Concerning rental income and SARS?

In January my wife and I we relocated. We started renting out our house since beginning of Jan 2015. In my tax return, must I count the rental income only for January and February, and subtract cost ie monthly repayment on the home loan and agent commissions?

You would be able to deduct all expenses related to renting out the house. So this would be the agent's fees, the electricity, rates and taxes, the interest on the bond (not the capital repayments) and any other expenses you have for this property. Yes it would only relate to the period you rented out the house.
