I would have once said that the student loan would fill the installment loan category, but I'm beginning to see things that make me wonder if they are treated differently. I had two small student loans, and never got any feedback on them, when they were open or when I paid them off early. But when I got a car loan several months later, I got happy chirps on the things-you're-doing-right screen for having an installment loan. I've read posts by others with similar experiences.
If it won't kill you to keep it open, you might do better to do so. It certainly won't hurt your mortgage app, and with luck, if it does affect your scores, it won't have been updated by the time you go to close on the mortgage. Even if it does, I don't think there's a big ding.
How's that for a lot of vague nothing at all??? Sorry about that...
