Grats. Nice gain. Figuring out what caused a score increase can be next to impossible. It may be a combination of factors and not one single item. The best way to try to figure it out is to have access to daily credit reports like USAA or another service and the compare the two reports. Check things like lates falling off, time since last late, decreases in reported UTIL, etc. Sometimes, you will just scratch your head and say "oh well at least it went up."
Congrats! Way to go! It's such a great feeling, isn't it? When you cick to view your alerts, and then you select the Details button, it should show you the old tradeline and then the newly reported information. Compare this to your pre-dispute report and you should get an idea of what caused the jump Either way though, congrats on the great progress!! Yay you!!
