Ghaziabad hidden charges: What did you pay extra?

Modern Railway City — just got possession for my 2BHK with Skardi Realtech a couple of months back. Honestly, the final costs were way higher than what I'd budgeted. I knew about stamp duty and registration, but the builder sprung so many 'miscellaneous' charges at the last minute. Things like unexpected maintenance deposits, utility connection fees, and even some obscure development charges that weren't clearly mentioned initially. My ₹65L flat ended up pushing ₹70L easily. Did anyone else face this with their Ghaziabad property, especially in areas like Vaishali or Raj Nagar Extension? How do you even factor in these hidden costs, or negotiate them down? I feel a bit cheated, tbh.
