Added a couple of Amex accounts-both will be backdated which will take me from an AAoA OF 5.2yrs to very close to an AAoA of 7yrs- also paid a big chunk of my cc debt off whiich will bring my utilities from 52% to 28%- my scores now are sitting @700 except EQ which is @680-my total length of ACC History is 16yrs- I've heard/read of rebucketing and am still not clear on that either- could I expect a score bump of,say 10/15pts maybe?(he says, hoping,
as he REALLY wants to get his scores all over 750 before he purchases a home)-lol
You HAVE TO promise to let us know the actual increase. I'm gonna throw in my guess as 27 points. I think AAOA might add like 5 ish points and at least 20 points from the UTI decrease. I'm tempted to say even more of an increase in score, but I'll go w/ 27 for now. 
When you find out, please reply to this post!
Starting Score: 584TU / 580EQ
