I pulled the financial numbers from U.S. News and World Report using just tuition, fees, and room & board. Obviously, the college’s page would be the final word on the subject. I usually just use the above fees rather than COA since not all colleges use the same amount for books, transportation, miscellaneous fees, etc. So I’d call Cal State SLO $44k, looking at its page, though certainly the extra $3k in costs are likely to be incurred. But they’d be incurred anywhere.
Based on the comments above from you and @DadOfJerseyGirl I’ll move SLO and Ga Tech up to Reaches.
