I am in a similar situation. I purchased a second home as my primary residence now. I kept my first house which I lived in for 6 months of the year and rented it out for the last 6 months. I understand I have to enter both houses as primary residences with their respective dates to claim the mortgage interest as a deduction. But then I have to enter one of them as the rental property to report the rental income. How do I report the mortgage interest if the 1098 shows the interest for the entire year and the rental was only for 6 months? I just want to make sure that the mortgage interest is not being entered twice and considered "double dipping". Thanks!
