It doesn't have to be huge, I don't think you're going to get a ton of people to move based on this financial incentive alone. A lot of people might have friends, family, or other ties to the region, and this is just what they need to convince them to make the switch. 15k isn't much, but it will cover a smaller move and closing costs pretty well for a lot of people. This is especially true if you're already in the Indiana/Wisconsin/Ohio area.
