Forgot one of the more important factors earlier.....how long are you planning on staying in the house? We thought we were going to be staying for a while in our old place and pulled the refi trigger. Shortly thereafter we decided to start looking for a bigger home. Poor planning on our part, but we were enticed by the lower monthly payment. In the end, the refi ate up some of the valuable equity we had due to closing costs, etc. It turned out OK in the end, but we would have been better off staying with the old loan.
