If you aren't playing with No20Khandout, though, it can be a good move for a poor family - teen grows up, moves out, then moves back with a 20K bonus!
This is one of the major reasons I am grateful for the no-20K handout mod. A couple can, for example, get divorced and then reconcile and move back in together without creating money out of thin air.
The big drawback, I'm finding is that when you start a new neighborhood, and your first Sim starts as a student, he's
really poor. Sleeping in an empty lot with a piece of lawn furniture for a bed poor. It's an interesting challenge in its own way, but it means his plans for children, etc., are on hold for a long time.
