Hi, I own a second house along with my first house.Both are purchased by taking loan from bank. House 1 is declared in IT as self occupied and therefore I am claiming tax for both principal(80C) and Interest amount. House 2 now needs to be declared as let out property. My questions are: 1) Am I supposed to show nominal rental income on house 2( although in actual it is not rented for entire year). 2) What are the documents need to be furnished to my office to get IT deduction on its loan's interest amount. 3) How shall I do the calculation for the house 2 if it is vacant for entire year. Please help me.
