First villa, but hidden costs are killing me

Been looking for 8 months now and it's getting exhausting. Finally thought Paradise Krishna Vatika villas were perfect, price bhi set ho gaya tha. But signing ke time they dumped so many 'additional charges' on me. Brochure mein 'all-inclusive' bola tha, but registration, IGL connection, maintenance advance — sab alag se. My initial budget of ₹1.15 Cr jumped by almost ₹10 lakhs! Honestly, this feels like a big scam. Did anyone else buying here face such a huge difference between quoted and actual cost? Kya karna chahiye?
