Empty nesters eyeing Gaurs 11th Avenue: My trick for real maintenance costs

₹8,500 for monthly maintenance at Gaurs 11th Avenue, as told by the sales team, sounds manageable for a 3BHK, but I'm wondering if that's the real figure. My wife and I are empty nesters selling our big house and looking for something compact there. We visited and the amenities looked good, especially the elevator and common areas, but how functional are they really for daily use? I always try to chat with existing residents during site visits, not just the sales folks, to get the actual picture on things like society vibe and maintenance. Any tips on verifying these costs or finding out about nearby good hospitals? Don't want any surprises after moving in. We need something genuinely easy to live in. Hope this helps someone else thinking of downsizing.
