Mortgage question–are variable rates no-nos?

Just curious about the community’s opinion on mortgages right now. We’re deciding between financing 80% of our purchase with a jumbo loan at just over 7% (fixed)–or taking out a conforming loan for 65% of the price at a much lower rate and financing the remainder 15% through a home equity line-of-credit (still with 20% down).

The latter rate is, of course, variable (at prime) which we are worried about with the uncertainty of financial markets. But spliting the mortgage in this way could save us a lot if rates don’t skyrocket.

Any advice? We plan to stay in the place for the long-run–hopefully, 10 years or so.

Thanks!
