No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
My first priority would be to address the unpaid collections. They represent the chance of further damage.
You need two items of information in order to assess the unpaid collections. First, you need to know the DOFD on the OC account that led to the collection.
All flows from that critical date.
Next, you need to know whether the debt is still within your state statute of limitations. Look up your state SOL for the type of debt. Running of the SOL will most likely be from the same date as the DOFD on the OC account, but that can vary by state.
Once you have those dates, come back to the forum for some specific advice.
