PI Greater Noida investments: True costs & remote management?

₹95 lakh for a 3BHK in PI Greater Noida last year felt like a good pre-launch deal with Vascoda Housing & Realtech. Based in Dubai, I relied on family for verification, couldn't do a site inspection myself. Similar units now quote ₹1.05 Cr. Is this appreciation genuine, or was the 'pre-launch discount' just marketing? I need to understand the true all-in cost, including stamp duty, PLC, and potential hidden charges at possession. Should I have chosen a construction-linked payment plan instead of the initial down payment? Concerned about legal clarity and finding a reliable property manager. Any experiences with PI Greater Noida investments or managing remotely?
