Hyderabad flat buying: stamp duty kitni lagti hai?

Our kids have moved out, so we're selling our big house and looking for a smaller, manageable 2BHK flat in Hyderabad. Uppal side dekh rahe hain, maybe Salarpuria Sattva ke projects. Mera main concern total all-in cost hai. Builder price ke alawa stamp duty, registration, ye sab kitna add ho jaata hai? Broker ke through jaana better hai ya direct builder se deal karein for better pricing? Kya brokers sach mein koi good deal nikal sakte hain? Please share your experience.
