Thinking of upgrading to a villa — insane price jump!

I'm currently in a 2BHK in Sector 9, and now thinking of upgrading to a 3BHK or maybe even a villa. But the price jump is insane! Is it really worth it? Like, the EMIs will be double, and I already have a home loan running. Has anyone here made the switch from a flat to a villa? What's your experience been like? I'm looking at some Assotech Limited projects, but honestly not sure if the extra space is worth the extra cost. Kya return milega? Also, plot vs flat, which gives better returns in Noida these days? Koi idea hai?
