- QuestionnairePotentially, as it comes down to what you use the proceeds for (under the interest tracing rules) and if it is a valid tax deductible purpose or not.  

For example, if it is used to purchase or substantially improve a home, it would be qualifying home acquisition debt, and depending on the total mortgages (as post TJCA, federally, you are limited to an itemized deduction for interest on up to $750k of home acquisition debt).  Though, it sounds like you may already be over the limit there (as it sounds like you have $1.3M-1.4M first mortgage, if you only have $470k of equity in a $1.8M property).
