Hyderabad still has hidden value zones

₹2.1 Cr for a 3BHK in Kokapet is just crazy, I'm fed up of renting but these prices... Honestly, I'm looking for actual price correction zones in Hyderabad, not just the usual Gachibowli hype. Are there any pockets left with real value, or is everything inflated? Also, how much do those 'hidden' charges really add up at possession?
