I refinanced home on 03/03/2016 and converted it to a rental property on 03/17/2016. How do I report 1098 forms, and how to I allocate the mortgage interest/insurance?

Just to clarify: From 01 JAN - 15 MAR 2016, the property was primary residence.  From 16 MAR - 31 DEC 2016, the property was a rental.

I received two 1098 forms due to the refinance on 03 MAR.  The second 1098 covers a period of both personal use and rental use.  How do I report/allocate the mortgage interest/insurance between personal use and rental?
