If you get a FICO Scorewatch alert, you'll see this phrase:
Your FICO® score went down on a day when there were no credit alerts on your Equifax Credit Report™. This can happen if:
You moved from one category of credit users to another as time passed. For example, you may have transitioned from the category "consumers with a new credit history" to the category "consumers with a two- to five-year credit history". As a result, your credit report is evaluated differently, causing a slight change in your score. The good news is that moving between categories like this usually offers you the potential to reach a higher FICO® score in the future.
Not everyone seems to get one every time, and of course, if you're not in FICO Scorewatch, you won't get one anyway. I would guess that your credit report changed, of course, but I think these get sent anyway. And there tends to be a few days' delay, so if you do get one, check for that paragraph about moving from one category of credit users to another.
What makes up the various buckets is a deep, dark secret, but we all sit around the campfire and guess at it when we have strange and unexpected score drops. Mine came when I was added as AU to my husband's Discover card, and my total credit history went from 12 years to 18 years. Scores went briefly up, but a couple of weeks later, they dropped 15 points. (Ouch.) So it appears that somewhere between 12 and 18 years for oldest account, there is a new bucket.
You had a judgment removed, but you do still have collections displaying, so it appears that there is a different bucket for those with collections, but no judgments.
There have been a bunch of posts recently like yours, and it looks like this is what is going on --a baddie is removed, and it was the only or last baddie of its type, and it results in a bucket reassignment to a new credit peer group. (Scores can go up, too, when this happens.)
FWIW, my scores have really improved in the 9 weeks since this happened. I lost 15 points, but I have since regained those fifteen and another 20 points, so I'm happy with that. Hope it works out the same for you!
