Wow. My mortage is only 4.7% interest, and that's for a 30-year fixed loan. My student loan is fixed at 2.85%.
Yep, my mortgage is 5.25% FHA 30-year fixed, wanted to refinance, but only have a 780 beacon score and can't find a bank that will talk to me 30-year fixed under 4.75 without putting a lot of money down (which I don't have), even though I have well less than a 80% loan-to-value (got it in foreclosure several months ago).
The big problem with Sallie Mae loans is you can only refinance once. Ever.
Unless you're consolidating. When I first went to college, it was cheap, only $750 or so a semester for in-state plus books, so I paid cash. My last 2 years is when I did all my flight training and had to take out Stafford Loans, only $12,000, my total training and college was nothing compared to a lot of folks, so I'm lucky there.
But I ended up with two loans, one for the 1992-1993 school year and one for the 1993-1994. The interest was 11.75. I'm not kidding. So when the loan rates hit 9.25 and I got the consolidation letter, I was like "sweet!", not realizing (it was in the very fine print on page 4) that you could only do this ONCE.
Between switching jobs every 2 years after that for 6 years and making minimum payments and putting it in forbearance a couple times (layoffs, 9/11, etc), the loan is up to $25,000 after 15 years.
The only way to get a lower interest rate on your Sallie Mae student loan is to take out a 2nd mortgage and pay it off, or get another Stafford Loan, take 4 classes or so to be considered full-time, then combine those loans.
If I wasn't working, I'd probably be working on my MBA and doing just that right now... Wish Obama had fixed the "no refinance" policy along with all the other free money he's been throwing around.
