null's Paradise Enclave actual carpet area seems off

New Chandigarh mein property dekh raha hu, especially for a 2BHK near Aerocity. Budget ₹85L tak hai. null ka Paradise Enclave aur Raheja Universal ka Raheja Winterwoods shortlist kiya hai. Paradise Enclave mein quoted super area aur actual carpet area kaafi different laga, ya phir main galat hu? Possession ke time kya unexpected costs aate hain, like maintenance deposits ya PLC? Aur post-possession maintenance fees ka kya scene hai in projects? Winterwoods ke residents, aapka overall experience kaisa raha?
