I recently cancelled my "only" credit card and got a drop of 25 points on my fico. I did this because I opened a new CC account and it has not started reporting yet. I immediately called and re-opened the account to see if I would regain the 25 points.
I will give follow up once it is reopened to let you know if I get the points back.
Yea. You will get the 25 points back. I would not allow the number of cards if you can to drop below 3 with revolving accounts. If you can I'd get a third. Each card after 6 months it will start helping.
