Mohali investment: Struggling to find real value remotely

Honestly, I'm finding it tough to identify real value for money in Mohali from Dubai. I'm based here, so site inspections can't happen easily. Looking for a 2BHK investment in Mohali, maybe Sectors 82-84, budget around ₹1.5 Cr. Builders like Imperialstone Infraparks ka secondary market track record kaisa hai? Are there 'price correction zones' for resale properties? I need all-in cost breakdown. Does negotiation in secondary market work better than new projects? And remote NRI property management kaise handle karte hain log?
