Basically. You'll get like 70 points once the report is clean. It will help with utilization and debt to income ratio though.
Keep in mind, those about 70 points are for a completely clean file. No derogatories at all. That being said, there's really nothing you can do other than harass them into removing it or wait.
With all due respect I disagree with collection accounts and utilization.In utilization only credit accounts are calculated.When collection accounts are present on your credit report ,as far as Fico is concerned the only two things matter.The fact that they are present and when they were opened,So whether you pay them or not will not effect your credit score.GOOD LUCK..
