Question about deducting interest on mortgage on a home that I had bought for my mother

Hi,

 

I had bought a home for my mother.  Both of us are on the mortgage.  For the purpose of the mortgage, affidavit of occupancy for my mother is primary residence and for me investment property.  Am I able to deduct mortgage interest from my personal income (ie treat it as a second home for tax purposes) or does my selection on the affidavit of occupancy preclude this?

 

Thanks in advance.
