Sale agreement and registering a property in bangalore

Q: Hi friends,

I am planning to purchase one BDA approved plot.
Legal verification of the property is done and will be doing the sale agreement next week.

I would like your opinion whether I should take help from an agent for property registration and khatha transfer.
In many online forum, it is said we can do it without much hassle, But I am a non kannadiga, and my kannada knowledge is 2 on a scale of 1 - 10 :?

The agent is asking for huge amount for getting it done, he says this inclused all like agreement, writing charges, khtha transfer(including under the table payments) not including the stamp and registration charges.

The property tax is payed up to date, all the documents are up to date, and I am registering for the exact amount I am purchasing.

Kindly give your opinion / experience.

Thanks.
