fish, imo your scores may only change a little. But with that 90 day late on the report I'm not sure.
I read a post by a Mod last month, talking about the severity of lates. 90 days is considered as bad as a collection. If I can find the post, I'll re-post it here.
It went something like this(don't hold this to me):
30 day late - effects start to diminish after 1 year.
60 day late - effects start to diminish after 2 years
90 day late - effects start to diminish after 3 years.
(I wish I would have printed that post and put it in my folder.)
