i had the same issue. anyone figure this out? my though about having no home for 6 months, and then a 1.5mm home loan for the last 6 months, is that you still can only take 750k of that 1.5mm, for those 6 months, not all of it. They're looking for the average of the loans, at the times you had loans, and if at any point in the year, you had over 750k on the books, you can only take the interest on 750k. So even if you had no home all year, and then closed on a home on Dec 31st with a 10 million mortgage, you'd still only be able to deduct one day of interest on 750k. Hoping that's not the case, but am totally not sure and the IRS pubs don't resolve this at all.
