The cost differential is likely to be $7-8,000 or so.
With a federal loan ($5,500) and $2,500 on your part, that difference’s covered. Or, with only a subsidized loan ($2,500), a summer job ($3,000), and $2,500 on your part.
Or with federal loan and summer job and no “difference coverage” from you.
Personally, I think it’s a good trade off because the opportunities in her chosen major will be greater at Vtech - not $48,000 greater, but definitely $2,500 greater.
Are the $2,500 affordable out of income/savings? (If not, it makes sense for your daughter to take on federal loans an work).
If you told your daughter you could afford VTech, she gets in, and she likes it better, will you say she should attend FSU anyway? You have to be ready to tell her right now, so that she can prepare psychologically.
Or are you ready to let her make the choice, but explaining to her that if she picks VTech she has to work summers and take on a subsidized loan, but if she picks FSU she’ll have to do neither? (Or are you considering paying for the difference?)
