I worked really hard in increasing my Transunion and Equifax credit scores by removing accounts from my credit. I had four accounts removed and my credit went up three times this month. When I checked my score yesterday noticed that it went down ** points for no reason. The reason they gave did not make sense. They wrote we found no changes to your credit report. We know it can be jarring when scores change but you don't see why. A few score factors are more 'invisible' like an account getting older or a scoring model changing its recipe. That was the worst excuse that I was provided from Credit Karma about how my credit went down ** points from going up * times this month from removing accounts from my credit. Now I only have one account in collections of $** which will be removed. But I am not trying to get into any credit card debt in the current moment because I am trying to be approved for a loan for a home. I would like a better explanation on how my credit dropped so many points when I worked so hard and getting them up.
