Pre-launch vs. secondary market for investment: Which is the bigger gamble?

Is pre-launch pricing in Ghaziabad actually a scam? Everyone glorifies early-bird discounts at places like Panchsheel Greens or even new projects around Madhopura, but I'm honestly not seeing the real upside. Aren't you just locking funds for years with no guarantee? My parents keep saying secondary market deals in Indirapuram or Vasundhara are better for finding value. You can actually see the property, right? Plus, are construction-linked payment plans really smarter than just waiting for ready-to-move and taking a bigger loan? Change my mind.
