TU finally excluded a judgment from 2007 today so I bought a new TU report to see that I LOST five points from 744 => 739.
The only negative left on TU is a 90 day student loan late from July 2007. Funny thing is that the Fico Score Estimator says that if I pay on time for the next three months (so the 90 day falls off) my score could go from the current 739 to an estimated 789-829!!
Starting Score: EQ 641, TU ???, EX ??? (myfico 6/7/13)
Congrats senor! Is possible, if you have 10+ years of solid history which from your registration date you might, and that 90 day late is your last derog (and it's a doozy) your score *might* react that way, but azguy is correct, the simulator can be way off historically.
This is just theory, but I'm not so surprised that you lost minor points on the judgement: when you get down to the last few derogs a bucketing event or two is likely to be expected. That may not have been what happened here, but while I suspect when you have a clean sheet you'll get a boost, for someone with just a 90 day late you may score worse against people in your bucket than when you had both a 90 day late and the public record judgement on your report.
The big positive on this for me is I didn't think it was possible to get much further than 720 on a '04 or '98 model even, maybe I can get to 740 on a mortgage score sometime before 2020

Thank you for posting, would love to see your update in a few months when the 90 day late fades to black.
I'm not expecting anywhere near 800. Just found it humorous that it estimated a possible 800+ score with a 90 day dropping off, after a judgment falling off LOST five points.
I'm getting ready for an app spree anyday, so I'll be getting dinged for multiple inquiries and new accounts. Although my AAOA may not be hurt too badly as it is currently 15+ years.
Another funny story about the Fico Score Estimator......
I decided to buy the EXP report here since it was a 666 last month AFTER the judgment was gone, but WITH the 90 day late.
This month, with the 90 day late gone, it went from 666 ==> 740.
The funny part is the one thing still listed as a negative on my report is high balance on installemt accounts (student loans at $100+K).
It said if I paid off the entire balance next month, my score could go from 740 ==> 795.
HOWEVER, if I paid off just $1 next month, it could go from 740 ==> 780. .............(smacks forehead)
