Dwarka Expressway completion: What's the real appreciation timeline looking like?

Is the Dwarka Expressway completion really going to push prices as much as builders claim, or is it already factored in? I work in real estate, but buying for myself is totally different. Honestly, the hype around sectors like 102-113 is huge. What's the off-the-record take from people who actually bought there, maybe from M3M or Godrej? My budget's around ₹2.5 Cr for a 3BHK. Should I be looking at Dwarka Exp or Golf Course Extension like Sector 65 instead? With Global City coming up too, how long should one ideally hold a property in these areas for maximum appreciation? Not sure if the current prices (say, ₹2 Cr for a 3BHK in Sector 102) still leave enough room for decent ROI in 3-5 years. What's the community's honest opinion?
