Hello and welcome to the forums.
Start with pulling your FREE CR's from (ACR) annualcreditreport.com . they tend to have more info on them, then ones from a 3rd party. The CR's from ACR, come directly from each of the CRA's. You can pull 1 Free CR from TU,EQ and EX every 12 months.
Save your money and Don't Buy the Scores, they are what we call FAKO's.
Now once you have all your reports, you will need to go through them looking for information. What's good, what's bad. What you need to do to clean up and what you need to do to build new. If you have any questions, just post on here and we will be happy to help.
Answer to your question, yes, that will post as a positive TL. Good Luck!
