Maintenance charges: The silent killer for investor ROI?

Honestly, after getting possession at Shatabdi Rail Vihar, I'm a bit concerned about the long-term picture. The monthly maintenance charges are quite high, but the actual service quality for things like security and clubhouse upkeep feels... off. For investors, isn't this crucial for tenant retention and resale value? I mean, who wants to pay premium maintenance for ghost facilities? Are others noticing this too in Greater Noida projects? Should I be factoring in higher vacancy rates or reduced rental yield because of this? What's your experience?
