NK Vaishnav Apartment: First investment confusion

Honestly, I'm finding this whole property investment thing way more confusing than I imagined. I'm looking at NK Vaishnav Apartment in Delhi, it's completed, so delivery ka tension nahi hai. As a first-time investor, I'm really focused on long-term ROI and wealth creation. Has anyone here invested there? What's the actual capital appreciation like since it completed? Matlab, price kitna badha hai over the years? Also, rental yield actual mein kitna milta hai? Online numbers vary a lot. And for resale, is the market liquid? Will it be easy to exit in 5-7 years if needed? My parents keep saying location matters most, but I need real data. Am I overthinking this, yaar? Any advice from experienced people would be super helpful.
