Double interest
Although an unfortunate reality of refinancing, CommonBond should make more clear that you will likely be charged interest on both the new loan and the old loan during the transition period, even if your previous loan was also through CommonBond. In addition, it appears that the interest accrued on the previous loan during the transition is simply tacked on to the overall balance and even though the customer service rep says you get to "skip" a payment, this is not technically true. Refinancing is complicated and CommonBond should do a better job at making it uncomplicated.
