Sold the big house, now confused about maintenance costs!

Kids have moved out, so sold our old place. Looking at 2BHKs now. Don't need such a big space anymore. Considering resale of existing property to fund this. Honestly not sure about maintenance charges though. Heard some builders in Noida, like Godrej, quote very low initially but then it shoots up. Is it worth going for a slightly pricier flat with lower maintenance? Anyone had a bad experience with maintenance costs with Godrej or ATS? Want something manageable, near a good hospital.
