Coldwell Banker has a great reputation nationally, but in order to choose a local branch to work for you need to do some research. I do know that ColdWell Banker doesn’t have very much of a presence in Brooklyn or Manhattan. In order to work effectively here you will need to be a REBNY member as well as a NAR member. In order to become a REBNY member you need to work for a brokerage that is also a REBNy member.
Hope that helps.
