Fees to do gift deed in hyderabad, telangana

I am planning to do a gift deed of my apartment to my mother name.

Could you let me know the current charges applicable in Hyderabad, Telangana?

Based on my research, I need to pay stamp duty, transfer duty and registration charges

A person who provides these services said about 4% combined for above 3 charges but I just want to get a second opinion, to not get taken advantage of.

Thanks in advance
