Chandigarh 3BHK buyers: Real costs beyond property price?

₹1.5 Cr for a 3BHK in Sector 49, Chandigarh. Kids ke school ke paas chahiye. Property price toh pata hai, but stamp duty, registration aur other charges kitne add ho jaate hain? Kya koi way hai to manage these or reduce the impact? End-user hoon, so every rupee counts. Please share your experience.
