On February 11, 2013, we paid off our bank mortgage. The bulk of the funds came from an interest incurring loan from my parents, at a lower rate than our mortgage, which we couldn't re-fi since it is no longer owner occupied. The rest of the money came from our HELOC, which is currently at 2.6%, but is adjustable. Even though it's a great rate, the "adjustable" part isn't comfortable, so we've been really pushing to get rid of it, throwing all extra cash we have at it. I checked today, and since February, we've paid off over $10k in principal! And this is with the loss of my income since we moved to Germany in December.
