Anil Suri Group: What current residents wish they knew about hidden charges

Since last Diwali, I've been eyeing flats in South Delhi, and Anil Suri Group's CGHS Gauri Ganesh Apartment dekh raha hoon. Looks decent on paper, but I'm super worried about hidden charges. Yaar, possession ke time pe PLC, maintenance deposits, ya koi aur unexpected costs kitne add ho jaate hain? Honestly not sure if the initial quote is the real deal. Also, construction quality ka bhi tension hai – sunte hai plaster cracks aur seepage issues aate hain. Jinhone yahan se liya hai, apna experience share karo na please. First-time buyer hoon, ab samajh nahi aa raha.
