The information regarding Turbotax automatically handling interest proration between rental and primary residence is useful. My question was however regarding mortgage balance. When calculating total mortgage balance in pub 936, do I use the full mortgage of house A or can I also prorate the mortgage pf house A? Or can I deduct all of the interest because my mortgage balance for primary residence, whether living in house A or house B, never exceeded $750,000?
