You can have multiple accounts, but the combined IRA and Roth IRA contributions for a tax year can't exceed the contribution limits for that year.Here's how the IRS puts it in Publication 590, Individual Retirement Accounts:Roth IRAs and traditional IRAs.
I am not sure how much, if at all, your FICO score will increase when the judgments fall off your credit report. Although not very common, under certain circumstances a judgment that has fallen off your credit report after 7 years can reappear. In addition to the 7-year credit reporting time period (CRTP), judgments also have a statute of limitations (SOL) on enforcement of the judgment.
The only positive in this situation is that in September, the collection account will be removed from your credit report, which should improve your credit history. The judgment should also be removed from your credit report seven years from the date it was entered. The bad news is the judgment will still be there, even though you can't see it on your credit report, lurking in the shadows, waiting for the worst possible time to jump out and surprise you. Expect that the creditor will decide to execute the judgment before it expires.
