I am looking for a bit of direction. I bought a house, then moved and its been rented for the past 7 years. In 2012 my tenants lived in it for 6 months and when they moved out, I lived in the remaining 6 months of the year while I got it back into shape. My question is: how do I claim the mortgage interest on my taxes? Do I claim half as the rental and half as primary residence?
