Sahibabad Site 4 prices: Hidden costs are a nightmare

Visited a few projects in Sahibabad Industrial Area Site 4 last weekend. I work in real estate, but buying for myself is a different game, yaar. Builders quote one price for 2BHK units, like ₹60L, but then add so many hidden charges and PLCs. Maintenance charges bhi itne high dikha rahe hain, not sure if RWA is even effective for that amount. Matlab, are these prices even justified after all these extras? Is there any negotiation room, ya sab fixed hai? What hidden costs did you guys face after possession? Share some off-the-record advice.
