Selling big house, Rajkot flat needs real picture

Is the RWA in Krishna Kunj actually effective with maintenance charges? Humara bada ghar bech ke ab chhote flat mein shift hona hai, kids have moved out. Low maintenance cost aur good society chahiye. Builders jaise Maruti Group ya Balaji Group ka track record Rajkot mein after-sales kaisa hai? Pani ki supply aur borewell reliability kaisi hai wahan? Don't want daily hassles after moving. Koi hidden costs bhi hain kya?
