Stuck on Bengaluru investment strategy from abroad

Honestly, I'm feeling pretty lost trying to figure out Bengaluru property from Dubai. Looking at a Prestige project near Lalbagh Road, quoted around ₹1.4 Cr for a 2BHK. What's the *real* all-in cost? How much do stamp duty, registration, and PLC typically add up? Also, for an investor, is a construction-linked payment plan smarter than a higher down payment? Can't do site visits, so relying on your ground truth.
