re: 5yr. Balloon Loan w/ 10yr. Amort. (Any hidden things I should worry about?)

I don't really understand what you are doing here then, why are you trying to transfer studen loans into a personal loan? Are you really able to get a better personal loan rate then student loan rates? Have you looked at other long term student loan refinance rates? I haven't in years and I'm ignorant here, I just have never heard of anyone transferring student loan debt into a short term Balloon loan so I'm trying to figure out why you are?

The only reason I can figure out is that you would get a better short term rate? 10 years or so again towards the end I was getting something like 2.6% on my student loans. Are your loan rates not super low like that?
