What can and DOES change is whether you have a collector pursuing you for the debt. If you are talking about a dormant account that has been in collections and has finally been left alone with no collections activity for a few years, messing with it can be problematic from the point of view that the collections people will start pestering you again to see if they can get money and if the SOL isn't up, they can start reporting on it again which can affect your score or they could even file suit if your state SOL isn't up.
Credit repair can take some time. The process of disputing reporting errors with the credit bureaus is almost always a drawn out business, often requiring repeated efforts. And the task of rebuilding credit can take several months before new accounts are reporting and seasoned enough to create the credit repair benefit desired. On the other hand, there are some actions you can take to accelerate your credit repair progress dramatically.
According to VantageScore report on how credit behaviors affect your credit score, those with a low credit score may see a credit score bump of 5 to 10 points every month you use responsible credit behavior such as making on-time payments. And, you may see larger jumps of 35 to 50 points or even more if your score was low because of high credit utilization and you make a large lump sum payment to one of your cards and keep the balance low.
You cannot sign up for new credit cards, nor can you use the ones you have. While it may sound unreasonable to bar you from using credit, the point of your debt management plan is helping you dig your way out. “The last thing you want to be doing is running up more high-interest debt on the side,” said McClary. “You’re not doing yourself any favors in that situation.”
Remember, there are lots of reasons why your credit may be in rough shape. Most are related to your spending habits. So, for instance, if you missed a few payments or your debt levels are too high (think over 30% of your total available credit limits), disputing errors won’t help your case — you’ll have to make some changes to improve your credit scores. And you may have to wait a bit to see an uptick.
If you have missed multiple payments, perhaps its time to set-up payment reminders. In the digital age, you can schedule your cell-phone, laptop, and even email to remind you when a payment is due. On top of this, you can purchase sticky notes and post them around your entire home or office to remind yourself when a specific bill is due. In a lenders eyes, there should not be an excused for a missed payment. Just like the example of lending money to your friend, a lender is expecting to receive their capital back in a timely manner.
However, there is a big myth that you have to borrow money and pay interest to get a good score. That is completely false! So long as you use your credit card (it can even be a small $1 charge) and then pay that statement balance in full, your score will benefit. You do not need to pay interest on a credit card to improve your score. Remember: your goal is to have as much positive information as possible, with very little negative information. That means you should be as focused on adding positive information to your credit report as you are at avoiding negative information.
