I have searched for this with no luck. How will a student loan consol. impact my FICO score?
I really hope it won't drag it down!!!!

Once the unconsolidated loans reflect as paid and closed, the new loan won't have too much impact either way on your scores as an installment loan. It may temporarily hurt your Debt to Income while they transition over though (like if the separate loans aren't updated yet and the new one reports) or you may take a small hit temporarily because it's a new account but I can't remember if that always applies to installment loans. Predicting FICO is like throwing darts with a blindfold on: You can't really tell........

So long as you pay it timely, it'll have a positive affect.

Most of the time, installment loans don't really seem to have an effect on FICO unless you default - then the impact is HUGE. I have taken on several new SLs in the last year with no effect so far. And consolidating will actually help because the total monthly payments are usually less.

HTH.
