Tax benefit on home loan transfer

Hi 

Please advise how I would get Tax benefit on my home loan transfer from one bank to another bank,

Here is my details

1) Taken Home loan Rs.20 Lac (A) from ABC bank in 2005
2) Taken Top-up Rs. 6 Lac (B) from same ABC bank in 2013 for renovation.

3) Transfer Home Loan (A) and Top-up (B) into XYB bank as new home loan Rs.26 Lac (C)

My house is self-occupied and construction was completed within 3 years.

Thanks for help in advance !!!
