Even with a little higher in the interest rate you still can obtain some advantages than going subprime.
1. Typically no Pre-pay penalty. So instead of having to to wait two or three years to refinance or sell, you could do it sooner without a large fee on the pre-pay.
2. Subprime's 30 year fixed can be mighty high in the interest rate. Many cases the person goes more for a 2, 3, or 5 year ARM. In your case, you can have a more stable loan. Of course I'm only making an assumption that you are on a fixed loan
