Rajkot 3BHK: Are floor-rise premiums just non-negotiable for NRIs?

Since last year I've been trying to finalize a 3BHK in Rajkot, mainly around the 150 Feet Ring Road area. I'm based in Dubai, so it's challenging relying on broker calls and online brochures without a physical site inspection. I'm looking at projects like Ansal API's Krishna Kunj, but the pricing structure is really frustrating. They quote a base price, then these substantial 'floor-rise premiums' and 'preferential location charges' keep pushing the total cost way up. For a decent 3BHK, it's suddenly hitting ₹90 lakhs or even ₹1 crore. This feels like a bait-and-switch, especially for an investor trying to calculate a clear ROI. How much can one realistically negotiate these premiums down in Rajkot? Or are they mostly non-negotiable, especially for NRIs? I need to understand the true total cost of acquisition. Any advice on managing these unexpected add-ons?
