My new launch vs resale price comparison

Six months into house hunting, I've noticed something. Kids have moved out; I need a manageable 2BHK/3BHK flat with an elevator, near a hospital. New launches in Sector 24C or Mohali usually show base price. Parking, PLC, club membership, electricity – sab add karke real cost bahut badh jaata hai. Resale properties often quote an all-inclusive figure, making total costs easier to compare. Doesn't this make resale seem more transparent? Sometimes per sqft looks higher, but total cost is less than new launches after all extras. Your thoughts? Any hidden costs in new projects I should know?
