Upgrading dilemma: Are Bengaluru prices just too high now?

Honestly, I'm feeling a bit lost about the Bengaluru real estate market right now. Currently in a 2BHK in Bommanahalli, already have a home loan going. Thinking of upgrading to a 3BHK or maybe even a villa. Prices seem crazy. Is this current rise sustainable, or are we looking at a correction soon? I don't want to jump in if things are going to cool off. Also, when builders quote price per sqft, it never seems to be the final 'all-in' cost with PLC, parking, etc. How much extra should one realistically budget? Is the price jump for a bigger place even worth it with current rates? For future appreciation over 2 years, are areas like Sarjapur Road, Yelahanka, or Kanakapura Road still good bets, or are they already topped out? Any thoughts?
