Real appreciation timing for Greater Noida infrastructure

Budget finalised, loan pre-approved – now stuck on which sector. My experience from past investments, like near Pari Chowk, shows real appreciation for Greater Noida properties often spikes *after* major infra like Jewar Airport or Aqua Line extension is physically complete, not just announced. Exiting too early can miss peak ROI. I'm eyeing Yamuna Expressway for this. Do others time their exits based on actual project completion for maximum gain? What are your strategies?
