New Launch Projects pricing — anyone else seeing these hidden costs?

Property prices in the New Launch Projects corridor jumped 25% in the last 18 months, or so they say. I'm currently in a 2BHK in Marathahalli and thinking of upgrading to a 3BHK or villa. Every site visit, the quoted base price feels okay, but then the PLC, floor rise, amenities charges, and frankly, some absurd 'other' charges add another 15-20 lakhs. It's frustrating. I already have a home loan and was hoping for a smoother transition. Is this premium justified now or should I just wait? Are others facing these crazy hidden costs in new projects too? Wondering if I should just hold off another year...
