BST Green Bhoomi

Okay I'll be honest — I completely underestimated how confusing this process is. I'm currently in a 2BHK in Sector 70 Mohali, thinking of upgrading to a 3BHK. Already have a home loan so EMI jump ka darr hai. Looking at Ace Palm Floors Apartment, it's completed which is a big plus. But BST Green Bhoomi ka future potential kya hai, even if it's pricier? Kya uski 5-year appreciation aur rental yield better hogi? Not sure agar yeh price jump justify karega.
