1) The property is the primary residence for my child who is single, and I have my primary residence (separate mortgage and property tax) with my spouse. 2) I paid the down payment on the second house and the property payment in 2017, and my child paid the mortgage. 3) My child can take the standard deduction, but I file jointly with spouse using itemization. I am wondering what is the best to do for 2017 tax return and also for the future. I am worried that my child did not directly put in for the down payment and it would complicate things. Thanks!
