Confused about Ghaziabad's infrastructure price impact

How much have Ghaziabad's new roads and metro really impacted property prices in the 'New Launch Projects' corridor? I'm looking there, but honestly, can't tell if current price hikes are justified. Which pockets, like near Hindon or Vaishali, saw the most genuine benefit? My parents say it's just speculation. Is the premium worth it for first-time buyers?
