Hey again all, thought I'd post this, hoping it will help some of you trying to rebuild your credit.
Unfortunately, this is not necessarily a quick fix but it helped me. About a year ago, I took out a small signature loan for $2500.00. I realized this was a small amount but I was trying to balance out my credit report a bit. All I had on there was an old auto loan that was closed (with a few late payments) and a bunch of credit cards. The loan was for 24 months. I paid it off in 12 months. The installment loan helped my credit score tremendously.
If you can afford to do so and if you don't have any installment accounts, try taking out a small loan that you know you can afford to pay back. Paying it all back at once isn't going to help you any, but make on time payments to your bank and do your best to pay it off a bit early. Keep in mind if you are in serious debt and/or have very poor credit, most likely your bank won't give you a loan and an inquiry will pop up on your credit report which could hurt you. If you can afford a small loan and need to balance out your credit report, I believe this could really help!
That's it! Best of luck to everyone!
