Need help with 1098's 2015 & 2016

I moved into my daughter's house due to my health May 2015.  I give her the money to pay the mortage monthly.  She does not have a taxable income and does not file taxes.  Can I include her property taxes for both 2015 and 2017.  No one files the taxes on her house and since I am paying the mortage can I use her 1098 for  2015 and 2016?
