Great advice! There is only one issue and I am honestly hoping this is just an unclear explation because I would be quite surprised that you got this wrong considering your line of work... Once a debt is charged off, it stays charged off. It can not be "re-activated", "re-aged" or "re-" anything. The law states that the Statute of Limitations (SOL) is fixed at the point which the debt is charged off and it stays the same no matter what. This won't change your credit score unless you can have that line of information removed from your credit report. A charged off debt stays a charged off debt whether you are paying on it or not.
This story is long winded and all, but the point is, it doesn't matter how bad you have screwed up. It happens to the best of people (I'm an alright kind of guy). But the only way to fix it is to put your foot down, get dirty and fix it. It won’t always be as quick as this and will most likely take a year or more to get in a good place. Then years of maintenance. But if you need a quick hit to your score in a good way, read through your reports carefully (with a credit advisor if you need to. Many personal banks will do this with your for free if you have accounts there in good standing) If it looks like there's something off or something you can fix, call your broker, go over the report with them and STRONGLY insist on a rapid rescore. They will get all your info and see what they can do.
In general, older consumers have higher credit scores than younger generations. Credit scoring models consider consumers with longer credit histories less risky than those with short credit histories. The Silent Generation and boomers enjoy higher credit scores due to long credit histories. However, these generations show better credit behavior, too. Their revolving credit utilization rates are lower than younger generations. They are less likely to have a severely delinquent credit item on their credit report.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
