Kya Godrej, ATS, Mahagun ki society maintenance theek hai?

Maintenance charges in Noida can be a real headache. Kids moved out, looking for a smaller 2BHK around Sector 150 or 78. Godrej, ATS, ya Mahagun ke projects dekh raha hoon. Society maintenance aur post-possession charges ka kya scene hai? Koi experience share karega, especially for older folks?
