Rajkot property: Kitna extra budget karein beyond flat price?

Did a site visit to Ansal API Krishna Kunj last Saturday and honestly wasn't expecting this. The flat price sounded okay, but then the broker started listing so many extra charges. PLC, society maintenance, registration, stamp duty, interiors, electricity connection... yaar, it's a lot. My budget is around ₹78L for the flat, but these extras are adding up to like another ₹10-12L easily. Not sure if this is normal for Rajkot or if I'm just naive as a first-time buyer. Seniors, aap logon ko kitna extra laga tha beyond the property value? Any tips on budgeting for these, ya in pe negotiation possible hai?
