Payment plans and the hidden cost of a 'view'

Okay I'll be honest — I work in real estate but buying for myself is completely different, it's confusing. I'm looking at a 3BHK in Sector 117, maybe Virasat Group. They're pushing CLPs hard. Is a construction-linked payment plan always smarter than a down payment for an investor like me? And what about FLR/PLC? The agent says it's worth it for a higher floor view towards Jewar, but it adds like 4-5 lakhs for a ₹1.2Cr flat. Am I missing something, or are these just fancy ways to inflate the price? What's your take?
