My first property hunt: Hyderabad edition

Builder's 'final' price is never actually final, trust me. I work in real estate, but buying my own 3BHK in Attapur with Salarpuria Sattva, I'm seeing so many hidden charges. Matlab, PLC, floor-rise, maintenance deposit... yeh sab brochure mein clear nahi hota. Kya koi special way hai to negotiate these *after* the initial price? Yaar, log bolte hain spot discount milta hai, but kitna realistic hai? Aur possession ke time kaunse unexpected costs aate hain jo builders chupate hain? Need real experiences, especially from Hyderabad. Hope this helps someone else too.
