Investment Hotspots infra: My first property dilemma

Budget finalised, loan pre-approved – now stuck on which sector to focus on for my first property. I've been looking around Bangalore, mostly for a 2BHK. My parents keep saying 'Investment Hotspots' is the place to be for appreciation, but honestly, I'm not sure if it's just hype. I heard about the Peripheral Ring Road moving forward and how that affects prices. What pockets along Investment Hotspots have actually seen a real jump because of the new metro lines or road upgrades? Is it too late to get in? I visited a couple of projects, not naming them, but the brokers there were quoting crazy PLCs. Is the appreciation real, or just speculative? Any advice from people who've bought there recently would be super helpful.
