My Noida Extension flat search: infra delays making me rethink

Since kids moved out last year, I'm looking for a smaller flat, maybe Swarn Nagri or Sector 150. But yaar, I'm so frustrated with all these infra project delays. Builders keep hyping Jewar Airport and FNG Expressway, but completion dates just stretch. Will prices still appreciate if the Aqua Line extension takes forever? Don't want to buy something jahan life time delays hi ho.
