After you set up a new entity or change your status and operate under any new entity, you then want to start building a credit score for that new entity. This video has some solid information. You wont worry about that old SSN based credit score after this. If you becoming more private, or have previous credit problems, this is an important part of the strategy to move on. Don’t repair credit, get new credit. No personal credit score needed. Take good notes.
Good luck!
