Most likely it will lower your score, by how much is hard to say because each person will have a different result. But the lenders are concerned when those accounts went delinquent moreso than the last time they had activity (such as the event of a payoff). If the time they went delinquent/into collections was over 2 years ago then they would have been a non-factor if you hadn't paid them, but that's besides the point, so just work on your scores (if they aren't sufficient already) and when you get there the collections that you paid won't be an issue anymore.
