I put an ad to rent a room in my home, but didn't find a suitable renter until mid year. How do I claim my mortgage interest for the year?

My rental income, only covered my utilities and part of my mortgage.  Do I claim my rental income?

Investors and rental owners

If you were actively seeking rental income, you should be able to claim mortgage interest for the whole year.

Please keep a copy of the ad or a receipt for the ad as proof that you were seeking renters.
