If i move mid year to another house, do i get the mortgage interest deduction & Property tax deduc for all mortgage interest paid to both properties for the entire year?

I moved to a new property mid 2015. I kept the incumbent property and later used it as a rental.  I paid mortgage interest for the entire year on the incumbent property. I paid mortgage interest for part of the year on the new property i moved into.  I paid property taxes for both properties for the entire year.  

For the mortgage insurance deduction:  do i have to prorate what i deduct from both properties based on many days i lived in each property? Or, do i get to take all interest paid from both properties?

Same question for the property taxes.
