Ghaziabad builders: What happens after you get possession?

₹95 lakh for a 3BHK in Raj Nagar Extension is what I'm seeing for ATS projects. From my experience, delivery track record aur construction quality matter a lot. ATS ka naam toh acha hai, but kya construction quality sahi mein expect kar sakte hain? Aur Gaurs ya Mahagun ka kya scene hai Indirapuram mein? My main concern is post-possession customer support aur maintenance charges. Kya builders delivery ke baad bhi responsive rehte hain, ya bas flat hand over karke bhool jaate hain? Has anyone faced issues with high maintenance or poor society management after a few years?
