Luxury Homes corridor buying – what did I miss?

Just got possession of my flat in the Luxury Homes corridor last month, and honestly, kuch cheezein unexpected nikli. Maintenance charges bahut high hain, aur hidden costs jaise club membership ke liye alag se demand karte hain. Builder ne bahut promises kiye the, but actual amenities ka usage utna nahi hai. Is there any hidden risk in Luxury Homes buying that people usually miss? Resale value ko lekar bhi thoda doubt ho raha hai. Any red flags you've noticed after moving in? Your experiences will be really helpful.
