Hello, I have a client that had his primary residence with a mortgage $800K post 2017. In December 22, they closed on another home to move in with a mortgage $1.1M. What's the best way to calculate the average balance in this case? When I enter the 2 loans in the mortgage interest worksheet, it calculates an average of balance of $1.8M which seems too high considering the second home closed at the end of the year. Thank you!
