We had no college savings either, but committed to squeezing $500 out of the budget every month starting January of our kid’s senior year of high school. The goal was to have tuition and fees for the fall semester at the community college all saved up in time for fall registration. She got lucky and was awarded a full tuition and fees scholarship at the CC, so we just kept on saving that $500 each month and put it toward her expenses when she transferred.
Look at your budget. What can you squeeze out of it? How long does it normally take for your husband to find a job again? Can you send some of your savings into an only-for-college account of some kind (not necessarily a 529, but maybe laddered CDs that come available in August and December when the tuition bills will hit)? And if there is a chance that your kids might end up at a community college for the first two years then transferring within the Ohio public system, go ahead and look at the articulation agreements for their potential majors and at scholarships that your commuting distance CCs might offer.
