Hello sir,
For RTC it is Rs.10/-
For khatha transfer there are two procedurs
1. if land is leased
2. if full purchase
For wet land it is around Rs. 26.000/- per acre- based on stamp duty
for dry land it is around Rs. 8,000/- per acre
Example; if u purchase Paddy field- Rs.2.0 lakhs
Now the procedure has been changed in Karnataka. U can approach the nearest Survey officer for the clarification.
Regards
