Bengaluru amenity promises: investor's reality check

₹1.5 Cr for a 3BHK in BCD Aikam Golf Estates Phase I. As an investor, I see builders promise a lot. But amenity reality kya hai? Maintenance charges kitne hain aur service kaisi milti hai? Clubhouse sirf showpiece hai ya actually use hota hai? Resale value pe kitna impact aata hai agar amenities bas paper pe hain?
