Married last year and we each owned homes, one is now rented
I am trying to figure out where to list mortgage interest in relation to what is now a second home rental property. I got married in the end of June. My wife has a townhouse that was her primary residence up until that point. It was then rented out the first part of July. Since she lived in it for more than 14 days or 10% of the year (I think those were the stipulations), do we list the mortgage interest under deductions along with the mortgage interest for my house that is now our primary residence? Or do I list that mortgage interest under rental deductions/expenses along with other rental property expenses and income? And with that, in the rental section, do I only include expenses (mortgage payments, utilities, HOA, etc) for the time that it was rented out last year from July-December? Or do we include those expenses for the whole year, which would include the months that it was my wife's primary residence?
