I did not want to post this in the "Worst month yet" thread, as it was just getting totally off track.
Below is my progression with my FICO over the past 22 months or so. I bring it up due to the utilization discussion. I also bring it up here due to people's nature to hate big FICO swings. I do not buy notes on FOLIO with big FICO swings in recent months. Personally, I would not touch such a note with my FICO swings. I also do not worry about a 20 point swing either. It has been a very long time since I paid a penny of interest on a CC and own my house flat out and have not missed a payment that shows on my credit file. This is why it would be awesome to know what the root cause of FICO swings is due to. I speculated on FICO swings sometime back, but it was only speculation.
A Direct TV sold my "disputed debt" and it showed up on my report before I ever got a letter from the new company. This is not new to me as it was a 6-year feud. Once I sent a letter to the company about the "zombie debt" and contacted the 3 bureaus, it was removed.
B I took out 3 CC due to the awesome cash back rewards (Barclays, Citi, and Chase freedom). I had 15 months no interest so I let balances grow on my Citi. It hurt my FICO due to card utilization and overall utilization.
C I took out a Chase Slate card as it had a balance transfer of 0% for 18-months. So I stuffed it full and my FICO score plummeted even though my overall utilization did not change at all. The first rise was 22 points and the funny thing is my $25 payment took my card utilization from 90% to 88%.
D This quick drop was a large remodel on my house where I put a lot of materials on my CC from home improvement places. Not only did it mess up 2 cards utilization but also my overall. Most of the utilization issues were taken care of the next month when I paid one card off and brought my Citi to twice normal monthly utilization. (was still not paying interest on it.)
