Hi Kt bear,
Thank you for your excellent question. The answer is somewhat dependent upon whether you are looking to build credit for the first time, continue building on what has already been established, or attempting to rebuild damaged credit. I will break the answer down based on these three scenarios. I would also caveat that "fast" and "build credit" do not always go together. It can take some time, and in the case of bad credit history, quite a bit of discipline and patience.
