NJ Property Tax Deduction for a Co-Owned Property

[bryanbrt18]

My girlfriend and I co-own a property. However, only I live in the property 100% of the time and pay 100% of the mortgage. She is not on the loan and has no income. Can I claim the full deduction or can I only claim 50%?

The turbo tax questions have me only claiming half with the way it is asked, unless I am misinterpreting it and should put 100% of ownership?

If you are the only one paying the mortgage, then you are the only one who would claim the mortgage interest deduction as an itemized expense.

Sorry, I updated the question as I didn’t ask it correctly.

If you made all the mortgage payments, you would be able to claim 100% of the deductions.  In your situation, you could enter that you owned the house 100% so TurboTax does not divide the amounts and/or you do not have to edit them (as in the screenshots you provided).  @bryanbrt18
