The 2013 mortgage is on my primary home and the 2019 mortgage is on a construction loan to build my new home. I would like to know which limit ($1M or $ 750K) I need to work with for my 2019 taxes. The 2013 mortgage is for $437K and the 2019 construction loan (closed on Sept. 27) is for $1.9M. How do I calculate the correct interest deduction?
