Sector 46's hidden maintenance costs nobody talks about

The actual maintenance charges in Sector 46 can really surprise you, way more than what brokers quote. I'm so fed up of renting, my landlord raised rent again, so I'm finally looking to buy here. Doing the EMI vs rent math, seeing prices for 3BHKs around 2.5 Cr. But I'm worried about RWA effectiveness and those high monthly charges. Is the resale market strong enough there to justify these total costs? Or are there hidden expenses people only discover after possession? Need real resident insights before taking the plunge.
