It depends on how far into the mortgage process you are. If you are about to close or under contract I would not complete that debt consolidation loan until you close. If you are in the beginning stages, you should have time. The credit pull will effect your credit score. I am Mike Gracz from USA Mortgage and the Gustan Cho Team.
