Hi there 
My husband and I are in the process of having a home built, so needless to say I have been watching our FICO scores like a hawk and have subscribed to ScoreWatch for both of us.
Our LO had us pay down some credit cards to give him some points to balance out a late payment on his report. In late Dec he was at a 709 (which is the score he was approved with), but then as a few other cards posted he went up to a 726 a few weeks ago. We had sent a few GW letters to his student loan company hoping to get the lates removed but we were told no. ScoreWatch alerted me 2 weeks ago that the student loan company had added a "consumer disputes after resolution", even though we never ever said anything about disputing the late payment. I have been in contact with the student loan company and was told on Friday that the comments will be removed by the end of this month.
So yesterday I get a new alert that something had changed. I logged in and see that his score dropped to 711, but no explanation as to why. I compared the 2 reports and the balance amounts on the cards are the same, if not a little lower in the report I pulled today. No other new info reported. What could have caused his score to drop 15 points??
