Hi all.

> I did the following rough calculation on the potential benefits of taking out a home equity loan in order to pay down a student loan (of size $113,000). We cannot deduct student loan interest because our household income is too high. So an accountant mentioned the possibility of taking out a home equity loan (HEL) and deducting the interest from that HEL loan.

Forgetting for a moment the time value of money....
A 15 year loan of $113,000 at 2% equals payments of $130,890. Use 3.85% and the payments are $148,928. That is an extra $18,038 of interest. A HELOC of $100,000 (that's the max on which you can deduct interest) at
3.85% would have payments that equal $131,795. That is deductible interest of $31,795. A 28% tax benefit on $31,795 is no where near your additional interest of $18,038.
