sector 82, and thinking of upgrading, but honestly not sure if the premium for a bigger place is justified. We're looking at places around Golf Course Extension Road or even near Dwarka Expressway, perhaps M3M or Godrej projects. My budget is around ₹3-4 Cr. Is the market for 3BHKs or villas at this price point truly sustainable, or is it just overheated? I already have a home loan, so this next one will be a big stretch. What are people's thoughts on future appreciation, especially with Dwarka Expressway completing soon and Global City coming up? Will these specific areas give solid ROI or are we buying at the peak? Should I wait a bit? Would love to hear experiences or if anyone's made a similar jump.
