Sector 6 Ghaziabad residents: Hidden costs aur family life ka kya haal hai?

Budget finalised, loan pre-approved for a 3BHK in Ghaziabad's Sector 6, but abhi tak hidden costs ka darr laga rehta hai. Builder ne jo bola tha, possession ke baad sab alag hi nikla. Maintenance charges bhi bohot high lag rahe hain, not sure if it's worth it. Any residents here with kids? Kids ke school admissions ka kya scene hai, aur overall safety for families? My wife is really worried about daily life aur extra expenses. Kya yahaan RWA sahi kaam karta hai? Koi unexpected costs jo aap logon ne face kiye hon?
