Ike and Tina were married in 2013 and shortly thereafter purchased a home by taking out a $300,000 mortgage. In 2017, Ike and Tina divorced. The divorce decree gave sole possession and ownership of the house to Ike. However, Tina was to continue making the mortgage payments as part of her spousal maintenance obligation. Are these payments deductible in full or in part by Tina as home-interest expense or alimony, or are they payments on a debt obligation and not deductible?
