We are in the identical situation as the OP and the chances that the $200,000 tuition savings would go towards a graduation gift condo for the child rather than into our retirement are slim to none! We feel an obligation to help the kids get through college without debt. But beyond that, they are going to be on their own when it comes to buying condos in the city. We still have another younger child yet to go!
