What is the Grad Plus interest rate? Isn't it something nuts like 8.5%?
Yeah, plus there's a 3% origination fee. Blech. There are no aggregate limits to how much you can borrow, though, so there might be an advantage if you already have crushing undergrad debt. I'm not sure.
I think it all comes down to what you think interest rates are going to do during the next ten or so years. Me, I figure that rising fuel costs are going to be playing merry hell with the economy, so interest rates probably won't get much higher than they are right now. I could be wrong, though. Bernanke seems a bit more aggressive than Greenspan, and you'd need a crystal ball to accurately predict what the economy's going to do.
