Is my (primary) home equity loan interest deductible, if I use the proceeds to pay off the outstanding mortgage of my second home?

[lafiosca]

I own my primary home outright (no mortgage). Rather than pay the closing costs for refinancing the mortgage of the second home, I'm contemplating the home equity loan to pay off the second home mortgage.

No. The interest from a home equity loan or line of credit is only deductible if it is used to buy, build, or substantially improve the home that is secured by the loan. As it would be used to pay off another property, the interest would not be deductible.
