NRI trying to buy property remotely — this is hard

Did some research on Noida projects from Dubai this week, especially in Sector 150. Main invest karna chahta hoon but can't do site inspections. Godrej Properties, ATS, and M3M India are on my radar. How's their on-time delivery track record, honestly? Aur construction quality mein kaunsa builder reliable hai, no hidden issues baad mein? What are your experiences with Gaursons or ACE Group's post-possession quality in Noida?
