I'm asking myself the same question. We got our notice in the mail allowing us our once-a-year opportunity to pay it off. I thought mine said it was 30 years to pay it off, but as I am at work and the notice is home I will wait until later to check.
I figured it's costing me $85 per month until 2034 (if I read it correctly). I need around $12k to pay it off. Seems like a cheap way to keep $12k in my pocket even though the math says it is more expensive in the long run. I'll eventually pay 2.5 times the payoff amount. Assuming it's still my problem in 26 years.
