From 2BHK to villa – my Kannamangala upgrade dilemma

Past few months se I'm seriously looking at upgrading from my 2BHK in Whitefield. Kannamangala side, Ballari Road pe villas dekh raha hoon. Prices toh astronomical lag rahe hain, yaar, I'm already on a home loan. Is this price jump for a 3BHK or villa really worth it? Builders like Prestige aur Sobha ke projects hain wahan. Kya real appreciation potential hai 3-5 saal mein? Ya sirf current hype hai? Traffic ka bhi darr hai airport side ka. Kitna time lagta hai peak hours mein?
