Thanks for the reply. I have been studying IRS 936 carefully. I started to believe in my case the mortgage interest is not deductible. The IRS publication says:
Home acquisition debt is a mortgage you took out after October 13, 1987, to buy, build, or substantially improve a qualified home (your main or second home). It must also be secured by THAT home.
DMarkM1 just argued that I used a mortgage secured by my main home to buy a second home, but that case does not seem to qualify as home acquisition debt, right?
Thanks!
